Pump
Fifteen membrane panels. One pump. Fresh cells every bet.
House Edge: 2%
Pump shows one balloon with 15 numbered membrane panels in three rows of five. The button always tests protocol bit 0; there is no panel to choose. Difficulties 1–4 publish 1, 5, 8 or 9 burst cells and pay 1.05×, 1.47×, 2.10× or 2.45× on survival. Every pump is an independent bet paid to balance. The balloon returns to the same resting size after each result.
How to play
Pick a difficulty, then press Pump. There is no cell to choose: every pump tests the same cell of a membrane whose burst cells are scattered again first. A surviving pump pays its gross return into your balance, and pumping again stakes exactly that amount. The balloon returns to its resting size every time, because nothing accumulates between pumps.

Fairness
Every settlement reveals all 15 panels, including bursts on a loss. A set hazard bit means a burst cell; bit 0 decides the pump. All cells are seeded again for the next bet. The receipt retains the full mask, tested panel, stake and settlement identity. Every difficulty has 98.00% RTP and 2.00% house edge per pump, not per repeated sequence.
