Puzzle Deep is built around deduction. Every puzzle is checked by a solver that only uses logic, so the answer is unique and never needs a guess. Hints name the technique to look for, every level shows a par, and the last 30 levels of each game are Expert dives. Collect 54 Bronze, Silver and Gold seals in your Dive Log along the way.
