The player`s task is to persuade the members of the frog colony (who are sitting on the rock) to jump into the waving water which is just in front of them. This may be achieved by completing series of steps according to the rules of the game. It counts as a regular step, if the player (with the chosen frog) reaches a rock by jumping over a rock or a frog which is next to him. Whether a step is regular or not is shown by the colour of the cursor (red) and the line showing the arc of jumping (green). Each member of the colony has a number above its head: 1, 2 or 3, which shows how many times the small amphibian should be jumped over before leaping into the water.
