About
Your fortress is the last thing standing.
Set up your towers, spend your gold wisely, and keep the monsters away from the gate. Tower Fortress: Idle Defense is built for quick sessions, steady upgrades, and that satisfying feeling of coming back stronger every time you play.
Send each run a little farther:
- Build a compact defense that keeps fighting
- Upgrade tower power, resources, and long-term bonuses
- Face monster waves, tougher enemies, and boss attacks
- Collect idle rewards when you return
- Play comfortably in short one-hand sessions
Hold the line, improve your setup, and see how long your fortress can last.
