Froggrid is a logic puzzle where you place one frog in every row, column, and colored region of the board. Frogs cannot touch each other, including diagonally.
Players use those rules to eliminate impossible spaces and determine where each frog must go. Puzzles range from 5×5 to 12×12 and come in Easy, Medium, and Hard difficulties. Every puzzle is intended to be solved through deduction without guessing.
Hints are available if you get stuck, and the game can be played offline without an account. Signing in allows you to compete on leaderboards.
