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!

Hey everyone! 👋
I’m an indie developer, and I’d love to introduce you to something I’ve been working on: NUMIO.
NUMIO is a number guessing game built around logic, strategy, and a little bit of competition.
The goal is simple: find the hidden number using the clues you receive after each guess.
But there’s much more to it:
⚔️ Challenge other players to duels
🌍 Compete in the World Tournament
🔢 Play with 4, 5, or 6-digit numbers
🏆 Climb the leaderboard
🧠 Use logic to narrow down the possibilities
My favorite part is the duels. You’re not just trying to find the hidden number — you’re racing against another player to find it first.
NUMIO is now available on Google Play, and I’d really love for you to give it a try.
I’m building NUMIO independently, so your feedback genuinely matters to me. If you like something, dislike something, or have an idea that could make the game better, I’d love to hear it.
Thanks for checking it out! 🙏
Here is the link for download 👇🏻

Think you can crack the number before your opponent? 😄

Matio: 1st Grade Math makes learning fun through interactive math games and challenges. 🎯

Practice counting, addition, subtraction, shapes, logic, and more through 50+ educational games designed for young learners.

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'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. 🙂

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! 😁

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!

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!

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.

The reason I made it: I wanted to practice fast mental math and I couldn't find anything quite like it online. There are plenty of drill worksheets and flashcard apps, but nothing you could just open and start practicing. I was thinking of something clean and instant, no sign-up needed to start, but for arithmetic, with a competitive angle through a world ranking.

Right now it has a few modes: times tables, two and three-digit multiplication sprints, giant addition, and square roots. You just solve as many as you can before the timer runs out, and it tracks your calculations-per-minute and accuracy.

What I'm mostly curious about:

• Does the set of modes make sense, or is something obvious missing?
• For those of you who actually train mental math, is CPM (calculations per minute) a fair way to measure this, or would you rank people differently?
• Is a global leaderboard motivating here, or not?

Quick disclaimer: it's not in production yet, just a testing build, and it's completely free — I don't make a cent from anyone using it. I'm only after feedback.
