Looking for a puzzle that calms you down and keeps your brain spinning? Cat Sudoku! is a pure logic game where every aloof little cat needs a spot of its own. The rules are simple, the deduction runs deep: place exactly one cat in each colored region — never in the same row or column, and never touching another cat, not even diagonally. Read the board, mark impossible squares with a cross, and reason your way to the one arrangement that works. A gentle tutorial eases you in, 10,000+ levels and an endless mode keep the challenge coming, and a fresh Daily Challenge lands every day. No numbers, no internet required — just you, the cats, and a quiet moment of focus, anywhere you go.

The rules are simple: tap anywhere to shift your shape, and match the falling geometry before impact. One wrong tap means Game Over. Features: Pure One-Tap Gameplay: Playable anywhere, anytime. Tap the screen to seamlessly cycle your shape. Dynamic Gravity: React instantly as shapes unpredictably plummet like stones or float like feathers. The Fake-Out: Stay alert! Falling shapes can trick you and morph mid-air. Risk vs. Reward: Shift at the exact last millisecond before impact to score a "Perfect!" +3 point bonus. Satisfying Visuals: Experience striking minimalist aesthetics with responsive haptics and neon particle explosions. Chase the High Score: Compete against your own reflexes to beat your all-time best score. How long can you survive the shift?
