Game Mechanics and Scoring
The core mechanic involves four independent uniform readings from the range 0–12. The first two readings form closed interval A, and the last two readings form closed interval B. The raw score is determined by the containment relationship between A and B:
- Score 2: Returned if the intervals are equal (e.g., [0,0] and [0,0]).
- Score 1: Returned if one interval is a proper subset of the other.
- Score 0: Returned if neither interval contains the other.
Singleton intervals (where both readings in an interval are identical) remain valid and can score based on containment. Tickets can overlap, meaning a single outcome can satisfy multiple ticket conditions, but only one ticket is selected per spin.
Ticket Modes and Payouts
Before spinning, you must choose one of three ticket modes. The gross payout is calculated as 0.96 × captured whole stake × total support / number of winning ordered outcomes for a matching result. A miss returns zero.
| Ticket | Description |
|---|---|
| Lower | Covers the first floor(number of distinct attainable scores / 2) scores. |
| Upper | Covers the remaining scores. |
| Even | Covers even integer scores. |
The exact cutoff for Lower and Upper depends on the distribution of attainable scores. Different tickets can overlap in their winning conditions.
Mathematical Evidence and RTP
The following table shows the exact mathematical probabilities and measured returns for each ticket mode based on simulation data. Note that measured RTP is a sample observation and not a guaranteed session result.
| Ticket | Exact Probability | Exact Gross RTP | Measured RTP |
|---|---|---|---|
| Lower | 16,172 / 28,561 | 0.96 | 96.03% |
| Upper | 12,389 / 28,561 | 0.96 | 95.90% |
| Even | 16,497 / 28,561 | 0.96 | 96.05% |
Controls and Settlement
Controls: You preselect your ticket (Lower, Upper, or Even) before spinning. A whole stake covers the complete multi-spin outcome. Settlement takes 480ms.
Locking: During active settlement and any auto queue, the stake, ticket selection, and refill button remain locked. Sound remains available throughout. Auto mode schedules at most ten draws. The Stop button cancels future draws, but active draws finish settling. There is no early bank.
Wallet and Persistence
Initial Balance: The demo starts with a balance of 1000 virtual coins.
Refill: When the wallet is fully idle and the balance is below 10, a manual refill sets the balance to exactly 1000. Fractional carry is preserved during this process.
Persistence: Settled balances persist locally, including zero balances. Fractional carry persists across settlement, refill, and reload. However, reloading the page discards any unfinished draws without refund or resume.
Examples and Identity
Worked Examples:
- Readings [0, 0, 0, 0]: Interval A=[0,0], Interval B=[0,0]. Equal intervals score 2.
- Readings [12, 12, 12, 12]: Interval A=[12,12], Interval B=[12,12]. Equal intervals score 2.
- Readings [0, 1, 2, 3]: Interval A=[0,1], Interval B=[2,3]. No containment, score 0.

Frequently asked questions
Does reloading the page refund unfinished draws?
No. Reloading the page discards unfinished draws without refund or resume. Only settled balances persist locally.
How is the refill amount determined?
When the wallet is fully idle and the balance is below 10, a manual refill sets the balance to exactly 1000 virtual coins, preserving any fractional carry.
Are the measured RTP values guaranteed?
No. The measured RTP values (e.g., 96.03%) are supporting sample observations from simulation. The exact Gross RTP is 0.96 for all tickets, but actual session results may vary.
