Rise. Stack. Breathe. Zen Stack is a calm, minimalist block-stacking game about one simple thing: place with purpose. Tap to drop each block onto the tower. Time it right and the blocks line up perfectly; mistime it and the overhang is shaved away, leaving less room for the next one. The higher you climb, the faster it gets. One screen, one tap, endless focus. No clutter. No pressure. Just a quiet, satisfying climb and the soft snap of a perfect placement. GAME MODES • Classic: the original climb. A steady speed ramp that rewards rhythm and patience. • Zen: slower and more forgiving. Unwind and stack at your own pace. • Precision: fast and unforgiving. For players chasing the top of the leaderboard. Each mode has its own worldwide leaderboard, so you can master the style that suits you. PERFECT DROPS & ZEN FLOW Land a block dead-center for a PERFECT. Chain three perfects in a row to enter Zen flow, and your next three drops score double. Satisfying ripples, gentle haptics and a golden glow reward every clean placement.
