About Merge Tower Defense

Merge Tower Defense puts you on a winding path where enemy waves keep coming and only smart tower placement will save the day. You build defensive turrets along the route, then drag matching towers together to merge them into stronger variants—higher level means more damage and faster shots. Between waves you can spend coins on permanent upgrades or unlock devastating active skills: flamethrowers that scorch entire groups, flying saws that carve through armor, acid pools that melt anything stepping into them, mines for surprise damage, spike traps, and screen-clearing airstrikes when things get dire. Each level ramps up the challenge with tougher enemies and longer waves, so you'll need to balance merging for power against spreading your defenses thin. If you enjoy quick tower-defense rounds with a merge-puzzle twist, Poki Games hosts this one and it's easy to lose an afternoon chasing that perfect defense setup.
