Game Board and Support
Row No 101 uses a four-by-four board. The board layout is drawn uniformly from all legal boards that satisfy the exact support rule: no row contains the contiguous pattern 101. This constraint defines a finite support set. Draws are uniform over that support, not over all unconstrained boards. The chosen mine count and public constraint define an exact finite board support. Each safe reveal filters the support.
Payout and Settlement
After a safe reveal, the gross cashout is calculated as 0.96 × captured stake × initial support size / current compatible support size. Mine returns zero. Cells with zero conditional safe probability are disabled. Cells whose safe quote would exceed 1000 times stake are disabled. When no eligible cell remains, the current quote is banked automatically.
Controls and Modes
The game offers a four-by-four board with mine count choices limited to the exact nonempty support configurations in the source. Captured stake and mine count are locked throughout the round. Sound remains available. Manual bank becomes available only after at least one safe reveal. There is no auto queue; manual idle-only refill is the only refill method.
Wallet and Persistence
The initial balance is 1000. Fractional carry persists across settlement, refill and reload. A manual refill while idle below 10 sets the integer wallet to exactly 1000. Settled balance persists locally including zero. An unfinished round ends without refund or resume when reloading. Stake, mine count and refill are locked while the round is active. Eligible reveal cells and bank remain available; sound remains available.
Privacy and Storage
Source uses browser localStorage for settled demo balance and fractional carry. This does not establish anonymity or exclude other processing. The template declares a Google Fonts stylesheet. Actual browser request capture is pending; this is not a claim that other requests or processing are absent. There is no demo account flow or demo payment flow.
Audience and Limits
The 18+ label is this guide's own intended audience policy, not a claim about local law or an implemented age gate. Virtual coins have no cash value. This demo does not certify or reproduce any outside product.
Frequently asked questions
Is V78 the official operator?
The queried brand V78 is unverified as the game operator. This demo belongs to this independent guide and does not certify or reproduce any outside product.
How does the board support work?
A four-by-four Mines board is drawn uniformly from all boards with the selected mine count satisfying the exact public support rule: No row contains contiguous pattern 101. Draws are uniform over that support, not over all unconstrained boards.
What happens on reload?
An unfinished round ends without refund or resume. Settled balance persists locally including zero. Fractional carry persists across settlement, refill and reload.
