About Goishi: Black & White Puzzle

Connect black and white—each in a single, unbroken area. Goishi is a logic puzzle where you shade every cell black or white. Just three rules, endless depth. THREE SIMPLE RULES - Shade every cell black or white. - All black cells connect; all white cells connect. - No 2×2 square may be a single color. Every puzzle has exactly one solution—reached by reasoning, not guessing. HINTS THAT SHOW WHY When you're stuck, Goishi reveals the next forced cell and the reason: "fixed by the 2×2 rule" or "fixed to keep a color connected." You stop guessing and start seeing. It's the satisfaction of understanding, not just finishing. FOUR LEVELS + A DAILY PUZZLE - From Easy (6×6) up to Expert (12×12). - A fresh Daily puzzle every day, with a running streak. - Puzzles are generated on device, so boards rarely repeat—and the twistier they get, the more rewarding the connections. QUIET AND BEAUTIFUL Go…
