Play this match 3 and tower defense hybrid and see how many waves of enemies you can outlast. Touch and drag the blocks to swap them, creating matches. When blocks are matched, a turret is created that can fire at the enemies that move close to them. Turrets also have two stages, and matching stage one turrets will create stage two turrets for more damage to enemies. After each wave, you will get a free move that will let you swap any two blocks even if those blocks do not result in a match. Try to match as much as you can and see how long you can last.
There are four turrets in the game. The yellow one is a standard shooting turret with a normal fire rate. The green one is a turret that shoots more slowly but does more damage than the yellow turret. The blue one fires a bullet that slows down the enemy that it hits. The red one can hit multiple targets with lasers.
