One tower. One button.
A block slides back and forth above your tower. Tap, click or press Space to drop it — whatever hangs over the edge gets sliced off. Everyone in the world plays the exact same level today. How tall is your tower?

How it works
Watch it slide
Each new block sweeps across the top of your tower, faster and faster as you climb. Today's speed pattern is the same for every player on Earth.
Drop with one button
Click, tap or press Space to drop the block. Land dead-on for a PERFECT — the block snaps into place at full width. Overhang the edge and the excess is sliced away.
Don't miss
Miss the tower completely and the run ends. Your score is the height of your tower — then share it and dare your friends to beat it on the same level.

Frequently asked questions
What is today's level?
Every day at your local midnight, a new level is generated from that date's seed: the speed and starting direction of every block in the tower. Everyone who plays on the same day faces the identical sequence — so score comparisons are fair, no luck involved.
How do I play?
One button does everything: click the tower, tap the screen or press Space to drop the sliding block. The part that overhangs the block below is cut off, so each mistake makes the next block narrower. A near-perfect drop (within a hair) snaps into place and keeps the full width.
What counts as the score?
Your score is the number of blocks you stack on top of the base. Perfect drops are counted separately — a shorter tower with all perfects is its own kind of bragging rights.
Can I replay a past day's level?
The daily level is only playable on its day — that's what makes the comparison fair. The Yesterday & archive page shows the level codes and details of the past week, plus your best score for each day you played.
