Block Stack
Score: 0 Best: 0
Move, rotate, and drop falling blocks to clear full rows before the stack reaches the top.
How it works
- Use the left/right buttons or arrow keys to move, up to rotate, and down to drop faster
- Check the "Next" preview in the top bar to plan ahead for the piece after your current one
- Clearing a full row scores points — clearing several rows at once scores a lot more
- Pieces fall faster as your score climbs; the round ends when a new piece has nowhere to spawn
Frequently asked questions
What is this?
A twenty-third and final tiny promotional game in this batch, in the same spirit as the others — a Tetris-style falling-block game, built entirely client-side.
Is my best score saved anywhere?
Only your best score, and only in your own browser's local storage.
How is scoring worked out?
Clearing 1, 2, 3, or 4 rows in a single drop scores 100, 300, 500, or 800 points respectively — clearing multiple rows at once is always worth more than clearing them one at a time.
