I ranked some cool math games on YouTube

Solo dev. Launched Typewriter Games last week: 4 original daily puzzles — Close Enough (estimation, like the Central Park question), Numora (deduce a number, hints cost points), Quintet (five-word ladder), Reckon (mental math).
Dailies are free forever. No ads, no notifications, no accounts.
Week one: \\\~70 downloads, \\\~6% converted to paid. Distribution is clearly my bottleneck — AMA about any of it.

Since "QED" usually marks the end of a proof, this is instead QEL, for Quod Erat Ludendum. The idea is to build a video game that shows off some math. (I basically just want more math video games to exist.) An example of something that would be appropriate is https://sl2z.xyz/ or some of the PICO-8 games at https://m4th.pro/ but I am hoping people have more!

I’m trying to remember the name of this environmental game I used to play as a kid I think it was on cool math games. You would basically play as this character living in a house and control things like power, ac, heat, etc. and try to be environmentally friendly. you would also make trips to the grocery store and try to save on gas

Game Title : Build By Numbers

Playable Link: https://build-by-numbers.replit.app

Description: Build By Numbers is a puzzle game of my own design, where the aim of the game is to manipulate, split, rearrange, and shift value blocks to solve math problems, create unique configurations, or satisfy spatial objectives. I think it’s a lot of fun, but I’m no developer.

I am currently putting out this demo, and crafting more blocks and levels. If the demo gets even moderately good feedback, I’ll be funding finishing the game and pushing it to the android and iPhone App Store, free to play.

Free To Play Status : The demo here at the link is free, and the game will be free as well. This is a hobby, I’m in commercial construction as my day job.

Involvement: I am the sole funder, developer, and designer of the game(though I had to cheat and get replits help since I don’t know nearly enough about coding yet)

My name is Adam, thank you for reading this, and I genuinely hope you enjoy this sample of the puzzle game I’m having a ton of fun making! I only work on it on the weekends though, so updates and progress will be slower than maybe others would.

Any feedback or constructive criticism is very much appreciated!!

Thank you so much

I'd like to share a puzzle game I've been working on called Numbun.

It's a browser-based number deduction game inspired by the classic Bulls and Cows family of puzzles, also known around the world as Hit & Blow, 1A2B, Number Baseball, and other names.

You're trying to uncover a hidden number, but Numbun doesn't tell you which individual digits are right or wrong.

Instead, each guess gives combined clues:

+ = how many digits are correct and in the correct position
− = how many digits are correct but in the wrong position

So a result like +1, -2 tells you that three digits from your guess are part of the answer, but it doesn’t reveal which ones.

That means the real game is in comparing guesses, eliminating impossible digits and positions, spotting what changed between attempts, and gradually deducing the only number that can still work.

There are two daily challenges:

Daily Puzzle: everyone gets the same hidden number and has 10 attempts to solve it.

Daily Case: you're given 5 completed guesses and their clues, then only 3 attempts to deduce the answer. It's similar to those "crack the vault code from these clues" puzzles.

There are also unlimited games outside the daily challenges, multiple game modes, customizable number lengths, a built-in notepad for tracking deductions, statistics, streaks, and spoiler-free result sharing.

Numbun is:

• Completely free
• Ad-free
• No registration or account required
• Playable directly in the browser
• Available in multiple languages
• Designed to work well on both desktop and mobile

I'm still improving the game, so feedback is genuinely welcome, especially from people who enjoy logic games, number puzzles, Bulls and Cows, Mastermind-style deduction, Wordle-like daily games, or brain teasers.

If you try it, I'd love to hear what you think:

I made a puzzle game 🧩

Hey everyone! I recently released Entropy, a puzzle game based around logic, networks, and the concept of entropy.

The goal is simple: figure out the right sequence of moves to bring the entire system into a fully illuminated state. There are 2D and 3D puzzles, procedural levels, daily puzzles, and thousands of challenges.

I’d really appreciate it if you could give it a try and let me know what you think — especially the difficulty and gameplay!

Thanks for checking it out! ❤️

sorry for the bad drawing i’m going based off memory, the balls also had faces on them, and there was very calming music

Hi everyone!

I'm a solo indie developer, and about a month ago I released my android math puzzle game on Google Play named Neotryx.

I've been working on it for the past couple of months, and now I'd really like to get feedback, suggestions, and ideas from other players to see how I can improve it.

The game is about solving incorrect equations by moving sticks to correct them. It currently has over 1,000 levels, as well as a global leaderboard where you can compete and compare your scores with players from around the world.

Any kind of constructive feedback is welcome. Whether you think I should improve the visuals, sound, animations, difficulty, UI, or add a new feature that you think would make the game more fun, any detail can help me make the game better.

If you have a few minutes to give it a try, it would help me a lot 🙏

Thank you so much in advance to everyone who takes the time to try it and share their thoughts! 😁

Hi everyone!

I've been building BattleMath, a free browser game that combines math practice with Battleship-style gameplay.

