Merge Defense

Merge × Tower Defense!

Merge matching allies to evolve them into stronger monsters, then deploy your team and defend your castle from waves of enemies!

The rules are simple:

Merge → Deploy → Defend

Combine allies of the same type and rank to make them stronger.
Deploy weaker units quickly, or keep merging to create powerful monsters — the choice is yours.

At Rank 3 and above, the Merge Gamble can appear.
Play it safe for a guaranteed upgrade, or take a risk for a huge rank boost!

Collect unique monsters, use powerful skills like Bomb Rain and Freeze, and build your strongest team.

Battle through 16 areas and 80 stages, defeat powerful bosses, and reach the Final Void!
