Personal Session Boundaries
Choose a personal time or virtual-coin boundary before starting and stop when it is reached. A restored balance is optional and does not make further rounds necessary. The demo does not enforce a timer, diagnose behaviour or provide account exclusion. Taking a break does not change future hidden layouts or raise the expected return.
Expected Return and Different Hit Rates
Each ticket has exact unrounded expected RTP of 96%: its hit probability multiplied by its gross return multiplier is 0.96. This is an expectation across captured stakes, not a promised result for a session or a win frequency. The bands have different hit probabilities. Following past readings, changing stakes or switching tickets between rounds does not raise the expected return.
The Original Demo’s Scope
These pages describe this guide’s scope and its original demo. They do not rank an external business, confirm financial reliability, provide a legal opinion or establish permission to gamble in any country. External activities have rules and eligibility requirements that this guide has not verified. The original demo does not reproduce an external product’s interface or odds.
Appropriate Local Support
If play is becoming difficult to stop or affecting daily responsibilities, close the demo and consider qualified local support. No 9JJ help line, account-blocking feature or treatment service is verified by this guide. Its pages do not diagnose a condition, give treatment instructions or substitute for an appropriate professional service.
Virtual Wallet and Restoration
A new local wallet starts with 1000 virtual coins. Stakes are 10, 20, 50 or 100, initially 20. One round deducts one captured stake. Settings and restoration lock during the two reveals. While idle below 10 coins, restoration sets the wallet to exactly 1000, rather than adding 1000. Saved fractional payout carry remains. The counters have no cash value, prize or withdrawal route.
Four-Bit Hamming Distance
Bit Gap Roulette draws two independent uniform pocket readings from 0 through 12, giving 169 equally likely ordered pairs. Express each reading with four binary bits. The score is the Hamming distance: the number of positions whose bits differ. For readings 0 (0000) and 1 (0001), the score is 1. For readings 3 (0011) and 12 (1100), all four bits differ and the score is 4. The rule belongs only to this original demo.
Frequently asked questions
Is this an official operator site?
9JJ is a search label, not an operator identity established by this guide. 9jj.info is an independent information guide with its own Bit Gap Roulette demo. No company, licence, official account domain, commercial game catalogue, payment service, app publisher or support contact is verified here. Search position, a similar name and page appearance cannot establish those facts.
How is the score calculated?
Bit Gap Roulette draws two independent uniform pocket readings from 0 through 12, giving 169 equally likely ordered pairs. Express each reading with four binary bits. The score is the Hamming distance: the number of positions whose bits differ. For readings 0 (0000) and 1 (0001), the score is 1. For readings 3 (0011) and 12 (1100), all four bits differ and the score is 4. The rule belongs only to this original demo.
Which scores does each ticket contain?
Before starting, choose one of three score-band tickets. Band one contains score 0 and occurs in 13 of 169 pairs. Band two contains scores 1 and 2 and occurs in 106 pairs. Band three contains scores 3 and 4 and occurs in 50 pairs. These are bands of attainable scores, not equal-probability bets. Exactly one band contains the final score.
When is a round paid?
Starting deducts one captured stake and locks the ticket, stake settings and restoration. The first reading is incomplete and pays nothing. After the second reading, a matching ticket returns the captured stake multiplied by 0.96 divided by its exact hit probability, including the stake in that gross credit. A miss returns zero. There is no intermediate collection or extra charge. The exact gross multipliers are 162.24/13, 162.24/106 and 162.24/50, approximately 12.480000×, 1.530566× and 3.244800×.
Does 96% promise a session result?
Each ticket has exact unrounded expected RTP of 96%: its hit probability multiplied by its gross return multiplier is 0.96. This is an expectation across captured stakes, not a promised result for a session or a win frequency. The bands have different hit probabilities. Following past readings, changing stakes or switching tickets between rounds does not raise the expected return.
How does restoration work?
A new local wallet starts with 1000 virtual coins. Stakes are 10, 20, 50 or 100, initially 20. One round deducts one captured stake. Settings and restoration lock during the two reveals. While idle below 10 coins, restoration sets the wallet to exactly 1000, rather than adding 1000. Saved fractional payout carry remains. The counters have no cash value, prize or withdrawal route.
