Board rule
The board has 16 cells, numbered left to right across four rows. Choose 3, 4 or 5 hazards before starting. The game samples one complete layout uniformly from 68, 72 or 24 permitted layouts, respectively. That layout stays fixed throughout the round.
Safe cells connect through horizontal or vertical neighbours. They must remain connected even if any single safe cell is removed. This constraint changes the chances from those of an ordinary board with independently placed hazards.
Conditional probabilities
Each cell displays its conditional chance of being safe among layouts compatible with the revealed safe cells. Percentages are rounded to one decimal for display; the calculation uses the full ratio. Already revealed cells, proven safe cells and proven hazards are disabled.
The gross multiplier is 0.97 × original layout count ÷ remaining layout count. It starts at 0.9700×. A safe pick divides the previous multiplier by that cell’s safe chance. A hazard ends the round with zero returned coins.
Collection and settlement
After at least one uncertain safe pick, Collect returns the current gross value. A safe pick that leaves no uncertain cells triggers automatic collection. Stake and hazard settings, restoration and a second start are locked during play; sound remains available.
Settlement credits the whole-number part of stake × multiplier + saved fractional carry and saves the remainder for later rounds. The multiplier includes the stake; it is not a profit multiplier. A losing round returns zero and preserves the saved fraction.
What the simulations show
The mathematical expected gross return is 97% in the uniform-layout model for strategies using the revealed information and eventually collecting or losing. This is not a 97% chance of winning or a promised result for a session. Abandoning an unfinished round forfeits its possible return.
Nine saved simulations used 1,000,000 rounds each, covering three hazard counts and collection depths one, two and three. Observed gross returns ranged from 96.668% to 97.142%, rounded to three decimals here. Those observations support the model; they do not replace its exact expectation. Whole-coin credits can differ from gross values because the remainder is carried forward.
Limit and user experience
The code includes a guard against a prospective multiplier above 1,000×. However, these supported layouts can reach at most 65.96×, 69.84× and 23.28× for 3, 4 and 5 hazards. The guard is therefore unreachable in this demo and does not set an attainable target or protect a stake from loss.
Frequently asked questions
How is the multiplier calculated?
It is 0.97 times the original number of layouts divided by the number still compatible with revealed safe cells. It includes the original stake, rather than showing profit alone.
Can the 1,000 × guard be reached?
No. Supported layouts reach at most 69.84 × across the three modes. The code contains the guard, but it is unreachable here.
Is 97% a guaranteed return?
No. It is the expected gross return under the uniform-layout model, not a win probability or promised session result. An abandoned round forfeits its possible return.
