Six Sides is a minimalist hex-grid puzzle game built on one elegant rule: every numbered token must touch exactly that many neighbors. Place, drag, and rearrange pieces on the board until every token turns green. Simple to learn, deeply satisfying to master. Work through 42 handcrafted levels that introduce new constraints step by step, then unlock Endless Mode for unlimited, randomly generated challenges that never repeat. Whether you have two minutes or two hours, Six Sides fits your pace. FEATURES - 42 hand-designed logic puzzles with increasing complexity - Endless Mode: infinite auto-generated levels - Real-time color feedback as you solve (yellow, red, green) - Locked tokens that add extra constraints - Clean, minimal design with smooth animations - No timers, no pressure, no clutter - Accessible for beginners, rewarding for experts HOW TO PLAY Each token shows a number. That number tells you how many adjacent tokens it needs. Too few neighbors and the token turns yellow. Too many and it turns red. When a token has exactly the right count, it turns green. Solve the puzzle by turning every token green. Tap, drag, and rearrange until everything clicks into place. FOR PUZZLE LOVERS If you enjoy Sudoku, nonograms, tangrams, or spatial reasoning games, Six Sides offers the same calm focus with a fresh mechanic. Logic, spatial planning, and pattern recognition come together in a system that is easy to understand but hard to put down.
