Exact rules, probabilities, and payout structures are derived from the supplied contract and mathematical evidence, not from external marketing. Always verify the operator's status before playing.
Game Mechanics: Interval Relation
The core mechanic draws four independent uniform readings from thirteen pockets (0–12). These are split into two pairs:
- Interval A: The first two readings, sorted into a closed interval.
- Interval B: The last two readings, sorted into a closed interval.
Scoring follows a strict priority order:
- Equal (Score 4): Intervals are identical.
- Disjoint (Score 0): Strictly separate intervals.
- Containment (Score 2): One interval is inside the other without equality.
- Shared Endpoint (Score 1): Intervals share an endpoint but have zero-length intersection otherwise.
- Partial Overlap (Score 3): Otherwise.
A singleton interval inside another is classified as containment. Tickets (Lower, Upper, Even) are selected before spinning. One stake covers all four independent readings.
What Philippine Players Should Check
When playing the Semibola demo in the Philippines, you should verify key details directly with the operator. First, check if the brand supports Philippine Peso (PHP) for future real-money play, though the current demo uses virtual coins. Second, confirm if popular local payment methods like GCash and Maya are accepted for deposits and withdrawals, as this is crucial for convenience. Third, check if Semibola holds a valid license from PAGCOR, the national regulator, to ensure legal compliance. Finally, review the privacy policy to see how your data is handled.
- Verify if GCash or Maya are listed as supported deposit methods.
- Check for a visible PAGCOR license number on the site.
- Confirm if the virtual coin balance converts to real PHP.
Payouts and Settlement
For a selected ticket, the gross payout is:
- Miss: 0
- Win: 0.96 × captured whole stake × total support / number of winning ordered outcomes
Different tickets can overlap. The exact winning counts and support values are recorded in the math modes. Settlement takes 480ms. Stake, ticket, and refill options are locked during active settlement and any auto queue.
Mathematical Evidence
| Ticket | Exact Probability (Num/Den) | Exact Gross RTP | Measured RTP |
|---|---|---|---|
| 0 (Lower) | 10452 / 28561 | 0.96 | 96.24906161194029 |
| 1 (Upper) | 18109 / 28561 | 0.96 | 95.99069944005743 |
| 2 (Even) | 20553 / 28561 | 0.96 | 96.02645932447817 |
Measured RTP values are sample observations, not promised returns. The exact gross RTP for all tickets is 0.96.
Wallet and Persistence
The demo wallet starts with 1000 virtual coins. Fractional carry persists across settlement, refill, and reload. If the balance is below 10 and the user is idle, a manual refill sets the balance to exactly 1000, preserving fractional carry. Settled balances persist locally, including zero. Unfinished draws are discarded on reload without refund or resume. Controls are locked while active.
Identity and Privacy
The query identity is unverified. The demo uses localStorage for balance and fractional carry, but this does not prove anonymity or exclude other processing. A Google Fonts stylesheet is declared in the template, but actual request capture is pending. There is no account login or payment flow. The 18+ label is this guide's audience policy, not a legal age gate.
Control and Stopping
Auto mode schedules at most ten draws. The Stop button cancels future draws, but active draws finish. Sound remains available throughout. There is no early bank option. Stake, ticket, and refill remain locked through settlement and the auto queue.
Frequently asked questions
Is Semibola a licensed casino operator?
No. The identity is unverified. No primary source confirms Semibola as a licensed operator, registered business, or official app. This is an independent guide with a virtual-coin demo.
How is the score calculated?
Four readings (0–12) are split into two intervals. Scores are assigned by priority: Equal=4, Disjoint=0, Containment=2, Shared Endpoint=1, Partial Overlap=3. Tickets (Lower, Upper, Even) predict these scores.
What happens if I reload during a draw?
Unfinished draws are discarded without refund or resume. Only settled balances persist locally. Fractional carry is preserved across reloads.
Is Semibola licensed in the Philippines?
It is unverified. You should check the website's footer or 'About' section for a PAGCOR license number and verify it on the official PAGCOR registry.
Can I use GCash or Maya here?
The current demo uses virtual coins. Check the 'Cashier' or 'Payments' section to see if GCash or Maya are supported for real-money transactions.
