Idle Spiral

This is a beautiful "Idle", "Incremental" game based on spirals and mathematics. Your goal is to make the spiral grow longer and longer. The game is very simple, but it is very deep and can be enjoyed for a long time. By buying upgrades, you can grow your spiral more efficiently. There will be a lot of mathematical equations, but don't be afraid. The upgrades themselves are not that strategic and you hardly need to understand this formula. However, as you continue to play, you will gradually come to understand the mechanics.
