Hidden timing of the bonus round
96.50% is the RTP of Sleeping Dragon, and it describes the return over a very large number of spins, not a single session. How often the Free Spins or the Respin Bonus Feature come is not known in advance. Two sessions at the same bet can end far apart, because the result of one session is random whatever the RTP.
Only one RTP, 96.50%, is listed for Sleeping Dragon. Which version Bizzo Casino runs is shown only in the game rules, so check there before you play for real money. This page gives the figures, but the game rules are the reference for the return.
x15,000 times the bet is the highest win Sleeping Dragon can pay, and it is a ceiling, not a target. Players reach it very rarely. High volatility means the bigger wins come in bursts, with long gaps between them.
