Stack, Balance, Collapse. An Addictive Minimalist Physics Puzzle! Tsumi Stack is a minimalist physics-based stacking puzzle game . While the rules are simple enough for anyone to jump right in, the unique mechanic where "three touching blocks of the same color vanish" demands deep strategy and a keen sense of balance . The controls are incredibly simple, but the shifts in the center of gravity caused by unexpected erasures, combined with realistic gravity and friction, bring heart-pounding tension and drama to your every move. 🧩 Game Features The Thrill and Satisfaction of Realistic Physics: With a wide variety of block shapes, even a single millimeter of misalignment can shift the entire center of gravity. This realistic physics simulation creates unpredictable tension, delivering a deeply satisfying sense of accomplishment when you achieve the perfect stack. Strategic Color Placement to Avoid "Erasure": When three blocks of the same color touch, they instantly vanish! Beyond just stacking high, you must carefully plan your dropping sequence and placement strategy to prevent sudden erasures from breaking the tower's balance in this intellectual battle of thinking one step ahead. No Time Limits! Relax and Play at Your Own Pace: There are absolutely no timers to rush you. You can take all the time you need to carefully plan your next move. Push the Limits & Conquer the Leaderboard : The higher you build, the more the tower sways as if caught in a gust of wind.
