Blocks, with nothing in the way.
Block Lab takes the most addictive mechanic in block games — fitting pieces, clearing lines, watching the combo go off — and clears everything else out of the way. No timer pushing you, no lives gating your session, no screen full of buttons. Just open and play: a quick round on the bus or a full hour chasing your high score, the game bends to the time you have. The Prisma look — vivid gradients over a deep indigo-purple ground — gives it an arcade-room feel without overdoing it. And when you clear three lines at once, the game celebrates with you.

How to play
Block Lab gives you three pieces at a time and a 9×9 grid. You drag the pieces onto the board and, whenever you complete a row, a column or a 3×3 square, that region clears and frees up space. No clock is running: the round only ends when none of the three current pieces fits anywhere.
Think in three pieces, not one
The piece you place now decides whether the other two still fit. The most common mistake is solving the first one and locking the board with the third.
Let the middle breathe
Single-cell holes in the middle of the grid are hard to fill, because almost every piece takes two cells or more. Push pieces to the edges and keep the centre open.
Combos are worth more
Clearing two or three regions with the same piece multiplies your score. It pays to hold an almost-finished line and wait for the piece that closes several at once.
The bomb is the emergency exit
When the board locks up, the bomb clears a 3×3 area. It is optional: you choose whether to watch an ad to unlock it, and the game asks you first.
Block Lab questions
Is Block Lab free?
It is. Every mode and feature is available from the moment you install it. The game is supported by ads, and none of them interrupt a round in progress.
Does it work without internet?
It does. The whole round runs on the device. With no connection, only the ads fail to load — and the bomb stays available anyway.
Do I need an account?
No. No sign-up, no login, no email. Open it, play it.
Is there a timer or a clock?
No. There is no running clock and no time pressure. The round ends when none of the available pieces fits on the board.
Where is my progress kept?
On the device itself. High score, statistics and achievements are stored locally and never pass through a server.
Which devices does it run on?
iPhone and iPad through the App Store, and Android phones and tablets through Google Play.
Which languages is it available in?
Portuguese, English, Spanish and French, following your device language.
