Add-on Idle Spiral

Idle Spiral - Q.E.D. Pack

  • Steam
  • PC

Description

Add the Q.E.D. Spiral Design to Idle Spiral: a bright mathematical theme where proofs scatter from a living spiral. Equip it for 1.5× normal Hanoi DPS, then advance game time to train lasting exponent bonuses for a–f and k, even when the Design is no longer active.

A proof completed over time.

Idle Spiral - Q.E.D. Pack adds Q.E.D., a new Spiral Design for Idle Spiral. Across a bright sheet of graph paper, a vermilion spiral stretches outward as blue, ink-black, and red fragments of mathematics break apart and gather into proofs. The interface also shifts into Q.E.D.'s dedicated light visual style.

Active Effect

While Q.E.D. is assigned to an active Design slot, it multiplies normal Hanoi DPS by 1.5×.

Passive Effect

Owning this DLC applies exponent bonuses to a, b, c, d, e, f, and k even when Q.E.D. is not equipped. Each exponent begins at +0.010. Keep Q.E.D. active and advance game time to train them in sequence: a→b→c→d→e→f→k. Each exponent can reach +0.100, and completing every proof requires a total of 360 game days.

Proof Progression

Time Warp advances the proof while Q.E.D. is active, and neither Prestige nor Tornado Prestige resets its progress. Removing Q.E.D. pauses training, but every exponent bonus already earned remains active as a passive effect.

Watch formulas scatter from the spiral and slowly return as a completed proof. The longer you play, the closer Q.E.D. comes to completion.
