Royal Triple Defense

Merge-based tower defense

Royal Triple Defense is a PC tower defense game about holding a bridge between a town and a battlefield. You build your army on a shared board: group three matching pieces to merge them into one of the next rank, or group four to create a crowned unit. There’s no barracks, and the board handles both army-building and money-making.

Coins come from merging too. That means building up your forces and earning gold draw on the same resource, so each merge changes what you can spend or field. You need to hold the bridge through the nights until dawn.
