You are given a setup containing an equal number of red, yellow and blue tokens which sit on yellow, blue and red squares. Your task is to swap the positions of tokens such that each token sits on the target square of its own colour.

You can only move pairs of tokens, and only into the direction of their alignment. When you move a token north, for example, its southern neighbour will also be transported as if it would be glued to the other token.

Some variants have black no-go areas (walls).
You cannot move any token onto a wall or over a wall.

Beginner:
You win when you have swapped all tokens.
Expert:
Use only as many moves as given at the top border.
There is also a counter showing the number of moves you have played.
