Concordance Pair: Rules, Math, and Demo

The game draws 6 independent uniform values from 0 to 12. The first three values are X coordinates and the last three are Y coordinates of three labelled points. The raw score counts unordered point pairs where both coordinate differences have the same nonzero sign. Tied coordinates contribute zero.

Tickets can overlap. You must choose one ticket before spinning: Lower, Upper, or Even. A matching result returns a gross payout based on the exact probability of that outcome. A miss returns zero.

Lower covers raw scores 0 and 1; Upper covers 2 and 3; Even covers 0 and 2. Only the selected ticket is paid, even when ticket conditions overlap.

All independent draws are uniform thirteen-pocket values (0..12). The exact winning counts and support are recorded in math modes. Different tickets can overlap. The exact gross RTP is 0.96 for all modes.

Simulation measurements are supporting sample observations, not the mathematical payout law or a promised return.

Normal-motion settlement takes 480 ms from the first animation frame; reduced motion settles on the first frame.

One whole stake covers all six readings. Choose Lower (0–1), Upper (2–3) or Even-score (0 and 2) before spinning. Approximate gross multipliers are displayed. Stake, ticket and refill remain locked during the active draw and auto queue; sound remains available.

Auto schedules at most ten draws. Stop cancels future draws and active draws finish. One whole stake covers all independent readings. Stake, ticket and refill stay locked through settlement and queue.

The initial balance is 1000. When fully idle and balance below 10, manual refill sets 1000 with fractional carry preserved. Reload discards unfinished draws without refund. Settled balance persists locally including zero. Busy controls: Stake, mode and refill are locked while active and through any auto queue; sound remains available. Fractional carry persists across settlement, refill and reload.
