Can you cut a shape exactly in half? Impossible 50 is a precision puzzle game where your goal is simple: draw one line and split each shape as close to 50/50 as possible. It sounds easy. It is not. Every level gives you a new 2D shape. You draw a single slice, then the game measures how close your cut is to a perfect half. The closer you get to 50/50, the better your score. Start with simple shapes. Then face harder objects, abstract forms, animals, letters, and symbols where the perfect line is not obvious. Features - Draw one line to cut each shape - Try to split every object exactly 50/50 - 150 handcrafted levels - Multiple worlds, including shapes, abstract objects, animals, letters, and symbols - Precision-based scoring - Star rating system - Daily challenge with a new shape - Replay levels to improve your score - Clean 2D design - No timers, no pressure Impossible 50 is made for players who enjoy simple puzzle games, line drawing games, geometry puzzles, and accuracy challenges. The rule is simple: Cut it in half. Exactly.
