Slots and RTP explained
What happens to a progressive jackpot when its game is removed from a casino?
Direct answer
Regulators and operators may require transfer, payout or another approved treatment; there is no universal rule.
How to use this answer
A definitive win, loss, void or refund cannot be established from the question alone. Identify the operator, the exact market, the date and the relevant official result, then check the rules that applied to the bet.
Return-to-player and volatility are statistical properties, not promises for an individual session. A streak or a near miss does not establish that a particular spin is more likely to pay.
