KKFF queries and our own 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 fair binary symbols
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 finite virtual wallet
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.
Requests and privacy limits
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. We make no promise that technical data cannot identify or be linked to a person.
An app query is not a download
This website supplies no APK, installation package or verified KKFF app listing. The simulator works in the browser without installing separate software. File names, download counts, a padlock or a virus scan do not prove the identity or safety of a file. An unresolved publisher or source is a reason to leave a download uninstalled, not to disable device protections. We do not recommend a package or provide installation instructions.

No player answer, letter rearrangement or separate row stake affects the calculation.
Sum lengths of all proper borders?
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.
Equal, alternating and unbordered words?
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.
