About the game

A base, a stream of enemies, and a pile of tanks that are weak until you pair them off. That is the whole setup in Defender: Tanks Merge, and the waves get heavier fast, so a sloppy lineup falls apart.

Between waves you tidy the board, ditch tanks you do not need, and let auto-merge handle the repetitive pairing. Bombs and mines are your panic buttons. The mine rule is the annoying part: you cannot drop one next to your own tanks, so the spot has to be decided early.

How to play

Pull a tank across the board and release it on a matching one to upgrade it. Unwanted tanks go into the trash can.
Hit an ability button, then pick the area to target. Tap any ability button or the base area to back out.
Mines are blocked near your tanks, so leave room for them before the wave arrives.
