Click the menu button 'M' at the top right border to select a challenge with a fixed setup.

You are presented with a double board.
(In the default variant, click the left 7x7 board to randomly drop 49 coloured coins.)
Some of the coins will be stacked on top of each other.
You move your pieces only on the left board.
The second board displays in detail which coins are in each stack.
A stack is indicated on the left board by a thick black ring underneath the top coin.

You can pick up a stack and move 'n' steps, if it contains 'n' coins.
The lowest coin of the stack will be dropped onto the position one step away, the next onto the position two steps away and so on.

The maximum height of a stack is 10 tokens.
You lose if you try to make a stack higher than 10.

You win if either each row or each file is such that it does not contain two stacks with the same colour on top, e.g., the bottom row may have stacks with red, blue and yellow coins on top, but not two stacks with red on top.

Experts: try to create a winning setup in as few moves as possible.
All solutions have been found by hand; so you might be able to improve on them.

There are 50 variants with fixed setups.
The 6 random variants have boards 6x6, 7x7, 8x8 and two different amounts of coins dropped.

Please note that there is an alternative piece set available.
