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.

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.
