Block Stack is a physics stacking game with one rule: don't let anything fall. Drag blocks from the dock, drop them onto your tower, and stack as high as you can. REAL PHYSICS, REAL TENSION Every block obeys gravity, friction, and momentum. No grids, no snap-to guides — just you, the blocks, and the laws of physics. A careless placement can send your entire tower into a slow, agonizing lean. THE GAME THAT LEARNS HOW YOU PLAY An adaptive algorithm watches your tower — scanning its shape, measuring its tilt, tracking how well you play — and designs each round to match your skill level in real time. You'll never notice it working. You'll just feel like every round matters. 28 BLOCK SHAPES, 3 TIERS OF CHALLENGE Start with simple squares and dominoes. As your tower grows, L-shapes and trominos enter the mix. Push past 30 blocks high and face S-pieces, Z-pieces, T-pieces, and the dreaded I-bar. FEATURES - One-handed portrait play — perfect for commutes and queues - Haptic feedback on every placement - Smooth camera that follows your tower as it climbs - Background shifts from park green to deep space as you ascend - Auto-save when you leave - No ads. No in-app purchases. No data collection.
Stack Em

Stack Em! is a simple, addictive block-stacking game. Tap to drop blocks and build the tallest tower you can — but be careful, one wrong move and it all comes crashing down.

Features: - Easy to pick up, hard to put down - Perfect placement bonus scoring - Satisfying physics and haptic feedback - Compete against your own high score How high can you stack?

Verdict
The clearest difference is ads: Block Stack at none against Stack Em's shown. Block Stack also leads on iOS requirement (16.0 vs 18.2). On price, in-app purchases and device support there is nothing between them.
