After 3 days of coding, I'm excited to share my custom JavaScript Tetris game with you all! This isn't your regular Tetris - I've added some unique features to make it stand out:
GAME << PLAY HERE
U can Look into the code >> GITHUB
✨ What makes it special:
- Explosive Bomb Pieces that clear surrounding blocks when they land
- Glowing block effects with custom color schemes
- Smooth animations using GSAP for line clears, drops, and rotations
- Satisfying visual feedback for every action (screen shake, flash effects)
- Game over sequence with a clean overlay and restart option
The game has all the classic Tetris mechanics you know and love, but with these visual upgrades that make it feel modern and satisfying to play.
`
🧠 Key Functions Behind the Scenes:
-
gameLoop()- The heart of the game that maintains timing and updates -
collision()- Handles all collision detection for precise piece movement -
activateBomb()&animateExplosion()- Create that satisfying bomb effect -
rotate()- Implements piece rotation with wall kicks for smooth gameplay -
clearLines()&animateLineClear()- Detect and clear full rows with animations -
renderGame()&drawGlowingBlock()- Create the visual magic on the canvas`
🕹️ Controls:
- Arrow keys for movement and rotation
- Space bar for hard drop
- Press R to restart after game over
Building this was an incredible way to test and level up my JavaScript knowledge. I got to work with canvas rendering, animations, event handling, and game state management all in one project. The challenge of implementing collision detection and piece rotation really pushed my problem-solving skills!
What surprised me most was how enjoyable the whole process was. Even when debugging tricky issues like the bomb explosion animation or handling input during animations, I found myself completely immersed in the work. It's been one of the most rewarding coding projects I've completed so far!

That's an awesome little game to have built in 3 days!
The screen shake when a bomb goes off is definitely very satisfying.
I am writing a canvas based game engine right now and that is an effect that I have yet to implement. I may take a look at how you accomplished it.
Yeah that really feels satisfying when that bomb explodes!!!
A canvas based game engine this seems interesting. Have u shared some demo or doc?
I haven't released anything about it yet. It's still a work-in-progress but I will be ready to share some details soon. I'm building it as an entry for a hackathon and am keeping it mostly quiet until the deadline is passed. You should consider submitting your game if you are eligible. I could definitely see this a custom post type on reddit with the leaderboard and big button to open a webview that your game runs in.
Dude i just saw what previous Winner made and this game wont stand a chance. But really that drives me to make something amazing in the future.
Good Luck for yours my G!
wow those bombs are so annoying!!
Not a Surprise for You 😂.
Awesome! Everything is very smooth
Thanks my man!!!!!
