Stack

One half-circle. A pile of blocks. Gravity doing its job. Stacked Cubes is a balance puzzle. Every block you drop shifts the weight of the whole tower. Put too many on one side and the base rolls over. Stack too tall and you cross the red line. Your job is to fit them all in between. HOW IT WORKS Tap a piece to rotate it. Drag it onto the base to drop it. That's the whole control scheme — no menus to learn, no tutorials to sit through beyond the first thirty seconds. Place every block the level gives you without crossing the line and without tipping over, and you move on. WHAT MAKES IT HARD The base is a half-circle, so it actually rocks. A tower that leans is a tower whose top corner rises — and the line does not move. Spreading wide keeps you low but risks the balance. Building narrow keeps you centred but sends you up. Every level is that trade-off, tightened a little further. 100 LEVELS The line drops lower. The blocks get heavier. The tolerance gets thinner. Level 1 asks for four blocks. Level 100 asks for thirty-one, on a base that barely forgives anything. QUIET BY DESIGN No ads interrupting a placement. No countdown timers. No lives to wait for. No internet connection required. Put it down mid-level and it will be exactly where you left it. Just you, the blocks, and the physics.
