About the Semibola Browser Demo

The official website of semibola. This guide provides an independent look at the Semibola browser demo, focusing on its specific game mechanics, wallet behavior, and observed technical facts. The demo features the "Interval Relation" game, a unique logic-based system that differs from standard casino offerings. This page clarifies what is known from primary sources and what remains unverified, ensuring readers understand the scope of the demo without assuming external operator identity.

Understanding the Interval Relation Game

The core of the Semibola demo is the "Interval Relation" game. This is not a traditional slot or roulette but a logic-based draw system. The game involves drawing four independent readings, each uniformly distributed between 0 and 12. These readings are sorted into two pairs: the first two form Interval A, and the last two form Interval B.

The outcome is determined by the relationship between these two intervals. The system checks conditions in a specific order to assign a score:

  • Equal Intervals (Score 4): If Interval A and Interval B are identical.
  • Strict Disjointness (Score 0): If the intervals do not overlap at all.
  • Containment (Score 2): If one interval is fully contained within the other, but they are not equal.
  • Shared Endpoint (Score 1): If the intervals touch at exactly one point with no area overlap.
  • Partial Overlap (Score 3): If the intervals overlap in a way that does not fit the previous categories.

Players select a ticket before spinning: Lower (covers scores 0 and 1), Upper (covers scores 3 and 4), or Even (covers scores 0, 2, and 4). Note that score 0 is covered by both Lower and Even tickets, meaning tickets can overlap. The payout is calculated as 0.96 times the captured stake divided by the exact probability of the winning outcome.

Wallet Behavior and Settlement

The demo uses a local wallet stored in the browser's localStorage. The initial balance is set to 1000 virtual coins. Unlike many online games, there is no account creation or cash withdrawal process. The wallet behavior is defined by specific rules:

  • Fractional Carry: Any fractional balance persists across settlements, refills, and reloads.
  • Manual Refill: When the balance falls below 10 and the user is fully idle, a manual refill sets the balance to 1000. This restoration does not automatically add to the existing balance; it resets it.
  • Reload Behavior: Reloading the page discards any unfinished draws without refund or resuming progress. However, settled balances are saved locally.
  • Locking Mechanism: Stake, ticket selection, and refill controls are locked while the game is active and throughout any auto-queue settlement. Only sound controls remain available.

Mathematical Evidence and RTP

The expected Return to Player (RTP) is a mathematical expectation, not a guarantee for any single session. The demo uses an exact gross RTP of 0.96 (96%). This is derived from the formula: Gross Return = 0.96 × Captured Stake × Total Support / Number of Winning Outcomes.

Simulation data from one million rounds provides the following observed results:

Ticket TypeExact Probability (Numerator/Denominator)Measured RTP
Lower (Ticket 0)10,452 / 28,56196.25%
Upper (Ticket 1)18,109 / 28,56195.99%
Even (Ticket 2)20,553 / 28,56196.03%

These measured RTPs are sample observations and may vary slightly due to simulation variance. The exact probabilities are recorded in the game's math modes.

Controls and Game Modes

The demo offers specific controls to manage the game flow:

  • Auto Mode: Schedules at most ten draws automatically. The user can stop future draws at any time, but the current captured outcome will finish settling.
  • Stop Function: Cancels future draws in the queue. The active draw continues until its 480ms settlement period ends.
  • No Early Bank: There is no mechanism to bank winnings early; the auto queue runs its course unless manually stopped.
  • Sound: Audio feedback remains available even when other controls are locked during settlement.

Observed Site Facts and Identity

This guide is independent and does not claim an official operator identity for Semibola unless supported by reviewed primary-source facts. The following facts are observed from the demo environment:

  • Identity Status: Unverified. The brand name "Semibola" does not automatically imply a specific licensed operator, company history, or jurisdiction.
  • Storage: The demo uses browser localStorage for balance and fractional carry. This does not prove anonymity or exclude other server-side processing.
  • Third-Party Requests: The template declares a Google Fonts stylesheet. Actual browser request capture is pending, so no complete inventory of third-party requests is claimed.
  • Account and Payment: There is no demo account flow or payment cashier. Virtual coins have no cash value.

Audience and Responsible Use

The intended audience for this guide is 18+, which is a policy for this demo's context and not necessarily a universal legal age gate or a claim about local laws. The game caps and resets are mechanical features, not guarantees of safe behavior. Players are encouraged to use voluntary breaks and self-monitored time limits. If you require local qualified help, you may seek it independently, as this guide does not provide specific hotline contacts or clinical diagnoses.

Frequently asked questions

Is Semibola a licensed casino operator?

This guide does not verify that Semibola is a licensed casino operator. The brand name is used for this browser demo, but no official address, license, or corporate history is confirmed by reviewed primary-source facts. The demo uses virtual coins with no cash value and no cashier system.

What happens to my balance if I reload the page?

Reloading the page discards any unfinished draws without a refund or resuming progress. However, your settled balance is saved locally in the browser's localStorage. If your balance falls below 10 and you are idle, you can manually refill it to 1000.

How is the score calculated in Interval Relation?

Four numbers are drawn (0-12). The first two form Interval A, and the last two form Interval B. Scores are assigned based on the relationship: Equal (4), Disjoint (0), Containment (2), Shared Endpoint (1), or Partial Overlap (3). The order of checks matters; for example, a singleton inside another interval is classified as containment.
