Classic puzzle - can you switch the red and blue frogs?
The objective is to move the red frogs to the right and the blue frogs to the left. You move the frogs by jumping another frog or moving one space to an empty hole. Blue frogs can only move left and red frogs can only move right.
A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
