Binary Sprint

Race as eight famous scientists in a mobile binary puzzle sprint. Easy: four slots, targets 0–15. Hard: six slots in one row, targets 0–63. A symbolic die shows π, e, α, β, φ and ∞; its face is independent of the target. Tap slots to cycle 1, 0 and empty. Only leading zeros may be omitted; fill every slot from the first digit to the right edge. For zero, place 0 in the rightmost slot. Press Sprint to advance. Mistakes pause Sprint for two seconds while slots stay editable. Reach ten checkpoints before your solo rival or one online friend. The host sets difficulty; online races share seeded targets. Online requires creator Pro access.
