- v3.0.71 - 5 October 2026
- Fixed the Challenge menu opening the Battle Spiral instead of the challenge list.
- v3.0.70 - 4 October 2026
- New raid tower: Dynamics, the sixth Hanoi tower. Clear Topology to unlock it. It is the first tower built six HP layers deep instead of five. - The ×10 buy button now prices what pressing it will actually buy. When ten levels are out of reach it reads "+3 / 10" and buys those three, instead of refusing the purchase. - ω automation after a Tornado no longer replays the spiral transition and writes the save every second. Which ω tiers are taken, and when, is unchanged. - Fortitude now shows your streak against its target, says whether the current difficulty qualifies, and tells you when a fall put the count back to zero. - Auto Start no longer runs during Fortitude. It was resetting the difficulty every tick, which could make the 100,000 condition impossible to meet again. - Drain now shows r and how much it loses each second. Its reduction is no longer multiplied by Loot, Tornado and R…
- v3.0.69 - 2 October 2026
- Saves that refused to open the game now open: an automation list longer than the build knew about, an unexpected battle item count, a design the build no longer has. Nothing on disk is rewritten by a refusal. - Fixed Steam failing to initialise on some machines, which stopped the game before the title screen. - The 3D (Z-axis) view buttons work again. - Twelve new Tornado unlocks between T131 and T250 — higher Battle Upgrade caps, higher n and u limits, larger automatic purchases. The ladder now runs past T225. - Buy ×10 and ×25 now price the levels they actually buy, stop at the row's maximum level, and buy all of them or none. The shortfall is shown when you cannot afford them. Max is unchanged. - Automatic purchase no longer buys rows that are still locked. - Every battle reward says what it is and what it feeds. - The battle reward breakdown reads "gained → effect" with the effect…
- v3.0.66 - 1 October 2026
- Fixed four kinds of save that refused to start the game: a battle-item list of an unexpected length, a design this build no longer has, an array left empty beside a filled one, and a machine without the Discord library. Everything readable is kept in its original order, and a refused save is never rewritten on disk. - Fixed a damaged reset record stopping both startup and saving. The game now starts from the newest save that passes its checks and rebuilds the record around it. - Hard Reset now marks the old save as superseded, so a save from years ago can no longer be migrated back in at a later update. - Every battle reward you hold is now listed, including ones that had never appeared on any screen: f, g, a₂–g₂, a₃–g₃, HP₂, ATK₂, DEF₂, attack speed ₃, γ₂ and Rare Drop Rate ₂. - Layered rewards now show what they multiply (a₂ → a) and their own amount, instead of repeating the total…
- v3.0.61 - 27 September 2026
- Buying an upgrade no longer resets the spiral. Length is the currency, so a purchase spends it and since v3.0.42 that was being mistaken for the drawn spiral having gone stale, so the whole shape was cleared and a new spiral started growing every time. Now the spiral folds at the point you bought, keeps growing from there, and the bends accumulate into the figure they were always meant to build. - The spiral tip no longer flickers. For one frame after each vertex was committed the tip had no direction to face and snapped flat. Early in a run that landed roughly once a second; it faded as the spiral grew longer.
- v3.0.45 - 11 September 2026
- Extended the Tornado unlock progression through T225. - Added exponent upgrades for a–g to the p tab, including the previously inactive T99 upgrade for a. - Added Z-Reactor EX_C at T98, which strengthens the exponent of c and features an intricate, braided flower-like curve. - Added Z-Reactor EX_L2 at T200, which accelerates Loot progress and features a woven spherical curve. - Added six new Professor Challenges: - Sinkhole — T92 - Sphere — T102 - Drunk — T111 - Poor Math — T119 - No Rebirth — T150 - Sin Spiral — T225 - Each new Professor Challenge features 11 completion levels with progressively harder goals designed for long-term progression. - Added a per-clear cap to Professor Poor Math’s reward to prevent excessive scaling with extremely large parameters. The original Poor Math challenge is unchanged. - Added Tornado-based access to additional Battle Upgrade groups at T90 and T10…
- v3.0.45 - 6 September 2026
- Improved main spiral rendering performance. The spiral recalculated its screen mapping once for every point on the curve; it now does this once per frame. Sessions with many visible curves should be noticeably smoother. - The game now runs at a reduced frame rate while in the background, and returns to your chosen rate as soon as the window is focused again. The frame rate is checked continuously rather than relying on a single notification, so the game cannot get stuck at the reduced rate. - Added a frame rate and a spiral refresh rate setting so you can choose how much of your machine the game uses. - Added a Fit button to the menu bar that reframes the main spiral to the current curve. - Main Spiral Scale now follows a growing distance at a usable speed. It was easing so slowly that the view could lag far behind the spiral it was meant to be tracking. - Create Backup now works when…
- v3.0.43 - 5 September 2026
- Moved SAVE & QUIT to a fixed position at the bottom of Settings. A confirmation now appears before quitting without saving. - Improved recovery for some older PC saves by using a valid automatic save when legacy local data is incomplete. - Fixed the z-based Δr bonus decreasing after spending z on upgrades. - Fixed n, u, v, m, α, and β upgrade effects sometimes updating one purchase late. - Fixed Auto Start rerolling the current reward board. It now preserves the board while resetting battle difficulty. - Fixed spiral design changes overriding the Pixelize setting. - Auto P Prestige now plays the same transition as a manual Prestige. - Fixed Main Spiral framing and oversized old geometry after spending r, using P Prestige, starting a Challenge, or re- enabling Scale.
- v3.0.35 - 30 August 2026
Added a DLC tab to the Store with clearer Q.E.D. Pack ownership status and actions. Saved unlock and selection states are preserved while Steam is unavailable.Separated Daily Bonus and Daily Spiral into dedicated tabs, making remaining spins, reset time, and rewards easier to check.Daily Pack owners now receive five spins per day and 1.5x Spiral Point rewards from Daily Spiral. Players without the pack receive three spins per day.Fixed Critical Damage and Super Critical Damage reward percentages to match their actual effects. Balance remains unchanged.Added support for recognized legacy PC saves containing 7- or 12-entry Equation data.Reduced unnecessary rendering work for hidden Q.E.D. spirals.Improved the readability of right-side menu labels.

