About Circle TD
Circle TD turns a closed road into a growing tactical problem. Enemies that complete another lap gain corruption and increase the circuit’s load, so tower placement matters as much as raw damage. Choose a twelve-chapter campaign, a sixty-round classic run, endless defense or the daily challenge. Upgrade gemstone towers, consider specializations and relics, and prepare for the upcoming waves. Play alone or configure up to four local seats with hot-seat players and AI allies. Runs, records and progress stay in this browser; this standalone release has no online multiplayer or cloud save adapter.
How to play
Choose a mode, map, difficulty and team seats. Select a tower and place it away from the road. Call the next wave when your defense is ready, then upgrade towers and use abilities to manage the enemies. Each completed lap makes enemies more corrupt and increases circuit load. Pause when needed and use Continue run when returning to the same browser.
Rules in this version
- Build towers on free ground away from the road.
- Enemies gain corruption and increase load when completing laps.
- Classic mode has sixty rounds; endless mode has no preset final round.
- Team members share the circuit but have separate gold and towers.
- Local progress does not sync across domains or devices.
Tips for playing
- Build within range of the road; an isolated central tower may not reach the enemies.
- Check upcoming waves before spending all your gold.
- Combine damage types and effects rather than relying on one tower.
- Pause to review upgrades and resume your defense.
Questions about this game
Can I resume a run?
Yes. Return to the same browser and domain with storage allowed and choose Continue run.
How does team play work?
Configure up to four seats with hot-seat human players and AI allies on the same screen. This is not online multiplayer.
What happens after another lap?
Enemies gain corruption and add circuit load. Eliminate them before that pressure overwhelms your defense.
