Object of the Game

Setup

Each player chooses a color and places the corresponding colored indicator disc on the table in front of them so that it can be clearly seen by all players throughout the game.

This will help everyone to remember your color as your hand can contain other players' Frogs too.

Then all ten Frogs of each player's color are placed in the bag provided together with the other players' Frogs and mixed. If there are fewer than four players, any remaining Frogs are put aside and not used in that game.

Each player takes a 'hand' of two Frogs randomly from the bag and puts them next to their colored disc so that they too can be seen.

Game Play

One player starts by placing either of the two Frogs in their hand in the center of the table and taking a replacement Frog from the bag.

Play then continues in a clockwise direction. During each turn, the players must undertake the following three actions in the order shown:

1. 

   Move one of your own color Frogs that is already part of the island to another position. Frogs move by jumping to the next free space along a straight row of one or more joined Frogs.

   The Frog you choose to move may make multiple jumps in any one turn but it may not finish in the space where it started.

   If no Frogs of your own color are in play or you cannot move any of your Frogs without violating the rules, go on to the next action instead.

2. Add one of the two Frogs from your hand to the island where it touches the side of at least one other Frog. You can add Frogs of any color to the island.

   You may add your own color Frogs only to places where they are not in contact with any of your existing Frogs, but you can place your opponents' Frogs anywhere. Once all Frogs are in play, the game continues without new Frogs being added.

   If you cannot add a Frog without violating the rules or you have run out of Frogs, steps 2) and 3) can be ignored and play moves on to the next player.

3. Take a new Frog at random from the bag to replace the one you have just added to the island. Each player may have a maximum of two Frogs in their hand at any one time.

Special Rules

There are two special rules that control the structure of the island and ensure that the game is kept flowing, the one island rule a) and the string rule b):

1. 

   You may not move a Frog to a position where it would create more than one island.

   If a Frog is the only link between two or more parts of the island, the only way you may move it is to move it to a position where it re-links the island.

2. 

   You may not create a string of Frogs with three or more single connections, e.g. in the diagram on the right you may not add or move a Frog to the position marked .

Here, the only place the red Frog may be moved to is the space marked . If the red Frog is moved to any other position, it will create an illegal string with 3 or more single connections, marked in red below:

Exceptions to the String Rule

The string rule only applies to strings which end in a single Frog. If a string has multiple connections at both ends or if the Frogs form a loop,

the string can have any length.
