While the demo runs on virtual currency, real-money play may involve PHP. Always check if Semibola supports GCash or Maya and confirm their regulatory status with PAGCOR before playing.
How Interval Relation Works
The game involves drawing 4 independent uniform readings from a set of thirteen pockets (values 0–12). To determine the score, the first two readings are sorted into a closed interval A, and the last two readings are sorted into a closed interval B. The classification follows a strict order:
- Equal Intervals (Score 4): If intervals A and B are identical.
- Strict Disjointness (Score 0): If the intervals do not touch or overlap.
- Containment without Equality (Score 2): If one interval is inside the other but they are not equal.
- Shared Endpoint (Score 1): If the intervals share a single point (zero-length intersection).
- Partial Positive Overlap (Score 3): If they overlap but do not meet the above criteria.
For example, if the drawn symbols are [0, 0, 0, 0], the intervals are [0,0] and [0,0], resulting in a score of 4. If the symbols are [0, 1, 2, 3], the intervals are [0,1] and [2,3], which are disjoint, resulting in a score of 0.
What Philippines Players Should Check
Before engaging with Semibola, readers in the Philippines should verify key operational details. First, confirm if the platform supports the Philippine Peso (PHP) for real-money games, as the demo uses virtual coins. Second, check if popular local payment methods like GCash and Maya are available for deposits and withdrawals. You can find this by looking for the cashier or banking section on Semibola’s official site.
Regulatory safety is crucial. Check if Semibola holds a valid license from the Philippine Amusement and Gaming Corporation (PAGCOR) or another recognized authority. Look for a license number in the website footer and verify it on the regulator’s official portal. Additionally, ensure you are of legal age (18+) and practice responsible gambling.
- Verify PHP currency support in the account settings.
- Check for GCash and Maya integration in the deposit menu.
- Confirm PAGCOR licensing via the official regulator website.
Payout and Settlement
When a ticket matches the result, the gross payout is calculated as:
0.96 × Captured Whole Stake × Total Support / Number of Winning Ordered Outcomes
A miss returns zero. The game processes a 480ms settlement period. During this time, and while an auto-queue is active, your stake, selected ticket, and refill options are locked. The actual gross RTP for all modes is exactly 0.96, though measured simulation results may vary slightly (e.g., ~96.24% for ticket 0).
Tickets and Modes
You must preselect one ticket before spinning. Tickets can overlap, meaning one outcome might satisfy multiple tickets, but you choose only one to play.
| Ticket | Description |
|---|---|
| 0 (Lower) | Covers the first floor(number of distinct attainable scores / 2) scores. |
| 1 (Upper) | Covers the remaining higher scores. |
| 2 (Even) | Covers even integer scores. |
The exact cutoff and approximate gross multiplier for each ticket are displayed in the demo interface.
Controls and Auto Play
The demo offers Auto and Stop controls:
- Auto: Schedules at most ten draws. Each draw is a whole outcome.
- Stop: Cancels future draws. Any currently active draw will finish its settlement process.
Sound remains available even when controls are locked during settlement.
Wallet and Persistence
The demo uses a local wallet with specific rules:
- Initial Balance: 1000 virtual coins.
- Refill: When fully idle and the balance is below 10, a manual refill sets the balance to exactly 1000, preserving any fractional carry.
- Persistence: Settled balances persist locally, even if the balance is zero. However, reloading the page discards any unfinished draw without a refund or resume option.
Mathematical Evidence
The following table shows the exact mathematical evidence from the owner contract for each ticket mode, based on 1,000,000 rounds:
| Ticket | Exact Probability (Num/Den) | Exact Gross RTP | Measured RTP |
|---|---|---|---|
| 0 (Lower) | 10,452 / 28,561 | 0.96 | ~96.25% |
| 1 (Upper) | 18,109 / 28,561 | 0.96 | ~95.99% |
| 2 (Even) | 20,553 / 28,561 | 0.96 | ~96.03% |
Note: Measured RTP is a sample observation and not the exact promised return.
Frequently asked questions
Does the demo require an account or login?
No. This is a browser-based demo with no account flow. Your balance is stored locally in the browser and does not require a registered user account.
What happens if I reload the page during a game?
If you reload the page, any unfinished draws are discarded without a refund. Only settled balances are preserved locally.
How is the score calculated?
Four readings (0-12) are drawn. The first two form interval A, and the last two form interval B. Scores are assigned based on the relationship between A and B: 4 for equal, 0 for disjoint, 2 for containment, 1 for shared endpoint, and 3 for partial overlap.
Is Semibola licensed in the Philippines?
This demo site does not verify Semibola’s license. Check the official Semibola website for a PAGCOR license number and verify it on the PAGCOR portal to ensure it is valid for Philippine players.
Does Semibola accept GCash or Maya?
This guide does not confirm payment methods. Visit Semibola’s official cashier section to check if GCash, Maya, or other local Philippine payment options are currently supported for deposits.
