Accounts, deposits and withdrawals
The demo has no account registration, sign-in, deposit or withdrawal flow. Its virtual coins have no cash value and cannot be exchanged or withdrawn. Refill changes only the local demo wallet; banking collects only the current round’s virtual quote. These controls do not verify any outside bank, card, payment gateway, processing time or commercial service associated with the query.
Integer wallet and fractional carry
The initial virtual balance is 1,000. At settlement, the game adds any previously saved fractional carry to the gross quote, pays the integer part into the wallet and saves the remaining fraction separately. Carry is a payout remainder, not a fee or fractional wallet balance. While idle with a balance below 10, manual refill sets the integer wallet to exactly 1,000 and preserves carry. Refill is not available during an active round.
Gross quote and a worked example
After a safe reveal, the game retains only boards consistent with all safe cells revealed so far. Gross quote = 0.96 × captured stake × 370 / remaining compatible boards. Gross includes the stake; net change is gross minus the stake. A mine pays zero gross. Revealing the top-left cell first and finding it safe leaves 269 compatible boards, so the quote is about 1.3204× stake.
Reloading and local persistence
The integer wallet, including zero, and the separate fractional payout remainder persist in this browser’s localStorage. The stake deduction is saved when a round starts. Reloading an unfinished round does not resume it or refund that stake: the reduced balance remains saved. There is no account recovery, cross-device synchronisation or saved active-round state. A settled balance can persist across ordinary reloads.
What the browser stores
The demo saves its integer wallet and fractional payout carry in localStorage. Clearing cached files may leave this site storage; clearing the site’s stored data can remove the previous balance. Local storage alone does not establish anonymity or show that no other data are processed. This guide does not state an outside operator’s retention period, profiling practices, encryption policy or cookie lifetime.
Scope of this independent guide
This guide explains its own virtual-coin browser demo on f61.top. An outside operator, business identity, licence, official app or payment service for the queried name has not been established. The source-observable game and wallet rules described here do not verify an outside service or provide a verdict on its reputation.
Frequently asked questions
Can virtual coins be withdrawn?
No. These demo coins have no cash value or payment flow.
When can I refill?
While idle with a balance below 10, manual refill sets the integer wallet to 1,000 and preserves fractional payout carry.
What is fractional carry?
It is the separate fractional remainder after an integer payout, saved for a later settlement. It is not a fee.
