Rules
=====
Clear the board by finding two items with identical symbols. The tiles will disappear when you can 'connect' them with a line, which has two or less corners ( right angles ) in it and no other part is blocking the way. Advance to the next level by clearing the board. If you run out of time before you finish a map, you lose.
A map can contain tiles in up to 3 layers. You might combine tiles of different layers. If you pick one tile from the top layer and one from the bottom layer, only tiles on the top layer block the way, for example.
In general: if you pick items from different layers, the upper most selected items layer is used for the search algorithm. Sounds difficult but if you give it a try, you will figure in no time... ;)
Tiles with the same symbol might be located on top of each other. So the fastest pick is not always the best.

Bonus Level
===========
After each 3 solved levels a bonus level appears. Three different kinds of
bonus level exists:
1. Start with 4 tiles and fill up the map. Every time you remove a pair, 4 new tiles will appear. Manage to fill up the whole map.
2. The play field contains covered items. Select two items to uncover. If the symbols match, the items disappear, if they don't match the item hides again. Try to remember the item and position.
3. The play field contains covered items. Two identical items will appear quickly at different position. Try to remember the last position and select the two items.
In case time runs out, you advance to the next level. After finishing a bonus level you receive an extra Hint-Item ( see below ) and 100 extra bonus points.

Battle Mode
===========
Each player has to finish his move within 6 seconds. If a pair was found or 6 seconds elapse, the play field flips and it is the others player turn. The duration of the game is 3 minutes and can be extended by the 'Time Bonus Item' ( see below ). The game ends when the time runs out or there are no possible moves left.
