Unknown bonus timing and single-spin results
Deciding how much to stake on The Dog House Multihold depends on a number no one can know beforehand: how often the bonus round arrives. Each spin is random, so the result of one session is random too, whatever RTP version the game runs. A dry run does not make a bonus due, and a quick win does not signal one soon.
Checking the RTP before you bet means opening the game rules. Those rules are the only place that shows which of the two RTP versions this game runs, so a percentage seen elsewhere is not enough to go by.
Planning around the top prize means reading the maximum win as a ceiling, not a target. The maximum win of The Dog House Multihold is 9,000 times the bet, and it is reached very rarely. No one can say in advance whether a given session will come near it.
