The actual simulator rules
One whole captured stake launches two independent twelve-row fair balls. Each lane index is its right-step count plus one, between one and thirteen. Raw score is the product of the two indices when their greatest common divisor is one; otherwise zero. The pair settles once after both balls finish. Six separately priced pairs mean at most twelve visible balls.

Scope of this independent guide
fall2.info publishes editorial pages and its own Coprime Pair Plinko browser simulator. A matching name or search query establishes no outside operator, official domain, licence, app, commercial catalogue, support contact or regional availability.
The simulator uses free virtual coins with no cash value. There are no deposits, withdrawals, commercial accounts or prizes here. Its results establish no external game mathematics, financial safety or commercial affiliation.
Exact weighted expected gross return
For each lane pair i,j from1 to13, probability is C(12,i−1) × C(12,j−1) / 2²⁴. These169 pairs are not equally likely. Low, Medium and High use weight √s, s and s². Gross credit is one whole captured stake ×0.96×weight / exact mean weight. All modes have exact96% expected gross return including the stake. Zero scores pay zero; modes do not change positive-score probability. No row shares or mid-path payments apply.
Captured settings and local wallet
A new wallet starts with1000 virtual coins. Choose10,20,50 or100 per priced pair. Launch deducts one full stake and captures stake and mode. Up to six priced pairs, twelve visible balls, may be active. Both balls finish before the one pair result is credited. Future control changes leave active settings intact. Settled balance and fractional-credit carry persist in localStorage. Auto10 queues ten pairs; Stop cancels future launches. Refill locks while any launch or queue remains active. While idle below10, optional refill sets balance to1000 and preserves carry. Reload does not replenish settled funds; refill is not automatic.
Stop future launches without chasing results
Stop cancels future automatic launches while active results settle under their captured settings. Closing the page ends participation. A virtual result creates no obligation to recover an earlier wallet balance.
Increasing stake scales debit and possible credit without raising expected return per coin. Mode changes do not raise positive-score frequency for a fixed probability condition. Choose a stopping time independently of the last result.

How does local storage and external requests work?
The browser retains settled balance and fractional-credit carry as local game state. These records are not an online account and provide no recovery or device synchronisation service. Clearing site storage can remove them; cache deletion alone may not do so. Pages request Google Fonts and a Statinside analytics script. Server/CDN logs and external requests may expose IP address, browser, device and request details. No anonymity, cookie lifetime, absence of profiling or complete third-party processing description is established. Having no personal-information form does not establish that browsing creates no personal data record.

How does worked scoring examples work?
Lane indices four and nine score36; four and eight score0. Two all-left paths give indices1 and1 and score1. Two all-right paths give13 and13 and score0. Lane indices are right counts plus one, not signed horizontal positions.
How does limits of external claims work?
No outside business identity, official domain, commercial safety verdict, licence, financial service or support channel is authenticated here. A logo, search ranking, name or professional interface does not establish these facts. HTTPS encrypts transport to a selected host; it does not certify the host business. The simulator cannot test external responsiveness, commercial payouts, accounts, funds or transactions. No commercial testing history, regulator endorsement or named editorial team with verified contacts has been established for these pages.
How does browser play without an operator account work?
The simulator requires no email, password, one-time code or identity document. Its local wallet is not a commercial account. This guide has no operator login, reset link or account-recovery service. No authenticated external login or recovery procedure is supplied. A matching name and padlock cannot authenticate a login page. The guide requests no passport, selfie, bank statement or credential for recovering funds or access.
