Idle Spiral
Released Apr 2022
This is a beautiful "Idle", "Incremental" game based on spirals and mathematics. Your goal is to make the spiral grow farther and farther from the origin. The game is very simple, but it is very deep and can be enjoyed for a long time!

Idle Spiral is a free-to-play idle/incremental game that launched on April 30, 2022 and has been in continuous active development since. On August 27, 2026 — today — the developer published a "Full Release" announcement marking the graduation of the long-running v3.0 update (which had been in public beta since August 4, 2026) to the default branch for all players. This release includes the largest content update the developer has ever shipped: a new endgame feature called Hanoi Tower, major UI redesigns, a new save infrastructure, cross-platform account linking, and more.
Crucially, the same August 27 post explicitly announces what comes next. The developer has committed to two named upcoming features: a **Season System**, described as a competitive prestige-style mode where all players start on equal footing and runs are measured against a shared leaderboard — designed to restore challenge for players who have "finished" the core game — and something called **Design Fusion**, which the developer has teased by name but is not yet ready to detail. The post also confirms that steady UI improvements will continue as an ongoing maintenance commitment.
All eleven DLC packs currently listed on the store have been released. The game has a long history of feature patches and major content additions stretching back to 2022, and the developer is visibly engaged: multiple patches shipped during the August 2026 beta period alone (v3.0.7, v3.0.11, v3.0.18, v3.0.22). With specific future content named and developer communication happening today, this game is clearly continuing to grow.
Evidence
Developer announces full release of v3.0, and explicitly names two upcoming features: a Season System (competitive prestige-style mode with shared leaderboards) and Design Fusion (details withheld, 'more when it is ready'). Ongoing UI maintenance also promised.
Public opt-in beta opened for the next major version, introducing Hanoi Tower, UI redesigns, new save infrastructure, Google account linking, and the Idle Mileage system.

About this game
What's 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.
How to play 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.
Layered prestige mechanics The game has various reset mechanisms called Prestige (as seen in many Idle games!). Prestige resets much of the game's progression, but allow you to progress further and faster than before.
Battle Spiral In Battle Spiral, your spiral is used as a weapon to fight various designs of spirals; to gain an advantage in Battle Spiral, it is important to consider what rewards to choose and in what order to fight the enemies. An extremely powerful boss with a very complex shape awaits you in the second half of the game!
Challenges Challenges aim to achieve a specific goal under strong constraints. In challenges you will face debuffs, constraints, and fundamental gameplay changes while trying to achieve a certain goal. After reaching the goal, the challenge is completed and you receive big rewards.
Endless Content Tornado Prestige is just the beginning of this game. It will take some time to progress through the game, but more content is waiting for you!