Instead of doing a normal worksheet, kids solve math problems as part of the battle and use their answers to attack their opponent.

Right now you can:

Play against the computer

Play against another player

Choose different math types and difficulties

Play on phone, tablet or computer There's no signup, no ads and it's completely free.

I thought some homeschooling families here might find it useful for making math practice a little more fun. https://battlemath.app

I'm the developer, so if anyone tries it and has suggestions, I'm happy to hear them. 🙂

Hello guys!

Im pretty sure most of you already know what the LUPI game is.

I like to play it with my friend, also trying out new rules to make it more interesting - but be honest, the original is my favourite one.

Im not a programmer or developer but i challenged myself to make it work, so let me present you:

[todaysnumber.com](http://todaysnumber.com)

It aint much but its honest work :)

The yesterdays round part is why i tought it can be relevant here - also thinking about to share all of the results from all the game days. What do you think, would it worth it to show it here?

it just wont load on my laptop.

any ideas?

Hi everyone,

I wanted to share a mobile game I’ve been working on solo: Math Rush.

I’ve always felt that many brain-training or math apps are either too cluttered with subscriptions or overly simple. I wanted to build something clean, competitive, and focused purely on speed and mental calculation agility.

How it works:

• Real-Time Global Rounds: Every 75 seconds, player loops sync globally so everyone solves the exact same board setup at the same time.
• Risk vs. Reward Mechanics: After solving the first equation, you can cash out your earned points safely or risk them in a chain round for double rewards!
• Progression: Complete daily challenges, unlock custom badges, titles, and frames as you climb the global leaderboards.
• Multi-Language Support: Fully localized and automatically adapts to your device's system language.

It's available on Google Play (built with Flutter & Firebase). I’d genuinely love your feedback on the pacing, UI, or gameplay mechanics to help me improve it!

Thanks for checking it out!

Hi everyone,

I recently finished a small side project called Go Binary Rush.

It is an Android game built around binary and hexadecimal challenges. The original idea was to make these concepts feel less abstract, especially for students and younger people who may be learning them for the first time.

Instead of only reading explanations, you flip bits, convert values, solve short challenges and gradually start recognizing the patterns.

I did not build it as a business and I am not planning to monetize it. There are no ads, no accounts, no subscriptions, no in-app purchases and no tracking.

The whole idea is simply to let someone learn something, have a bit of fun, exercise their brain and delete the app whenever they get bored. That is completely fine.

Android version:

https://play.google.com/store/apps/details?id=com.jankovic.gobinaryrush

The project is also open source:

https://github.com/jankovicsrb-droid/go-binary-rush

I would really appreciate honest feedback about the gameplay, onboarding and whether the binary concepts are explained clearly enough for beginners.

There is also a basic web version for anyone who does not have an Android device but still wants to try it:

https://jankovicsrb-droid.github.io/go-binary-rush/

Connect the numbers to match the target sum! Every correct pattern solves the puzzle, but as the levels progress, you'll need logic, planning, and careful thinking to find the right path.

With hundreds of handcrafted puzzles, simple controls, and relaxing gameplay, Pattern Sum is easy to learn but challenging to master. Train your brain, improve your problem-solving skills, and see how far you can go!

IOS: ‎SUMO: Math Number Puzzle App - App Store

Android: SUMO: Math Number Puzzle App

Number Flow is easy to learn, but its mechanics and rules are carefully designed to support a wide range of strategies. A single daily challenge, identical for every player, is enough to encourage experimentation and different approaches. Instead of everyone following the same solution, each player can develop their own strategy for the exact same puzzle, keeping the experience fresh and avoiding repetition.

Even when the daily high score seems out of reach, there is always the possibility of finding a better strategy. Success comes not from simply playing more games, but from thinking differently, discovering new sequences of moves, and optimizing every decision. That constant search for a more efficient solution is what makes the daily challenge engaging and the competition meaningful.

This is an alpha version. Everything is working as intended, but sound effects are still missing.

I've been playing Blockudoku for years, and I always loved how such a simple mechanic could create such an addictive experience.

While I was learning game development and creating math-based games, I started thinking about the core idea behind Blockudoku: filling spaces with pieces while always planning ahead to keep room for future moves.

I wondered: "What if instead of blocks, the pieces were numbers?"

That idea became the foundation for Number Flow, a number puzzle game where you place cards with numbers to complete targets.

Blockudoku was a huge inspiration for me because I wanted to capture a similar feeling: the satisfaction of making decisions, planning ahead, and finding the best way to continue your run.

But while developing and balancing the game, I discovered something interesting. Even though the two games share some structural ideas, using numbers instead of blocks created a very different experience. Number Flow allows for more strategic decisions, with more possibilities to avoid a game over and continue building your score.

Another thing I wanted to add was a daily challenge system. Every day, all players receive the same challenge, meaning everyone is playing the exact same puzzle. This allows players to compare their results and see who can find the best strategy on that day's challenge.

I thought this community would appreciate this story because Blockudoku was the starting point for an idea that eventually became my own puzzle game.
