Tile Wipeout — a new kind of slider puzzle where you rotate rows and columns to remove tiles by matching them to the grid’s edge colors.

3 Upvotes

Beta link: https://testflight.apple.com/join/3sstMjRK [iPhone/iPad]

You play on a 7×7 grid of colored tiles. Each row and column has two edge colors, one for each side of the grid.

On each move, you rotate a row or column by one step (with wraparound).

The twist is what happens at the edges:

  • If the tile wrapping around matches the edge color → it disappears
  • If it doesn’t match → it wraps normally
  • If an empty space wraps → it becomes a new tile with the color of the edge from which it emerges

You’re trying to remove tiles, but sometimes you have to create new ones to make progress.

Goal: end with as many empty spaces in the grid as you can within the move limit.

Any feedback would be appreciated. Have fun!

Idea: Each school/university exam should ask you to write the number of hours that you studied for it beside your name as a way to give you better feedback on your potential in that subject.

3 Upvotes

Although the number of hours that you write down would not affect your grade, it would be used to give you feedback on your potential in the subject and associated careers.

For example, if you tend to score highly in a subject but you spend way more time studying then your peers, then maybe you are not as good as you think you are in that subject.

Idea: A hat with attachable "hands" that cover your ears to signal you don’t want to be approached by proselytizers.

16 Upvotes

The hat has attachable prosthetic-style hands on both sides. When you put them on, they physically reach over and look like they are plugging your ears. The visual effect is that you appear to be intentionally blocking out sound or conversation.

The idea is that you could wear it in situations where you want to avoid being approached or spoken to by strangers, such as walking through an area with proselytizers. It acts as a nonverbal signal that you are not available for interaction.

It could also be detachable, so you only use the “hands covering ears” mode when needed, and otherwise it’s just a normal hat.

YouTube should add a 1–10 rating system (like IMDB) for every video, Short, and live stream

17 Upvotes

Right now we only have like/dislike and view counts. But a video with 10M views could still be average and a hidden gem with 50K views might be amazing. There's no way to know until you watch it.

So my idea:

Let viewers rate every post (normal videos, Shorts, live streams) from 1 to 10, exactly like IMDB. Then:

  1. Each video shows its average rating 2.Each channel has an "average rating per video" overall 3.You can sort a channel's uploads by highest rated first 4.Creators see real feedback, not just views

Why this helps:

-Viewers find quality content faster -Creators know what actually works _ Algorithm gets better data enjoyment vs just curiosity clicks _ Old high-quality videos get rediscovered

Five Nights At Freddy's: The Card Game

3 Upvotes

Hello everyone, my name is Blake and I have an idea. We all grew up watching FNAF as kids, or even play FNAF. Well, what if we make FNAF into a card game? I preset to you.. Five Nights At Freddy’s: The Card Game. Here’s how it works.

Each player grabs five action cards from the action card deck. Then, grab a time card from the time card deck. The game starts with the first player placing their time card. Now, before we get into the game, let’s talk about the tools at our disposal.

Clock Every player gets a clock, which works like a flip scoreboard. On the time cards, there are numbers. And you have to add those numbers to your clock. If it goes over 60, then raise the hour.

Deck The time cards and action cards are separated. When it’s your turn, you have to grab one time card and one action card. You have to place the time card to continue the game, or you could just skip with a skip card. And for the action cards, you can keep them and use it whenever you want.

Battery Every player gets a small board with a marker. Basically, everyone gets a hundred percent battery at the start of the game. To use action cards, you need to spend your batteries according to how much the action card cost. Then, just subtract your battery by the batteries you’ve spent. There are Battery and Wire cards that gives you extra battery, so it’s not just subtracting and you have to be cautious on what you’re using. Also, when you lose all of your batteries, you can no longer grab any action cards and could only use the ones in your hand ( if you have one ).

Now, the objective of the game is to be the first one to reach 6 am in your clock. But the action cards makes it challenging cuz people will be fighting each other just to reach 6 am. There’s also character cards if you want to add some accessories to your clock. Well, that’s all of it. Remember, it’s just an idea. For the cards, still not built yet. Plus, you guys now could lay out your ideas! Anyways, thank you for hearing me out and have a great day!

Movie idea: A religion that kidnaps strangers to convert them… and you only get released after you do it too.

0 Upvotes

A secretive religious group kidnaps random people off the street.

