Stack Tower 3D

🎯How to play

1. 1A block slides back and forth across the top of the tower. Click, press space or enter, or tap the screen on mobile to drop it right where it is.
2. 2Only the part that overlaps the block below stays; the overhang is sliced off and falls, so aim for the moment the two line up.
3. 3Floors stack on alternating X and Z axes, and the block moves faster the higher you climb.
4. 4Each block you place adds to your score, and a near-exact drop counts as a 'perfect' that awards bonus points.
5. 5If a block has no overlap at all with the floor below, the tower topples and the run ends. Your score is saved as your best.

💡Tips

• ›When the overlap is within about 5 percent of a clean match, you score a perfect: nothing gets cut, so the tower keeps its full width.
• ›Chaining perfects builds a combo that raises the points per drop up to +6, so the real goal is to never break your accuracy streak.
• ›Once your combo reaches 5, a block that had shrunk starts widening again, so a narrow tower can recover through steady perfects.
• ›As the speed ramps up, watch the block cross center and tap a hair early to compensate for reaction time and avoid a full miss.
