Defend the Castle

Defend the Castle is a fast-paced tower-defense card game where you build and customize tower card decks to protect your fortress. Collect elemental tower cards, combine and fuse them to create stronger defenses, and level up towers to face increasingly powerful waves, elite enemies, and boss battles.

Play solo through escalating challenges and timed quests or go head-to-head in PvP to deploy minions and counter enemy attacks. Join or create alliances to coordinate defenses and tackle cooperative events. Free to download with optional in-app purchases; network connection and a minimum age requirement apply.
