Slab is a one-tap stacking game. A slab slides back and forth above your tower; tap, and it drops the moment you let go. Whatever hangs over the edge gets sliced off, so your tower gets narrower — unless you nail perfect drops.
How to play Slab
- Tap to drop the sliding slab onto your tower — it falls when you let go.
- Any part that overhangs is cut off.
- Hold to slow the slab down, then release to drop it. A slowed drop can't be perfect.
- Miss the tower completely and it's game over.
Tips to get a high score
- Perfect drops snap into place — from your fourth in a row, each one grows the slab back a little.
- Watch the edge of the slab, not the middle.
- The slab speeds up as you climb; hold slows it on tricky floors, but costs you your perfect streak.
How Slab speeds up
Each new slab moves a little faster than the one before it. The speed goes up a tiny amount with every floor, with a slight random wobble from slab to slab. It keeps climbing until about floor 130, where it reaches a top speed more than four times the starting pace.
For the first 20 floors, slabs take turns coming in from the left and the right, so you always know where the next one starts. After that, about one slab in five breaks the pattern and comes from the same side twice in a row. Watch where each new slab appears instead of going on rhythm.
Perfect drops and growing back
A drop counts as perfect when the slab lands within a few pixels of the one below. It snaps into exact line, loses nothing, and adds to your PERFECT streak. Any drop that isn't perfect resets the streak to zero.
From your fourth perfect in a row, every further perfect also adds a little width back to the slab, up to the size of the base. A long streak can rebuild a tower that's got thin.
Every slab is worth one point however well you place it, so width is what keeps a run going. A wide slab gives you room for small mistakes later, when the speed makes small mistakes common.
Tap, hold and release
The slab drops when you let go, not when you touch down. While you're pressing, it slides at well under half speed, which makes lining it up easier.
But a slow drop can never be perfect. Hold for more than a split second and that slab can't score a PERFECT, even if you place it exactly. Holding is a safety move for when the speed is getting away from you, but it costs you your streak.
To keep a streak going at high speed, do quick taps and time them as the slab's edge reaches the edge of the tower below.
Don't wait too long either. The slab slides a little past the tower on each side and turns back, and after a few passes it slips off and ends your run. You'll hear a click on the last pass, so drop it then. Dropping it completely off the tower ends the run too.

FAQ
What does a perfect drop do?
Landing a slab almost exactly on the one below snaps it perfectly into place. Four or more perfects in a row make your slab grow back a little.
Is it free?
Yes. Every Tapamine game is free to play in your browser with no download and no account.
Does it work on my phone?
Yes. Tapamine is built for phones first: portrait, one thumb, and it works offline after your first visit. It also works with a mouse or the spacebar on a computer.
How do challenges work?
After a run, tap “Challenge a friend” to send a link. Your friend plays the exact same level and races your ghost — a replay of your run — to see who wins.
