- The objective of the game is to swap one tile with an adjacent tile to form a horizontal or vertical chain of three or more tiles.
- Matched tiles change into a lighting shot to attack enemies. Horizontal tiles attack the right side enemy. Vertical tiles attack the bottom side enemy.
- You complete the level if all enemies are wiped out.
- You fail the level if your HP becomes 0 or time runs out.
- Vertical tiles increase the Shield Point instead if there is no target of attack. HP does not decrease until the Shield Point becomes 0.
- Horizontal tiles increase the Homing Point instead if there is no target of attack. When the Homing Point is filled up, the homing attack works for 30 seconds.
- The attack power increases if you match next tiles before the attack animation finishes. The more you do this attack, the more the attack power increases.
