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.
Additionally (to speed the game up), a stack consisting of a single coin can move any distance.

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

You win if each stack is monochrome, e.g., each stack contains only coins of one type of colour.

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.
Some of the random setups might not be solvable.

Please note that there is an alternative piece set available.

 
Technical information:
Games with mixed Stacks of pieces on board positions are notoriously hard to encode in Zillions, because Zillions allows only one piece per board position. The dual-board method I originally invented for the game 'Laska' solves this problem.
