How to play Block Stack
A block slides left and right above your tower. Tap, click, or press Spacebar at the right moment to drop it. The overlapping portion becomes your new platform — the hanging part tumbles off. Miss completely and it's game over. Stack precisely to keep your platform wide.
Every 5 floors the crane switches cargo and the rules change. Lunch Break bento boxes slide faster and are narrower. Overtime coworkers follow an unpredictable sine-wave roll. Night Shift neon signs flicker randomly. Graveyard crates arrive in random sizes. Survive all 6 shifts and you enter Chaos Mode — anything goes.
Land within 3% of perfect alignment for a PERFECT! bonus — your platform stays the same width and your combo counter grows. Chain 5 perfects and your block glows gold. Your best floor is saved on this device.
