No cashier or redeemable balance
This demo has no real-money deposit, withdrawal, cashier or exchange of coins for currency. A virtual balance is a local game value rather than a bank balance or a redeemable claim. Restoring it is a game control, not a payment transfer. The guide does not establish payment methods, fees, verification requirements, limits or processing times for an outside Sun20 service.
Two symbols make one integer
Each of two independent reels selects one of sixteen equally likely hexadecimal symbols: 0 through 9, then A through F. The letters have values 10 through 15. Calculate n = 16 × first value + second value + 1, giving each integer from 1 to 256 equal probability. Symbols 0 and B give 12; F and F give 256. Both reels share one stake. There are no separate row bets, matching-symbol prizes or bonus rounds.
Use every positive divisor
List all positive divisors of n, including 1 and n itself, and let k be the number of divisors. Calculate k × the sum of their squares − the square of their sum. The minimum across the 256 starting integers is 0, so the reward score equals this statistic. It also equals the sum of squared differences over all unordered pairs of divisors. The game does not divide by k or k²: its score is not a normalized statistical variance. No proper-divisor chain or repeated replacement is involved.
Gross return and fractional carry
The gross multiplier is 0.96 × selected weight ÷ that curve’s exact mean weight. The sums across all 256 integers are 29,753,529 for Linear, 11,204,376,612,271 for Square and 7,113,856,702,189,995,795 for Cube. Divide each sum by 256 to get its mean. Multiply the captured stake by the multiplier for the raw gross return. Add stored fractional carry, credit the whole-number part and save the remaining fraction. Net whole-coin change is the credit minus the stake already deducted. Carry is added before rounding down, and zero raw return leaves existing carry unchanged.
Local wallet and manual restoration
A fresh wallet starts with 1,000 virtual coins. The balance, including zero, and fractional carry are saved in browser localStorage. When no round is active and the balance is below 10, Restore balance sets it to exactly 1,000. It does not add 1,000 or run automatically. Restoration preserves carry, the selected stake and the selected curve. It is available whenever those conditions are met. Coins have no cash value and cannot be withdrawn.
Reloading an unfinished spin
Reloading during a spin leaves the captured stake deducted. The unfinished round ends without refund, payout, continuation or resume. The remaining saved balance and existing carry remain local. Controls return to stake 20 and Linear, and a new spin still needs enough balance for its chosen stake. Ordinary settlement and balance restoration do not reset those settings. Reloading is not a way to recover the stake or complete a round.
Frequently asked questions
Can I withdraw the virtual coins?
No. They have no cash value and this demo provides no deposit, withdrawal or exchange service.
Does restoration clear carry or reset settings?
No. While idle with a balance below 10, the manual control sets the balance to exactly 1,000 and preserves carry, stake and reward curve.
What happens if I reload during a spin?
The captured stake remains deducted and the unfinished round receives no refund or payout and cannot resume. Saved remaining balance and carry stay local; controls reset to stake 20 and Linear.
