Zoduko is a symbol-based logic puzzle built around pure deduction. Instead of numbers, Zoduko uses a distinctive set of symbols. Every row, column, and region must contain each symbol exactly once. No math required. Just logic. THREE WAYS TO PLAY Classic Settle in and solve at your own pace. Read the board, find what must be true, and work your way toward the final symbol. Daily A fresh puzzle every day. One board, one challenge, and another reason to come back tomorrow. Entropy Zoduko’s signature mode changes the rules. The puzzle itself is unstable.
