Before the first spin, what stays unknown
Before you place a bet, accept that the bonus round follows no schedule. Nobody can know in advance how often Free Spins or Coin Respin will start. The result of one session is random whatever the RTP. A long dry run tells you nothing about the next spin, and a short session can end with a large win or none.
Choosing a bet size is your first decision, so check which RTP version this lobby runs before you commit. Only the game rules state that version, and they are the place to confirm it. Read them once before your first spin, then play at a stake you can afford.
Before you chase the top prize, look at how rarely it is reached. The maximum win is the highest payout the game can produce, and it is reached very rarely. Treat it as a limit on what is possible. Set your budget before the first spin and keep to it.
