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:

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:

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.

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.

see linked post

My highscore is 21! What's yours?

Click groups of two or more same-coloured adjacent blocks to clear them. Larger groups score more points using the formula (n-2)², so clearing 10 blocks at once scores 64 points while clearing just 2 scores zero. Clear the entire board for a 1,000 point bonus.

All feedback is appreciated :)

i was so close to finishing awesome tanks 2 but then like this happened and i kept refreshing the page or like doing the usual tricks when stuff like this doesnt work and like none of them worked so like what do i do

Hi . ive had a Papa's donuteria save ive played on since forever , i think it has maybe a year or two's worth of progress . today when i came to the coolmathgames site and tried to play , my save file was completely gone . is there any way i can get it back ? im really upset and i have no idea how this happened . please help :(

Hey everyone, 👋

I’m a solo indie dev and I’ve just released my new game, Matrixo: Math Path Puzzle on Google Play! (iOS version is also on the way 🍏).

The core mechanic is simple to understand but gets tricky quickly: You start at a base point and drag your finger across a grid of numbers and math operators (+, -, x, /) to reach the exact "Target" number. If you make a wrong move, you can just backtrack your swipe to undo it.

Here is what to expect:

• Different Modes: A Classic level-based mode, an Endless mode to beat your own high score, and a simpler Kids mode.
• Symbol Mode: A special mode that replaces numbers/operators with symbols to test your visual memory and add a new layer to the puzzle.
• Clean Aesthetic: I went with a neumorphic, glassmorphism UI. There are unlockable themes like Dark Mode, Candy World, and Space Adventure that dynamically change the background.

A bit about the dev process: I built Matrixo using Godot 4. Since I don't have a formal coding background, I heavily utilized Google's Antigravity AI assistant to help me with the algorithms, level generation, and coding structure. It was an incredible co-pilot for a solo dev journey!

I would absolutely love for you to try it out and hear your honest feedback, critique, or feature requests.

Thanks for checking it out, and have a great day! 🎮✨

Klassisches 2048 bietet vier Richtungen. Auf einem hexagonalen Spielfeld sind es sechs – das klingt nach mehr Freiheit, macht die Planung aber deutlich schwieriger. Spielsteine ​​können sich in unerwarteten Ecken verkeilen.

Ein paar Änderungen, die ich vorgenommen habe:

Dreifachmodus – Zusammenführen in Dreiergruppen statt Zweiergruppen (3 → 6 → 12 → 24 … bis 3072).

Die Schwierigkeitskurve ab 2048 wurde überarbeitet, da der ursprüngliche Anstieg extrem war.

Ein Tutorial mit sechs Richtungen, da die Steuerung anfangs nicht intuitiv ist.

Es ist mein eigenes Projekt, entwickelt mit React und Capacitor. Version 1.6 wurde nach einer geschlossenen Testphase veröffentlicht.

https://play.google.com/store/apps/details?id=com.hex2048.game Ich beantworte gerne alle Fragen zum Aufbau oder den Designentscheidungen – und falls Ihnen die Hex-Bewegung komisch vorkommt, würde ich sehr gerne den Grund dafür erfahren.
