An independent guide
This guide discusses the name HH666 and provides its own original browser demonstration, Square Root Divisor Roulette. The demonstration does not establish an affiliation with an outside business or reproduce an outside product.
Two readings and the score
Draw two independent uniform integers from 0 through 12. Multiply (first + 1) by (second + 1), find the largest perfect-square divisor of the product and take its square root as the score. There are 169 equally likely ordered pairs; the scores themselves are not equally likely.
Bands and gross multipliers
Lower accepts scores 1, 2, 3, 4 and covers 148 of 169 pairs. Middle accepts 5, 6, 7, 8 and covers 16 pairs. Upper accepts 9, 10, 11, 12, 13 and covers 5 pairs. A hit returns stake × (0.96 × 169 / coverage); a miss returns zero. The multipliers are approximately 1.096216, 10.140000 and 32.448000. The interface rounds multipliers to six decimal places and hit percentages to three; settlement uses the unrounded multiplier. Gross return includes the stake, so it is not net profit.
Choose before drawing
Choose a stake of 10, 20, 50 or 100 and one score band before starting. Starting deducts and saves exactly one stake; both readings belong to that captured stake and selected band. During the round, stake buttons, band buttons, the draw button and restoration are disabled. Sound remains available. After settlement, the chosen stake and band remain until changed or the page is reloaded.
Whole coins and fractional remainder
At settlement, stake × unrounded multiplier is added to the previously saved fractional remainder. The whole-number part is credited to the wallet, and the new fraction is stored separately for later rounds. The displayed wallet holds whole coins. A zero-return round preserves the previous remainder. The remainder persists through settlement, manual restoration and reload. Net wallet change is credited coins minus the stake deducted.
Reload and defaults
Reloading or leaving an unfinished round gives no refund, payout or resume. Its saved stake deduction remains. The saved wallet, including zero, and the previously saved fractional remainder remain while browser storage retains them. Reload resets the selected stake to 20 and band to Lower. It does not restore the wallet to 1,000 or continue the previous round in the background.
Frequently asked questions
How is the score calculated?
Multiply the two readings after adding 1 to each. Take the square root of the largest perfect-square divisor of that product. Readings 2 and 3 produce 12, largest square divisor 4 and score 2.
Can I collect after the first reading?
No. There is no intermediate collection. Both readings belong to the same stake and band; settlement occurs after the second reveal.
What is locked during a round?
Stake, band selection, restoration and the draw button are disabled. Sound remains available. The captured stake and band cannot be changed.
