Spiral Defense - Strategy Game
About this game
Spiral Defense bends the tower defense map into a coil. Enemies ride a spiral track that tightens toward your core, and your towers sit on three concentric rings of pads: inner pads cost more but cover the whole spiral, outer pads are cheap but blind on the far arcs. Open new pads as the economy allows and pick from five towers — pulse, frost, beam, nova and sniper. Orbiters drift and stall, blinkers teleport forward, and every fifth wave a boss grinds down the coil. Every kill closer to the core pays extra — risk is reward here.
How to play
Tap a pad to unlock or build, choose a tower and upgrade as gold allows. Enemies follow the spiral to the core — hold the shield above zero for as long as you can.
Tips & Tricks
- Inner pads cover the entire spiral — one strong tower there outperforms three outside.
- Sniper towers love the middle ring — full range without the inner price tag.
- Orbiters linger on their loop — frost towers turn that into free damage.
- Kills near the core score up to triple — letting a weak enemy slip inward is a gamble.
Frequently asked questions
Why do outer pads cost less in Spiral Defense?
The spiral only passes through part of each outer arc, so outer towers have blind spots. Cheaper pads, partial coverage — that is the core trade of the game.
How does scoring work in Spiral Defense?
Kills score more the deeper they happen — up to nearly triple near the core. Clearing a wave adds its number times one hundred.
