Instructions:

This is a turn-based strategy game for two players. The game board begins as a 6x6 grid filled with frogs, half of which are red, and the other half of which are blue. One player controls the red frogs, and the other player controls the blue frogs, as indicated by the scoreboard at right.

Each turn, both players select one of their own frogs to use. Once both players have selected a frog, the two frogs act simultaneously. Both frogs act by extending their tongues in the direction they're facing. Wraparound is enabled, so a tongue can, for example, leave the right edge of the screen and re-enter on the left.

Each tongue extends as far as it can go, until it hits the other player's selected frog, the other frog's tongue, or itself (by wrapping all the way around the screen). Then, each frog brings in its tongue, eating the frog directly in front of it, and bringing any following frogs closer to it by one space. If a frog tries to eat the frog selected by the other player, it will fail. If both frogs try to eat the same frog or each other, they will both fail.

Frogs cannot change the direction they face. A frog is only allowed to act if there is another frog directly in front of it to eat. Otherwise, its lily pad will turn gray to indicate that it cannot be selected. The goal of the game is to make it so your opponent has no valid moves remaining. If only one player has valid moves left, they win. If both players run out of valid moves on the same turn, the game ends in a draw.