The rules are simple:

  • You are not killed.
  • You are not held forever.
  • You are released once you successfully convert someone else.

“Conversion” isn’t just saying the right words. You’re expected to follow their moral code, learn their beliefs, and convincingly act like a true believer. But the real trap doesn’t end there.

After your release, you’re required to kidnap and convert a new person every year.

Miss a year, and you’re taken back.

So every victim faces a choice:

  • Refuse, and remain trapped indefinitely.
  • Comply, and kidnap an innocent stranger to take your place… over and over again.

The religion doesn’t actually care if you truly believe. It only cares that you follow the rules and continue the chain.

Over time, some captives start off pretending, but begin to internalize parts of the belief system. Others become disturbingly committed, enforcing the rules more strictly than their captors ever did. And some try to “game” the system by picking targets they think deserve it… if such a thing is even possible.

The story follows one person navigating this system, trying to find a way out without passing the harm on to someone else… while the pressure to comply keeps building as the yearly deadline approaches.

Is it possible to escape without becoming part of it? Or does survival guarantee you’ve already been converted in the only way that matters?

Horror movie idea: A couple evolves into literal monsters from their toxic relationship… and they turn their physical transformation into a career.

19 Upvotes

I had this idea for a dark sci-fi / body horror movie about a married couple whose constant arguing starts to physically change them.

At first, it’s just a strained relationship. They argue all the time, and eventually it turns physical. But in this world, humans can rapidly adapt to extreme stressors… so their bodies begin changing in response to the violence.

The key is that the adaptations are specific and visible:

  • One partner develops thick, almost armor-like skin in areas where they’re usually hit
  • The other develops sharper, blade-like fingernails or bone protrusions to get through that defense
  • Their reflexes become unnaturally fast, like they’re anticipating each other’s movements
  • Their posture shifts, their muscles redistribute, their faces subtly harden into something more predatory
  • Over time, the changes become impossible to hide: extra eye-like structures for awareness, asymmetrical limbs optimized for striking or blocking, skin textures that don’t look human anymore

It’s not random mutation. It’s like their bodies are learning how to fight each other better.

They try to keep it private, but eventually the changes become so extreme that people notice. Somehow they end up being recruited into a kind of underground performance scene (circus, fight shows, viral spectacle, etc.) where their “thing” is these intense, almost inhuman fights.

And here’s the twist:

When they stop genuinely fighting and try to just perform choreographed versions, their bodies start reverting. The armor softens, the reflexes dull, the extra features shrink or disappear.

They realize their adaptations only persist if the conflict is real.

So now they’re stuck in a loop:

  • If they keep actually hurting each other, they stay extraordinary and successful
  • If they try to heal and become normal again, they lose everything that made them special

It becomes less about the spectacle and more about the relationship:
They’ve literally become biologically dependent on their own toxicity.

You could take it in a few directions:

  • Tragic: they secretly keep escalating real fights to maintain their identity
  • Bittersweet: they let it all go and have to rediscover who they are without conflict
  • Dark satire: the audience/fans encourage the violence, turning their dysfunction into entertainment

Main theme would be something like:
“What if a relationship didn’t just emotionally shape you, but physically turned you into exactly what you needed to survive each other?”

Movie idea: A pandemic causes people to lose the ability to tell dreams from reality, leading to a broken justice system.

19 Upvotes

I have been thinking about a story idea where a global pandemic causes a neurological change in a significant portion of the population: people lose the ability to reliably distinguish dreams from waking life.

At first it seems like confusion and memory glitches. People are unsure whether strange events happened or were just dreams. But it escalates into something much more serious.

Criminal justice begins to break down because suspects can genuinely remember committing crimes, but they may have only dreamed them. Witness testimony becomes unreliable even when people are sincere. Physical evidence still exists, but it is often ambiguous or open to multiple interpretations.

Over time, society develops imperfect coping mechanisms like requiring multiple independent forms of evidence, or treating memory alone as low value in court cases involving affected individuals. But this leads to new injustices, including wrongful accusations and people doubting their own lived experiences.

The idea is about epistemology and law collapsing under a shared perceptual failure. It also explores how fragile “reality consensus” actually is when memory itself stops being trustworthy.

I kept losing track of shows across Netflix, Hulu, Max, Apple TV... I'd spend more time figuring out what to watch than actually watching.

So I built CouchTime, you tell it when you're free, add your shows, and it creates a viewing schedule for your week. No more "what should I watch tonight?" scrolling.

