One vs Stack and Shatter

Draw each figure with a single line without lifting your finger from the screen. Train and improve your visual agility, logic and reasoning skills. There are 150 levels, can you solve them all?

Stack & Shatter is a precision stacking game where every placement counts. Drop blocks onto a growing tower with pixel-perfect timing. Land them cleanly to build combos that multiply your score — but watch out. Each consecutive combo speeds up the blocks, pushing your reflexes to the limit. The higher your combo streak, the bigger the risk and the bigger the reward. Miss your mark and the block gets trimmed. Miss it entirely and your tower comes crashing down. COMBO RISK/REWARD SYSTEM String together perfect placements to trigger score multipliers up to 10x. But every combo also increases block speed up to 2x, creating a thrilling push-your-luck dynamic. Do you cash in your safe score or chase the massive multiplier? 100 LEVELS ACROSS 10 ZONES Climb from the Ground Floor through the Skyline, past the Stratosphere, and into the Singularity. Each zone introduces faster speeds, tighter margins, and boss levels that demand peak precision. The tower gets taller. The blocks get faster. The stakes get higher. SATISFYING EFFECTS Spark bursts, shockwave rings, star showers, electric arcs, and screen flashes escalate with your combo streak. Every perfect placement feels incredible with synchronized haptic feedback that intensifies as your combo grows.
