KKFF: Query and simulator

KKFF is a search topic in this independent guide. A name or domain resemblance establishes no business, official app, licence, financial offering or support channel. None is verified here. Border Length Ledger is our own virtual-coin simulator with its own exact rules; it is not an outside operator product or commercial replica.

Eight independent fair choices of0 or1 form one word. For each length1 through7, the software compares the prefix and suffix of that SAME length. A matching pair contributes that length to the raw score. The full length-eight word is excluded. Prefix and suffix may overlap. No player answer, letter rearrangement or separate row stake affects the calculation.

00000000 and11111111 match every proper length, so score1+2+3+4+5+6+7=28. The alternating word01010101 matches lengths2,4 and6, scoring12. Word00000001 has no proper border and scores0. These are automatic calculations on the drawn word, not bonus decisions or optional claims.

Raw scores0,1,2,3,4,5,6,7,8,12,28 occur74,82,26,38,14,6,6,4,2,2,2 times respectively. These counts total256. There are182 positive-score words. Weighting does not change which words score positive or zero. Positive gross credit may still be below the stake and is not necessarily profit.

The score is the sum of qualifying lengths, not just the number of borders or their maximum. Matching lengths are tested separately and each counted once. The entire word is always eight symbols; only candidate borders have lengths1 to7. One captured stake covers the whole word. Choose exponent1,2 or3 before drawing.

Gross multiplier=0.96×score^p/mean(score^p) for exponentp=1,2,3. The exact means are1.9296875,12.8828125,210.9921875. Each mode has expected gross credit96% of its captured stake. This is not a96% winning probability or a final-wallet guarantee. A square or cube does not multiply the score by two or three.

A new browser wallet starts at 1000 virtual coins. Settled integer balance and fractional payout carry are saved in localStorage. A gross credit is added to any saved fraction; the integer part is credited and the remaining fraction is carried forward. These coins have no cash value, deposits, withdrawals or prizes. Storage belongs to this browser and origin, not to an account or an external payment balance.

Only an idle balance below ten offers Free refill. Clicking it sets the balance to 1000; it does not add 1000 to the existing balance. The fractional carry is preserved. Refill is unavailable during settlement or an active automatic queue. Changing the stake cannot force a refill while the balance is ten or more. A previously saved zero balance remains zero after reload until the user clicks the available refill.

The game needs no login or personal-data form. That does not mean no personal data is processed. Pages request Google Fonts and a Statinside counter; hosting, CDN and third-party requests may expose IP addresses, device information, URLs and request times. Exact retention periods, cookie lifetimes, linking practices and anonymity have not been independently established here.

Exhaustive enumeration of256 words checks Border Length Ledger and its own formula. It certifies no external app, operator, licence, random generator, privacy, safety or payment capability. Previous words do not predict new independent symbols. No APK existence, signature, file size or approval has been established for the queried name.