- Idle Spiral - Full Release - 27 August 2026
Idle Spiral — Full Release, and What Comes Next Thank you for waiting. It took longer than we said it would. Idle Spiral is now fully released, and it arrives together with the largest piece of content we have built so far: Hanoi. Maintenance continues Smaller updates keep coming, and the focus will be the UI. Long sessions deserve an interface that stays out of the way, and there is still work to do there. Expect steady, unglamorous improvements. What we are building next Season System! You could think of it as a fourth layer of prestig A Season runs on an entirely separate save. You beset of conditions that changes from one Season to the next, and your run is measured against everyon The point is not difficulty for its own sake. Players who have reached the deepest parts of this game have, in a real sense, finished it — and there is no way back to the feel. A Season gives that back, a…

- Fixed severe whole-game and Hanoi slowdowns affecting advanced saves. - Fixed excessive recurrence multiplier calculations that ignored the configured currency update interval. - Optimized Hanoi chain attacks without changing their timing, damage, or rewards. - Removed the background 5 FPS limit that could remain active after Alt+Tab, minimizing, or using the Steam Overlay. - Reduced repeated Steam ownership checks performed by the Design HUD. - Added a locked Q.E.D. teaser and Steam store link to the Design catalog. - Critical Chance above 100% now converts into Attack. - Super Critical Chance above 100% now converts into Super Critical Damage. - Fixed the Super Critical Battle reward effect not being applied correctly. - The Battle Auto Start preference now persists across restarts. - Improved Attack Speed reward descriptions to show effective multipliers and diminishing returns. -…

- Renewal of Spiral Design - 14 August 2026
Main SpiralThe default spiral has been experimentally migrated from the legacy rendering system to a new rendering method.Only the default spiral uses the new renderer in this update. Please report any visual glitches, performance issues, or other unexpected behavior.If you encounter a problem, you can switch back to the legacy renderer in Settings.This new rendering system will serve as the foundation for additional spiral designs planned for future updates Redesigned the Banach Equation as a long-term progression system. It starts at +0.001% Hanoi DPS, reaches ×3 at Lv. 10,000, and gradually approaches ×4.Significantly reduced Banach exp requirements and reworked how Equation Speed affects its progression.Existing Banach levels and partial progress are converted automatically to the new system.Improved compatibility with older PC saves and fixed an issue affecting some saves reset in…
- v3.0.11 - 12 August 2026
\ Removed the unintended legacy hard cap on Battle Attack Speed. The former cap value now remains only as the Scavenger Mode unlock threshold.Extremely large attack counts are now retained and processed in bounded batches instead of being discarded.Fixed Nuke and Scavenger calculations that could impose an artificial minimum Time to Attack based on the former cap.Improved consistency for batched damage, defeats, rewards, difficulty, Nuke credit, Loot, Milestones, Battle SpiralPoints, Combo, and Logarithm Challenge progress.Updated supported offline battles to use the same high-volume progression rules.Fixed extremely small Time to Attack values and other extreme numbers displaying as 0 or Infinity in some views.Fixed Battle Reward Multiplier and difficulty bonuses not applying to normal reward tiles in Another Spiral and FixPoint.Another Spiral's Convergence reward and FixPoint's Hanoi…

- v3.0.7 - 7 August 2026
- Fixed the main spiral not rendering at all on late-game saves. Its coordinates overflowed once your distance passed what a double can hold, so nothing was drawn while the game kept simulating normally.- Fixed "Infinity" being drawn across the middle of the screen. The X axis scale labels overflowed past 10^308.- Fixed the view starting wildly zoomed out. The spiral scale began each session at 1 and crept toward your actual distance, leaving the spiral outside the camera for the first several minutes.- Fixed spirals not appearing in Spiral Equation, in Z-Reactor, or for your own side in Battle. Their curves collapsed onto a single point whenever the panel was closed while they were still drawing.- Fixed the Z-Reactor 3D shapes being completely absent.- Fixed the Milestone panel being impossible to close. The close button was hidden underneath the menu bar, and leaving the screen with i…
