Know the limits before the first spin
Before you set a budget for a session, accept that the bonus round comes at random. Nobody can tell in advance how often The Dog House Megaways™ will trigger its free spins. The result of one session is random whatever the RTP, and the RTP of 96.55 describes the return over a very large number of spins, not the outcome you will see tonight.
Before you compare return figures, check which RTP version the game runs on this site. That detail is shown only in the game rules, so read them before your first stake. Versions can differ in their return and maximum win, and the rules set the figure that applies to you.
Before you aim for the top prize, be clear what the maximum win means. The game pays at most 12,305 times the bet, and that ceiling is reached very rarely. A large multiplier on one spin is possible, but it cannot be planned, and it is not a result you can expect from a session.
