Accept that the bonus timing stays unknown
Plan your session knowing that when the bonus round arrives is never shown in advance, and that any single session can end ahead or behind whatever RTP the reels run at. Each spin is independent, so a long dry spell tells you nothing about the next one.
Check the game rules inside the slot before you stake anything: the payout percentage the reels here actually run at is stated there, and not on this page, so a version running at a slightly different figure is possible elsewhere.
Treat the x5,000 maximum win as the roof of the game, not a target you can plan around. Reaching it takes an exceptional run in the bonus round, and most sessions finish far below that ceiling.
