Purpose of the guide
The pages cover the demo rules, virtual wallet, storage and practical limits of the information. They are intended to help you understand this browser experiment. They are not a registration portal, deposit service or verification certificate for another website.
The original constrained board
A four-by-four board is chosen uniformly from legal placements of the selected 3, 4 or 5 mines. Within each row, mines form at most one contiguous block; an empty row is allowed. The board remains fixed during the round.
Exact support and return
The legal support sizes are 408, 986 and 1,704 for 3, 4 and 5 mines. At a current support of C boards, an eligible cell safe in S boards has conditional safe probability S/C. Its safe quote changes by C/S. Including the mine outcome, this preserves exact 96% expected gross return; it does not guarantee a session balance or a profitable collection.
How the interface works
Choose the stake and mine count while idle. Starting captures and debits one whole stake. Stake, mine count and restore are locked during the round; eligible cell reveals and sound remain available. There is no automatic round queue. Collection is a virtual settlement action, not an external transfer.
Persistence and limits
Settled whole balance and fractional carry are stored locally. An unfinished round is not resumed or refunded after reload. A low idle balance can be manually set back to 1,000. The restore control provides virtual coins only; it has no cash redemption function.
Information beyond the demo
The search term and this domain alone do not prove a third party’s licence, location, account service or financial arrangements.

Frequently asked questions
Do safe odds remain fixed?
No. Safe reveals filter the compatible legal boards, so each remaining cell’s conditional safe probability is recalculated.
When can I collect manually?
After at least one safe reveal, while the round remains active.
Does reload refund an unfinished round?
No. The unfinished round ends without refund or resume. Stored whole balance and fractional carry remain unless site storage is removed.
