Idle Spiral

Idle Spiral is an incremental game about growing a spiral longer and longer. You buy upgrades to increase its growth, with mathematical equations underpinning the mechanics. The upgrades require little strategic planning, and you can gradually learn how the mechanics work as you play.

Upgrades and prestige

Prestige mechanics let you reset much of your progress in exchange for the ability to advance further and faster. Tornado Prestige is one of the game's reset systems.

Battle Spiral

In Battle Spiral, you use your spiral as a weapon against other spiral designs. Choosing rewards and the order in which you fight enemies can help you gain an advantage. A powerful boss with a complex shape appears in the second half of the game.

Challenges

Challenges set a specific goal and impose constraints, debuffs or fundamental changes to the gameplay. Completing a goal finishes the challenge and earns you substantial rewards. Further content awaits beyond Tornado Prestige.
