Two readings and prime-factor load
Each reading independently chooses a uniform integer from 0 to 12. For readings a and b, calculate n = a × b + 1. Factor n into primes and sum each prime times its exponent; equivalently, sum prime factors counting all repetitions. The integer 1 has score 0. For example [1, 11] gives n = 12 = 2² × 3, with score 2 × 2 + 3 × 1 = 7, not 5 or 3. There are 169 equally likely ordered pairs; n is not uniformly distributed.
Tickets, accepted scores and gross returns
Choose a ticket before starting. Lower accepts 0, 2, 3, 4, 5, 6, 7, 8, 10, 11, 12, 13 and 14: 97/169 pairs. Middle accepts 15, 16, 17, 18, 19, 20, 22, 23, 25, 26, 29, 31 and 34: 38/169. Upper accepts 37, 40, 41, 43, 61, 63, 67, 71, 73, 89, 97, 101 and 109: 34/169. These are discrete lists, not continuous intervals. On a hit, gross multiplier = (0.96 × 169) / ticket coverage: Lower 4056/2425 ≈ 1.672577; Middle 2028/475 ≈ 4.269474; Upper 2028/425 ≈ 4.771765. Raw gross return is stake times that multiplier; a miss returns zero. Hit probability times gross multiplier equals 24/25, or 96% expected gross RTP, for all three tickets. RTP is neither win probability nor a session guarantee.
Whole credited coins and fractional carry
At settlement, add raw gross return to saved carry, credit the whole part to the wallet and save the remainder. The result message and credited-coins summary show whole coins actually credited; the ticket’s gross multiplier is not net profit. A ticket miss has zero raw return and leaves old carry unchanged. Carry persists in localStorage across settlement, restoration and reload.
Balance and manual restoration
With no saved balance, the demo starts at 1,000 virtual coins. The recorded balance persists in localStorage, including zero. Only while idle and below 10 coins can you manually restore the balance to exactly 1,000. This sets the balance rather than adding 1,000, and keeps saved carry. Virtual coins have no cash value and cannot be withdrawn.
Reloading before settlement
If you reload before both readings appear and settlement is recorded, the already deducted stake remains deducted. The round ends without a refund, payout or continuation. Reload resets stake to 20 and ticket to Lower; saved balance and carry persist. Normal settlement retains the selected stake and ticket. To take a break, wait for settlement and do not start another draw.

Frequently asked questions
How is the score calculated?
Calculate n = a × b + 1 and sum its prime factors with all repetitions. The integer 1 has score 0. For example [1, 11] gives 12 = 2² × 3 and score 7.
Why do credited coins differ from gross return?
The wallet credits the whole part of raw return plus old carry and saves the remainder. For example 33.451546 with no old carry credits 33 and saves about 0.451546.
When can I restore the balance?
Only while idle and below 10 coins. Restoration sets the balance to exactly 1,000, retaining carry; it is not a real-money deposit.
