About this game

How high can you stack? Tap at the right moment, line up the blocks, and watch your tower rise — one satisfying drop at a time.

Istif (Turkish for "stacking things up neatly") is built around a single rule: perfect timing wins. Anyone can pick it up in seconds, but beating your best takes real focus.

HOW TO PLAY
- Tap anywhere to drop the moving block
- Line it up with the block below to keep your tower solid
- Miss the edge and the overhang gets sliced off — your tower gets narrower
- Land a PERFECT drop to keep the full width
- Chain 3 or more perfect drops in a row and your block grows back wider!

WHY YOU'LL LIKE IT
- Perfect streaks let you rescue a shrinking tower — every run has a comeback
- Colors shift as your tower rises, so every run looks a little different
- One-tap controls, short rounds — perfect for a quick break
- Missed a block? Get a second chance with an optional short ad, once per run
- Your best score is always saved, so there's always something to chase
- Share your best runs with friends and see who climbs higher

Simple to learn, tough to master. Open Istif and see how high your tower can go.
Tap to stack, chain perfect drops to grow your tower. How high can you go?
