How often will the bonus round come?
Boss Bear has 30 fixed positions and 50 fixed win lines. How often the bonus round comes is not known in advance. The result of one session is random, whatever the RTP version of the game, so a higher RTP only changes the long-run average.
Six RTP versions of Boss Bear exist, and Winner Casino runs one of them at a time. The version in use is shown only in the game rules, and the table below lists what each one returns.
x25,000 the bet is the ceiling of Boss Bear, and at the A$100 highest bet allowed here that ceiling is A$2,500,000. A win at that level is reached very rarely, so treat it as a limit, not an expectation.
