Set your budget, then open the reels
Before you place your first bet, know that no one can tell you when the bonus round will land. Its timing is not known in advance, and the result of one session is random, whatever the RTP of the version you play. Two sessions with the same bet can end in very different places, so plan your money for the session, not for a particular feature.
Open the game rules before you bet, because only there is the RTP version this casino runs shown. The version named in the rules is the one to trust, not a figure you remember from elsewhere. Every RTP is a long-run return across many rounds, so one session can still land well below or above it.
Read the maximum win as a ceiling, not a target. Brick House Bonanza's maximum win is x10,000 of your bet, which is A$50,000 at the top example bet of A$5, and very few rounds reach it.
