A dry spell before the Gold Spins
The 5x3 grid of Drill that Gold gives no clue when a bonus will land. How often the Gold Spins or the Drill Feature appear in a session cannot be known before the first spin, and the result of one session is random, whatever RTP version you play.
96.45% and 96.49% are the two RTP versions of Drill that Gold. Which version is running appears only in the game rules, so read them before you start a session. The gap between them is small, but the table shows its cost in money.
x5,000 the total bet is the maximum win of Drill that Gold, a ceiling reached very rarely. It is a limit on the top prize, not a figure to plan around. At the highest bet of A$125, the same ceiling reads A$625,000.
