How to play
- Select an empty numbered pad beside the sandstone road, then choose a tower. Start with a Cannon near a bend for longer coverage.
- Read the next-wave preview before sending enemies. Cannons damage clusters, Frost slows fast runners and Prisms ignore armor.
- Earn gold by stopping enemies and completing waves. Upgrade a tower for more damage and range, or sell it for 70% of its total cost.
- Select a built tower and change Target to First for the enemy nearest the exit, or Strong for the toughest enemy in range. Tie-breaking still favors the nearest exit.
- You can build during a wave. Runners cost one crystal health if they escape; armored beetles cost two and wardens cost four.
- Clear every wave with health remaining to unlock the next mission. Finish with 15 health for three stars or at least 10 for two.
- Progress saves between waves on this browser when storage is available. Leaving mid-wave returns to the previous planning checkpoint. Saves can be lost if browser data is cleared.
- Use 1x speed to plan carefully or switch to 2x. This is solo play; there are no online opponents or public rankings.

Citadel Routes tips and strategy
- Place towers where enemies stay in range for more of the route. Check coverage around bends before spending resources on a position that fires only briefly.
- Balance new coverage with upgrades to an existing tower. Read the next wave and the route you are defending instead of buying the same tower arrangement for every map.
