You are given a setup containing a number of red, yellow and blue tokens; The token can have various shapes: star, circle, square, triangle, hexagon, cross and inverted triangle.

Your task is to swap the positions of tokens such that the colour of each token conforms to the colour scheme given at the right half of the board.

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.
There is an additional complication, however: The two tokens may not have the same shape!

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

Beginner:
You get a win-message when the colurs of the tokens conform to the given setup.
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.

Solutions are attached (click Help/ShowSolution).
All solutions have been found by hand; so maybe you can even improve on them.

Random variants:
Two variants with random setups are included.
Click an empty position first to randomize the setup.
It seems that all random setups presented in this game have a solution.

Please note that there is an alternative piece set available.

 
Again the Doshu-puzzles surprise by their simple setups and complex solutions.
Doshu III with only 9 pieces in any of its fixed variants is definitely an extremely minimalistic puzzle game. Nonetheless it is very hard to find the shortest solutions, are any solution for that matter.
