Fragile Balance is a physics-based block stacking game where you drop bricks one by one onto a narrow, tipping platform and try to keep everything from toppling over. Each block shifts the weight distribution, so every placement matters. Stack too many on one side and the whole tower crashes down. Simple concept, brutal execution. The game runs directly in your browser with zero downloads required, making it easy to jump in for a quick session or grind for a personal best. What makes Fragile Balance genuinely tricky is the platform itself — it pivots and sways with each new block, so you can't just pile bricks in the center and call it done. You need to think a move or two ahead, compensating for tilt before it gets out of hand. The minimalist visuals keep the focus entirely on the physics, and that satisfying crumble when your tower finally goes is equal parts frustrating and addictive. Players who enjoy casual skill games, patience-testing puzzles, and physics sandbox challenges will feel right at home here. Whether you're looking for a free block building game, an online balancing game for mobile, or a casual one-player arcade game to kill time, Fragile Balance delivers a clean, satisfying challenge that's easy to learn but hard to master.
