Known rules, unknown sessions
Choosing your stake on Wild West Gold means accepting that nobody can tell in advance how often the bonus round will come. The result of one session is random, whatever the RTP. The same bet can end a session with a loss or a win far above the stake, and no figure on this page changes that for a single visit.
Before you start a session, open the game rules and find the RTP version this lobby runs. Only the rules show that version, so a figure quoted elsewhere may not match the one you play on this site.
Plan your stake around the session you can afford, and read the maximum win as a ceiling. It is reached very rarely, so no session should be planned around it. The ceiling is a multiple of the bet, so it moves with the stake you choose.