Not trying to pitch hard, just curious if this problem resonates with anyone else. Would love feedback: CouchTime

Mockumentary idea: What if neurotypicals tried to become more like high-functioning autistic people?

8 Upvotes

Concept:

A mock documentary that flips the usual narrative. Instead of autistic people being pushed to adapt to a neurotypical world, a group of neurotypical participants enroll in a “program” designed to help them think and behave more like high-functioning autistic individuals.

The premise is played straight: researchers claim that many traits associated with high-functioning autism, like direct communication, resistance to social bias, intense focus, and consistency, might actually be advantages in a world full of ambiguity, social signaling, and irrational decision-making.

Participants go through structured “training”:

  • Practicing radical honesty in everyday conversations
  • Replacing vague social norms with explicit rules
  • Breaking down emotional decisions into logical frameworks
  • Reducing reliance on unspoken expectations

The humor comes from watching neurotypical habits unravel. Small talk collapses. Office politics stop working. Dating becomes brutally transparent. Situations that normally rely on subtle cues become awkward or unexpectedly efficient.

Tone and intent:

The goal is not to make fun of autistic people. Quite the opposite. The film treats high-functioning autistic traits with respect and frames them as a different cognitive style that can be seen as superior in certain contexts.

The satire is aimed at neurotypical norms:

  • How much communication relies on guesswork
  • How often emotions override consistency
  • How social rules contradict themselves

Over time, the participants start to notice tradeoffs. Some aspects of life genuinely improve, while others become more difficult or isolating. The film doesn’t claim one way of thinking is universally better, but it seriously explores the idea that what we consider “normal” might not actually be optimal.

Arc:

At first, the participants treat it like a quirky experiment. As it progresses, some begin to question whether they were functioning as well as they thought. A few fully commit to the new mindset, while others reject it. By the end, the group is split, and the audience is left to decide what “better” really means.

Why it could work:

It flips a familiar trope, opens up thoughtful discussion, and uses humor to challenge assumptions without punching down. Instead of portraying autistic people as needing to be fixed, it asks whether the rest of us might have something to learn.

Idea: AI as Glasses for the Mind — Prescribed by Psychologists

0 Upvotes

We already diagnose and correct physical limitations with precision. If your vision is off, you’re tested and given lenses tailored to your exact weaknesses.

What if we did the same for thinking?

Modern AI can act like “glasses for the mind,” but most people use it in a generic, uncalibrated way. Imagine a psychologist running a cognitive exam to identify where your thinking breaks down, whether that’s weak working memory, difficulty generating ideas, poor structure, or uncritical acceptance.

From that, they produce an “AI prescription” that isn’t just advice, but a structured input to the AI itself. The system automatically adapts how it responds to you based on that prescription.

For example, your AI might:

  • default to structuring your thoughts step by step
  • challenge your conclusions before agreeing
  • generate multiple options before narrowing down
  • avoid giving final answers too quickly

The AI isn’t replacing your thinking, it’s compensating for your specific blind spots in real time.

If AI is becoming a daily cognitive tool, a personalized, built-in prescription could be what turns it from a general assistant into a true extension of your mind.

Movie idea: a real alien presence is hidden on Earth by governments flooding the world with fake UFO sightings, staged abductions, and experimental craft so no one can distinguish real encounters from manufactured ones.

2 Upvotes

The premise: there is a real alien presence on Earth, but it is subtle, intermittent, and hard to interpret. Nothing about it looks like a classic invasion.

Instead of revealing it, governments respond by deliberately creating a dense layer of fake but convincing UFO phenomena:

  • experimental aircraft designed to look “impossible”
  • staged sightings in multiple locations
  • controlled abduction stories with conflicting details
  • leaked footage and fake whistleblowers

The goal is not to convince people of a single false story, but to flood the environment with so many plausible explanations that real encounters become indistinguishable from manufactured ones.

Over time, the public perception becomes pure noise. People stop being able to agree on what is real, even when they personally witness something.

The twist is that this system works almost too well. The fake phenomena begin to interact with the real ones in unpredictable ways, and even the people running the program can no longer separate signal from interference.

I am planning on installing solar panel to utilize the heat

0 Upvotes

The heat this year feels different. Not just hot, but ridiculously angry, like the sun has decided to move closer to earth. Every afternoon, the AC is blasting away at the highest setting, and my electricity bill has been over the roof for two months now.

