Start by making a coin active by clicking
on dice dots of its colour.
This coin will use the dots to move
but also to push others towards the exit.
A move or a push is done by clicking
on the new destination of the coin.
To move the active coin you must
choose a direction (down, up, right,
left or diagonal) which must be identical
until the die is changed.
To push a coin, the active coin must be
next to it and use its dots for pushing.
In this situation the direction is the line
formed by the two coins.
A square is equivalent to one dot, passing
on an occupied square is not allowed.
