Swap adjacent blocks in order to make a horizontal or vertical row of 3 identical blocks. To complete a level you need to turn the color of all of the blocks on the board to gold. Collect more than 5 blocks to get a spell (power-up) which will show up on the right side of the screen. Cast spells by dragging and dropping it on the target. The "Hint" and "Ultra" spells are cast by clicking on them.
