77FF: Mines Rules for Pakistan

One diagonally connected group

Choose 3, 4 or 5 hazards on a 4×4 board. All hazards form one connected component using diagonal corner-to-corner steps only. Horizontal and vertical edges do not connect hazards. Every hazard is reachable from every other hazard along diagonal steps; all lie on the same checkerboard colour. All 32, 50 or 52 legal layouts respectively are equally likely, and one stays fixed throughout the round.

What Pakistani Players Should Check

Before playing, confirm that 77ff is accessible and legal in your area. Since gambling is restricted by national law, ensure you are of legal age. Check if the operator supports PKR for future deposits, though this demo is free. Verify if they accept JazzCash or Easypaisa by visiting their official site. For safety, read their terms carefully. Key checks include:

• Confirm local gambling legality in Pakistan.
• Verify if JazzCash or Easypaisa are supported.
• Check if PKR is the primary currency.
• Ensure responsible play limits are clear.

Initial and updated safe probabilities

With 3 hazards, a corner is initially safe in 29 of 32 layouts, an edge cell away from a corner in 27 of 32, and a central cell in 21 of 32. From a 20-coin stake, a safe corner gives 20×0.97/(29/32), about 21.407 coins; a safe centre gives about 29.562 coins. Observations update compatible layouts, so later odds can rise or fall. The initial probabilities are not uniformly 13/16.

Exact conditional value

Live value starts at 0.97 times the virtual stake. A safe reveal divides it by that cell’s exact conditional safe probability among the remaining compatible legal layouts. A hazard ends the round with zero return. Reveals change knowledge, not the hidden layout.

Collect and eligible choices

Collect is available after a safe reveal. Proven hazards are unavailable; proven-safe cells have probability 1 and add no value. A choice with next value above 1000 times stake is unavailable. When no eligible uncertain choice remains, the current value is banked automatically. The guard is not a promise that 1000×stake can be reached.

Persisted wallet and manual refill

Settled balance and fractional payout carry persist in localStorage. Reloading during a round ends it without refunding its already deducted stake. Outside a round, refill restores 1000 coins when balance is below the smallest stake; it does not add 1000 or reset fractional carry. Hazard count, stake and refill are locked during play.
