A Search Name Does Not Establish an Operator
This independent guide has not established an operator, official business address, licence, application, support channel or financial service associated with 1PRA1. A matching name or logo is a lead rather than evidence of ownership. The guide provides its own original Border Relay browser simulator, with free virtual coins and no customer account. Its rules and conditional-average calculation do not reproduce or certify another product.
Eight Independent Symbols, Sampled Once
At the start of a round the browser selects one complete hidden word of eight independent symbols, each uniformly A, B or C. All 6561 possible words have equal probability. Symbols reveal one at a time; later collection choices do not replace the word or redraw its symbols. At the end, the raw reward is the greatest proper prefix length that matches a suffix of the COMPLETE eight-symbol word. Proper means shorter than the whole word; overlap is allowed. If no nonempty border exists, the reward is zero.
A Border Can Overlap
The word AAAAAAAA has reward seven, because its first seven symbols match its last seven. ABABABAB has reward six: ABABAB is both its prefix and suffix. AAAAAAAB has reward zero, because any nonempty prefix starts with A while every suffix ends with B and no matching prefix/suffix is possible. An on-screen comparison of the symbols revealed so far illustrates a prefix border; it is not the current quote or a final reward for the still-hidden whole word.
The Quote Averages Every Possible Completion
The exact unconditional mean terminal reward is 4395 divided by 6561, approximately 0.66986739826246. At a revealed prefix, average the whole-word rewards over all equally likely completions still consistent with it. Divide that exact conditional mean by the unconditional mean and multiply by 0.97 to obtain the collection quote. The quote can rise, fall or become zero; zero ends the round immediately. Its maximum possible value is approximately 10.13633447098976. A currently visible border length is not an extra multiplier or a substitute for this conditional average.
A Whole Captured Stake and Saved Free Coins
Choose ten, twenty, fifty or one hundred free virtual coins before starting. One whole captured stake is charged for the round. The wallet initially holds 1000 coins. Settled balance and fractional-credit carry persist in browser localStorage, so reload does not reset those values. While idle with fewer than ten coins, manual refill sets the balance to 1000 and retains carry; it does not add 1000. An unfinished round is not recovered or refunded on reload. Keep active play open until settlement. Ordinary cache deletion may leave localStorage intact.
Browser Storage and External Requests
Fonts are loaded from files hosted on this site. The guide has no customer registration, payment or identity-document form. That does not establish anonymous technical requests. Statinside requests, and server or CDN logs, may expose IP, device and request information. Complete third-party processing, retention, cookie lifetimes and anonymity are not established. LocalStorage is distinct from cookies, cache and access logs. Check what a browser site-data removal action actually covers; deleting local values cannot restore earlier progress. This page makes no assurance that no profiling or other personal-data processing occurs.
Frequently asked questions
What is 1pra1?
Free virtual coins · no prizes. Eight independent uniform A/B/C symbols form a word. Terminal reward is the longest proper prefix that equals its suffix; overlap is allowed. No nonempty match means zero reward. The quote is 97% of the conditional expected terminal reward divided by its initial mean. It can rise, fall or become zero. A zero quote ends the round. Auto pays the whole first crossing quote; a positive final quote settles automatically.
Is a business behind 1PRA1 verified?
No operator, official address, licence or application associated with the query has been independently established here.
What is the terminal reward?
The length of the largest proper prefix matching a suffix of the complete eight-symbol word, with overlap allowed; zero when none exists.
Is the visible prefix-border length the quote?
No. It is an illustration. The quote uses the exact conditional average of whole-word terminal rewards over all remaining possible completions.
How is the collection quote calculated?
It is 0.97 times exact conditional mean terminal reward divided by the unconditional mean of 4395/6561.
Does 97% mean a win guarantee?
No. It is exact unrounded expected gross credit for permitted stopping policies, rather than winning frequency or a session promise.
