Each level consists of a tiled playing field covered in colored runes. Using the mouse, click runes and drag them to swap with adjacent runes in order to make sets of three or more. These runes can be aligned vertically or horizontally. When you make matches, the runes disappear and any tiles behind those runes break into bricks which are carried up to the workers above. When four runes are matched, an Ice Ball power-up is created. Swapping this power-up with any adjacent rune will activate it and clear all runes in a row. When five or more runes are matched, a Fire Ball power-up is created. Activating this will clear all runes in a row and column. Activating several power-ups will create a Dice Bonus. Swapping a Dice Bonus with an adjacent rune will randomly remove several runes from the board.
