Rock paper scissors, strategy-proof
Real rock-paper-scissors isn't actually random — humans follow patterns (players favor rock, repeat winners, and switch after losses), and skilled opponents exploit them. The rock paper scissors wheel removes the psychology: a cryptographically random throw every time. Play against the wheel, or both players spin and the classic rules decide.
Ways to use it
Solo decisions: assign rock/paper/scissors to three options and spin — a three-way coin flip. Fair tournaments: both sides spin; no reads, no mind games, pure luck. Teaching probability: spin in count-wins mode and watch the three throws even out over 30 spins — a live statistics lesson. For a straight two-way call, the heads or tails wheel is one door over.
