Tower Defense — Genre Overview

Tower defense is one of the few genres that translates perfectly to mobile touch without losing anything — tap to place, tap to upgrade, the geometry of the map does the rest. The problem is that most free browser TD games add energy timers or pay-to-speed-up mechanics that break the loop. The titles Bramwell's test-rig returns consistently are the ones with fixed content and no energy: Bloons TD 5, Kingdom Rush Frontiers (first world only on free version), and the increasingly-hard-to-find Desktop Tower Defense.

Session Length

20–60 minutes typical.
