Equal Echoes

How Equal Echoes Works

Each round draws five independent uniform values from thirteen pockets, numbered 0 to 12. The raw score is calculated by summing the squared position-index differences for every unordered pair of equal readings. Values that do not match do not contribute. Repeated equal values create distinct position pairs.

  • Lower covers the first floor(number of distinct attainable scores / 2) scores.
  • Upper covers the remaining scores.
  • Even covers even integer scores.

Tickets can overlap. You must choose one ticket before spinning. One whole stake covers all independent readings in a multi-spin sequence.

Payout and Settlement

If your selected ticket matches the result, the gross payout is 0.96 × captured whole stake × total support / number of winning ordered outcomes. A miss returns zero. The settlement takes 480ms. During this time, and throughout any auto queue, your stake, ticket selection, and refill option remain locked. Sound remains available during active settlement.

Mathematical Evidence

Exact probabilities and gross RTP are recorded in math modes. Different tickets can overlap. Simulation measurements are supporting sample observations and not the mathematical payout law.

Controls and Auto Play

Auto play schedules at most ten draws. The Stop button cancels future draws, while active draws finish their settlement. There is no early bank. Controls for stake, mode, and refill are locked while active and through any auto queue.

Wallet and Persistence

The wallet persists locally. Fractional carry is preserved across settlement, refill, and reload. When fully idle and the balance is below 10, a manual refill sets the balance to exactly 1000, preserving fractional carry. Settled balance persists locally including zero. Reloading the page discards unfinished draws without refund or resume.

Identity and Privacy

This demo uses browser localStorage for settled balance and fractional carry. This does not establish anonymity or exclude other processing. The template declares a Google Fonts stylesheet. No account login or payment flow is implemented in this demo. The 18+ label reflects this guide's intended audience policy, not a universal legal age or implemented gate.

Frequently asked questions

How is the score calculated?

The raw score sums squared position-index differences over every unordered pair of equal readings. Different values do not contribute; repeated equal values create distinct position pairs.

What happens if I reload during a draw?

Reload discards unfinished draws without refund. Only settled balances persist locally.

How do I refill my virtual coins?

When fully idle and the balance is below 10, manual refill sets the balance to exactly 1000 with fractional carry preserved.
