Before your first spin on the reels
96.50 percent is the RTP of Sleeping Dragon, and it describes the return over a very large number of spins, never the outcome of one session. How often the bonus round comes is not known in advance. The result of one session is random, whatever the RTP, and this high volatility game can go long stretches without a bonus before a large win lands.
One RTP version, 96.50 percent, is listed for Sleeping Dragon. Which version runs here is shown only in the game rules. Check those rules before you set this return against a figure from another game, because the comparison only holds when the versions match.
x15,000 of the bet is the top win of Sleeping Dragon, which comes to A$150,000 at the example bet of A$10. Reaching that ceiling is very rare. Treat the figure as a ceiling on the payout, not as an expectation for any session.
