Tetrofall is a falling-block puzzle with one twist that changes everything: a new row pushes up from the bottom of the board on a timer. You're not just filling a well — you're racing a floor that never stops rising. Clear rows to buy back space. Survive as long as you can.
A CASCADE, NOT A SHIFT
Clear a row in the middle of your stack and the blocks above it don't slide down as one piece. Every block falls independently until it lands on something solid. Columns collapse at different speeds, gaps open where you didn't expect them, and rows finish themselves. Every link in a cascade chain raises your multiplier by another 50%.
THE PRESSURE NEVER LETS UP
• Rows rise every 22 seconds when you start — every 4.5 seconds by minute twelve
• Early rows leave a clustered, forgiving gap; late rows are dense and scattered
• Difficulty interpolates smoothly the whole way — no sudden jumps, no plateau you can memorise
• Beat your best and your next run starts further up the curve
