About the Game
Stack pieces and survive to the end! Speed increases per level, 3 difficulties and timed survival mode.
Educational Benefits
- 1Develops spatial reasoning by fitting pieces into different positions under time pressure
- 2Trains divided attention and forward planning by watching the next piece while placing the current one
- 3Stimulates fast decision-making and priority management in high-pressure situations
- 4Improves coordination between visual perception and motor response in high-speed phases
- 5Builds resilience and recovery ability by continuing after losing a life
How to Play
The goal is to survive until the phase timer runs out without the block stack reaching the ceiling. Pieces shaped like L, J, T, S, Z, I and O fall from the top of the board (10×20 cells). Position them to form complete horizontal lines — each completed line is cleared, opening space and earning points. Controls: use ← → to move the piece sideways, ↓ to speed up descent (soft drop), ⟳ to rotate 90° clockwise, and ⬇ to instantly drop the piece to its final position (hard drop). The gray ghost piece shows where the current piece will land — use it to plan each move. The HOLD button (or C key) saves the current piece for later — an essential strategy in advanced phases. The NEXT panel shows the upcoming piece so you can plan ahead. Each difficulty has 10 phases: drop speed increases at each phase, making survival progressively harder.
Tips & Strategy
- 1Keep the stack as flat as possible — columns at similar heights prevent gaps from becoming inaccessible.
- 2Use hard drop (⬇) for pieces whose position is obvious; save soft drop (↓) for last-minute fine adjustments.
- 3The I-piece is most valuable for clearing 4 lines at once (Tetris) — keep a narrow vertical channel specifically for it.
- 4Use HOLD strategically: if a piece does not fit now, save it and use the next one; in fast phases this can save a life.
- 5In hard phases, prioritize survival over score — one fewer cleared line is better than an unstable stack that ends the game.
Frequently Asked Questions
What is survival mode?▾
Instead of playing indefinitely, you need to keep the blocks below the ceiling for the set time in each phase. Survived until the countdown hits zero? Advance to the next phase.
How many phases and difficulties are there?▾
There are 30 phases in total: 10 per difficulty (Easy, Medium and Hard). Piece speed increases at each phase and each difficulty level.
What does the HOLD button do?▾
It saves the current piece to use at a better moment. You can swap the held piece with the current one at any time, but only once per piece — use it strategically.
What happens when I lose a life?▾
The board resets but the timer keeps running. You start with 3 lives per session — lose them all before time runs out and the game ends.
