Unpredictable timing and session results
Deciding how long to play Big Bass Raceday Repeat starts with one fact: the bonus round does not arrive on a schedule. How often it comes is not known in advance, and the result of one session is random whatever the RTP. A long run of spins can end with a large win or with an empty balance, and no earlier spin predicts which.
Checking which RTP version Bigwin Casino runs starts in the game rules, because that is the only place it is shown. Read that section before staking real money. The version listed there sets the long-run return on every bet, while the spins you see on screen tell you little about it.
Chasing the top prize means accepting a ceiling that is reached very rarely. The maximum win of Big Bass Raceday Repeat is a multiple of the bet, so the money figure rises with the stake you pick. Plan for ordinary sessions, and treat the top prize as a rare outcome you cannot schedule.
