Play Pressure Vessel ("The Overpressure Ladder") free, at its real house edge of -2.00%. No deposit and no real money — the chips are simulated, but the odds are the ones a real floor runs.
Cash-out pays 0.98/q^n; the 2% is charged once, not per pump. That is the whole mechanism: not luck, not a losing streak, just a rule that pays you slightly less than the true odds every time it resolves. Played long enough, the outcome is not in question.
You start with $1,000 and the deed to your own home. When Pressure Vessel ("The Overpressure Ladder") grinds the balance down you can mortgage that deed to keep playing, and when the collateral is gone the house is foreclosed and auctioned.
