WHY THIS GAME

Four values. One missing link.

Parity Rush turns the textbook identity C + PV(K) = P + S into a timed arithmetic loop. Every generated equation is internally balanced, one value is hidden, and a correct answer immediately deals the next card.

THE LOOP

Learn it in one round.

  1. 01

    Select Start 45-second run to receive a balanced equation with one hidden value.

  2. 02

    Read C as call value, PV(K) as the present value of the strike, P as put value, and S as spot value.

  3. 03

    Rearrange C + PV(K) = P + S to calculate the hidden value.
