The queried name 12q and domain play12q.com are not evidence of an official company, account address, registered licence, or verified app. This guide does not infer a business entity, affiliation, or payment service from the query alone. No operator catalogue, support channel, KYC process, or cash withdrawal is established by this page.
The game mechanics, probabilities, and wallet behaviour described here are derived solely from the supplied source-bound owner contract and mathematical evidence for the Nested Intervals demo. Simulation measurements are supporting sample observations, not the mathematical payout law.
Game Mechanics: Nested Intervals
The Nested Intervals demo draws 4 independent uniform readings from a 13-pocket range (0–12). The first two readings form closed interval A; the last two form closed interval B.
Scoring
Raw score counts true containments:
- Equal intervals score 2.
- Proper containment scores 1.
- Neither scores 0.
- Singleton intervals remain valid.
Tickets and Payout
Choose one ticket before spinning:
- Lower: Covers the first floor(number of distinct attainable scores / 2) scores.
- Upper: Covers the rest.
- Even: Covers even integer scores.
Tickets can overlap. A matching result returns 0.96 × captured stake × total support / number of winning ordered outcomes. A miss returns 0. One whole stake covers all independent readings.
Controls and Settlement
- Auto schedules at most ten draws.
- Stop cancels future draws; active draws finish.
- Settlement takes 480ms.
- Stake, ticket, and refill stay locked through settlement and queue.
Wallet and Persistence
The demo uses a virtual wallet with specific persistence rules:
- Initial Balance: 1000 virtual coins.
- Refill: Manual only. When fully idle and balance is below 10, refill sets balance to exactly 1000, preserving fractional carry.
- Fractional Carry: Persists across settlement, refill, and reload.
- Settled Balance: Persists locally, including zero.
- Reload: Discards unfinished draws without refund or resume.
- Busy Controls: Stake, mode, and refill are locked while active and through any auto queue.
This is not an account-based system. There is no login flow, cash withdrawal, or network-synchronised account.
Mathematical Evidence and Simulation
The exact gross RTP for all tickets is 0.96. Below are simulation results from 1,000,000 rounds, supporting but not defining the payout law.
| Ticket | Winning Draws | Exact Probability | Measured RTP |
|---|---|---|---|
| 0 (Lower) | 566,403 | 16,172 / 28,561 | 96.03% |
| 1 (Upper) | 433,300 | 12,389 / 28,561 | 95.90% |
| 2 (Even) | 577,926 | 16,497 / 28,561 | 96.05% |
Expected RTP is not a promised session result. Different modes have different distributions.
Worked Examples
These examples use the actual game.js pure score function:
- [0, 0, 0, 0]: Raw Score 2 (Equal intervals).
- [12, 12, 12, 12]: Raw Score 2 (Equal intervals).
- [0, 1, 2, 3]: Raw Score 0 (No containment).
Privacy and Storage
Source uses browser localStorage for settled demo balance and fractional carry. This does not establish anonymity or exclude other processing. The template declares a Google Fonts stylesheet; actual browser request capture is pending. Clearing cached files may leave local storage. The absence of account controls does not prove no personal data are processed.
Audience and Responsibility
18+ is this guide's own intended audience policy, not a claim about local law or an implemented age gate. Responsible-use pages can describe optional pauses, a personal time/virtual-coin limit, and finding appropriate local qualified help. Do not assume the demo clinically trains behaviour or makes losses safe. No account-level blocking or self-exclusion tools are implied.
Frequently asked questions
Is 12q an official casino operator?
This guide does not verify an outside operator. It is an independent information guide. The queried name and domain are not evidence of an official company, account, app, or service. This demo belongs to this guide and does not certify any outside product.
How does the wallet refill work?
Refill is manual only. When the demo is fully idle and the balance is below 10, clicking refill sets the balance to exactly 1000, preserving any fractional carry. There is no automatic replenishment.
What happens if I reload during a draw?
Reload discards unfinished draws without refund or resume. Only settled balances persist locally.