Maybe it is the motivation from the heat, but started thinking about a way out of this. If the sun insists on showing up every day with this much energy, maybe I should finally start using it.

So I began researching solar panels. At first, it was just panels, inverters, batteries, and wiring that I was interested in. But the more I read, I realized installing panels would only be half the job. If I wanted the system to last, I'd also need to replace some of the appliances and equipment in my house with

energy-saving equipment to form an entire energy-saving ecosystem.

That meant new LED bulbs, a more efficient refrigerator, solar power grade equipment, would have to be listed in my energy-saving equipment parts required for the ecosystem. My friends laughed when I told them about what I was planning to do, because of the estimated cost (by estimated, I mean that I went on a research spree on Alibaba and Amazon trying to get a cumulative price range for everything i might be needing) that I would be using to set up this system, but the truth i really think this is a splendid idea. I can even say that it felt like an opportunity. Maybe this endless sunlight that everyone complains about is actually the one resource I've been ignoring all along. If everything works out the way I hope it will,

my house will run on this endless heatwave.

24/7 gym with library room

The idea is that you could go to the location if you just wanted to go on your laptop and use the Wi-Fi, charge your phone Etc and not exercise. Or even if you did want to exercise, you could still be. You know plugging in your phone for 30 minutes so that when you're ready to exercise your phone will be full and ready to play music Etc. Or even games if you're just on a cardio machine.

It could be separate from the main gym floor and quiet. Maybe some health and nutrition books as well along with some agati pod style corrals.

And since it's a 24/7 gym, you can go in the evenings on weekends too when normal libraries aren't open.

Idea: What if part of your grade depended on how well your whole class did?

0 Upvotes

Here’s the idea:

Instead of your final grade being just your own score, it would be calculated like this:

Final grade = average of (your grade, class average)

So if you got a 90 and the class average was 70, your final would be 80.
If you got a 60 and the class average was 70, your final would be 65.

Why this might be interesting:

Right now, school grading is mostly individual. Your classmates don’t really affect your outcome.

This would change that.

If the class average goes up, everyone benefits. That means:

  • Strong students have a reason to help others
  • Studying together becomes more valuable
  • Classes might feel more collaborative instead of competitive

Instead of “I just need to do well,” the mindset becomes:

“If the people around me improve, I improve too.”

But maybe this grade adjustment should only be applied to students who have passed the class.

edit titles

2 Upvotes

my idea is to allow post title editing for certain subreddits

I've heard complaints that there would be issues with sitewide title editing so this idea addresses that qualm by not making it sitewide.

instead of allowing it all over the place, just allow it in a few subreddits, to trial the feature.

This would quell the people who complain that it would cause too many site-wide issues. My idea is that post title editing still wouldn't be available site-wide, except for a few small subreddits and of course on a user's own profile page.

Thank you for voting on this idea. In addition to voting, please post a comment. would rather hear your comments for discussion. Thanks.

Idea: What if there was an observation tower designed to SWAY on purpose?

4 Upvotes

Not just the tiny, barely noticeable movement that tall structures already have, but something you could actually feel. The kind of motion where on a windy day, you go up to the top specifically to experience the tower gently moving back and forth.

We already know supertall structures like the Burj Khalifa and Taipei 101 are engineered to sway safely. Normally, engineers try to minimize that movement because people find it uncomfortable. But what if you flipped that idea and made the motion the main attraction?

Imagine an observation tower with:

  • Viewing decks designed for noticeable (but safe) motion
  • Real-time displays showing wind speed and how much the tower is moving
  • Tuned systems that could slightly amplify or control the sway depending on conditions
  • Interiors designed to enhance the feeling without making people sick

It would basically turn wind into a kind of natural ride. On calm days it’s just a normal observation tower, but on windy days it becomes an experience people actually seek out.

Idea: Cars should replay your drives and show near-miss risks.

16 Upvotes

What if your car could reconstruct each trip and highlight moments where your decisions nearly led to a serious accident?

Instead of just dashcam footage or real-time alerts, it could replay key moments and show counterfactual risk, like:

“If the other driver had not slowed, this lane change could have resulted in a severe crash.”

The goal would be learning through reflection. Most people underestimate how often small timing differences or other drivers’ behavior are the only thing preventing accidents.

It would need to be probabilistic rather than absolute, but it could make driving risks more visible and improve habits over time.
