Equal hazards in the two halves
Choose 2, 4 or 6 hazards on a 4×4 board. Rows A and B together contain exactly as many hazards as rows C and D together. Each eight-cell half contains 1, 2 or 3 hazards respectively. All 64, 784 or 3136 legal layouts are equally likely. One random layout remains fixed for the round.
Initial and updated safe probabilities
With 2 hazards, each half contains one hazard and every cell is initially safe with probability 7/8. A safe first reveal from a 20-coin stake gives 20×0.97/(7/8), about 22.171 coins. If the first safe reveal is in the top half, an unopened top cell then has safe probability 6/7 while a bottom cell remains at 7/8. With 4 or 6 hazards, the initial probability is 6/8 or 5/8 respectively. Observations can change probabilities in different ways across halves.
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.

What is the stripe constraint?
Choose 2, 4 or 6 hazards on a 4×4 board. Rows A and B together contain exactly as many hazards as rows C and D together. Each eight-cell half contains 1, 2 or 3 hazards respectively. All 64, 784 or 3136 legal layouts are equally likely. One random layout remains fixed for the round.
How is value calculated?
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.
How do odds change after a reveal?
With 2 hazards, each half contains one hazard and every cell is initially safe with probability 7/8. A safe first reveal from a 20-coin stake gives 20×0.97/(7/8), about 22.171 coins. If the first safe reveal is in the top half, an unopened top cell then has safe probability 6/7 while a bottom cell remains at 7/8. With 4 or 6 hazards, the initial probability is 6/8 or 5/8 respectively. Observations can change probabilities in different ways across halves.
