Slots and RTP explained
Can the same physical slot machine have different odds at different denominations?
Direct answer
In some regulated markets machines have different approved payback settings; only the game's documented configuration can verify that for a specific machine.
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.
