Independent guide
This independent RK 89 guide supplies its own free Binary Crossing Roulette demo. Operator identity, domains, licence, apps, payments, support and commercial game equivalence have not been independently verified. No operator account or commercial link is supplied here.
Two draws and binary XOR
One paid round draws two independent uniform pockets0–12. Score is their bitwise XOR. Each binary position is1 only when the two input bits differ. For example,5 XOR3 is6. All169 ordered pairs are equally likely; attainable scores are0–15.
Three actual score bands
Choose lower scores0–5,middle6–10 orupper11–15 before staking. These bands have69,50 and50 ordered pairs respectively. Both draws use one stake and settle together, with no mid-round cash-out.
Exact probability and total return
Hit probabilities are69/169,50/169 and50/169. Total return on a hit is stake×0.96×169 divided by winning pairs:2.351304348 times stake for lower,3.2448 for middle orupper. A miss returns zero; total return includes stake.
Wallet and restoring balance
Settled balance and fractional payout carry persist in localStorage. Reloading during a round ends it without refunding its deducted stake. Outside a round, refill sets 1000 coins when balance is below the smallest stake; it does not add 1000 or erase fractional carry. Band and stake return to defaults on reload.
Frequently asked questions

What is binary XOR?
One paid round draws two independent uniform pockets0–12. Score is their bitwise XOR. Each binary position is1 only when the two input bits differ. For example,5 XOR3 is6. All169 ordered pairs are equally likely; attainable scores are0–15.
Which score bands can I choose?
Choose lower scores0–5,middle6–10 orupper11–15 before staking. These bands have69,50 and50 ordered pairs respectively. Both draws use one stake and settle together, with no mid-round cash-out.
What does a hit return?
Hit probabilities are69/169,50/169 and50/169. Total return on a hit is stake×0.96×169 divided by winning pairs:2.351304348 times stake for lower,3.2448 for middle orupper. A miss returns zero; total return includes stake.
Does96% guarantee my session?
Exact expected return is 96% in every band: hit probability multiplied by the total-return multiplier is 0.96. Bands change hit frequency and variance, not expectation. A 96% expectation is not a promise of a single spin or a short session. This demo does not certify an external operator or reproduce its games.
What survives reload?
Settled balance and fractional payout carry persist in localStorage. Reloading during a round ends it without refunding its deducted stake. Outside a round, refill sets 1000 coins when balance is below the smallest stake; it does not add 1000 or erase fractional carry. Band and stake return to defaults on reload.
Can coins be withdrawn?
Demo coins cannot be exchanged or withdrawn and are unrelated to an operator account. Only this browser’s settled wallet and fractional carry persist. Clearing cache alone may leave localStorage intact; clearing site data removes local progress.
What data can be exposed?
There are no account, payment or identity-document forms here. Fonts, the visit counter, server and CDN requests can expose technical data including IP and browser details. Complete anonymity, third-party data use and cookie lifetimes are not established. Clearing cache alone may leave localStorage intact.
Are external claims verified?
A matching brand, professional design, search result or HTTPS connection does not verify ownership, authorisation or safety. Match any claim against an independent regulator register, including entity, current status, scope and listed domains. No operator licence or service is endorsed here.
How can I limit play?
This demo is restricted to adults 18+ and uses coins without cash value or prizes. Set session time and virtual-coin limits before playing, then stop at those limits. Raising a stake to recover losses does not improve expectation. If playing affects responsibilities or becomes hard to control, stop and seek suitable independently verified local support.
