Idle Spiral

What is Idle Spiral? This is a beautiful "placed class", "incremental" game with a spiral and math theme. Your goal is to make the spiral longer and longer. The game is very simple, but rich in content and high in playability. How to play? Grow your spiral more efficiently by buying upgrades. The game will contain many mathematical formulas, but don't worry. The upgrade itself doesn't require much strategy, and you hardly need to understand the formulas. However, as the game progresses, you will gradually understand the game mechanics. The progressive prestige mechanism game has a variety of "prestige" (like many placement games!) the reset mechanism. Reputation resets most of the game's progress, but allows you to make longer-term progress faster than before. Battle Spiral In Battle Spiral, your spiral will be used as a weapon to fight with various spiral designs; in order to gain an advantage in Battle Spiral, it is important to consider which rewards to choose and in what order to fight the enemy. Challenging Challenges are designed to achieve specific goals within tough constraints. In a challenge, you will be faced with deductions, restrictions, and changes to the underlying gameplay while trying to achieve a goal. After completing the challenge, you will receive a great reward. The endless content tornado prestige is just the beginning part of the game. Although it will take some time to clear the customs, there is more waiting for you! Music produced by AKIYAMA HIROKAZU from H/MIX GALLERY
