A Joker dropping onto a specific cell multiplies the value of existing held coins. During the bonus round, Joker symbols leave a multiplier (starting at x2) on their position; if a second Joker lands in the same cell, the multiplier increases by x1 each time, potentially reaching very high values. It is, honestly, the most exciting part of the mechanic.
The Royal Bonus symbol appears on the second reel and is sticky during bonus rounds. When it lands, it collects the combined value of every coin currently on the grid, effectively acting as a sweep that can dramatically increase the round's total payout.
The Pile of Gold feature triggers randomly during any bonus game. When active, all bonus symbols on the grid receive a x2 multiplier, doubling their face value in a single event.
These special features do not change the negative expected value over time; they simply shift the win probability toward rare, high-end anomalies. A simulation study from the University of Turku (September 2023, cited in the Royal Joker research briefing) found that in high-volatility video poker simulations, only 5% of players remained in profit after 100 hours of play, while the majority experienced prolonged losing streaks.
Bonus Buy: purchasing instant access to the Hold and Win round
Where available, the bonus buy function lets you skip the base game and enter the Hold and Win round immediately for a fixed cost of 100x your current stake. This condenses the mathematical variance into rapid, high-cost events compared to natural base-game triggering. Industry metrics note that repetitive purchasing rapidly drains consumer balances compared to the buffering effect of standard base-game hits.
Industry guidance on bonus buy bankroll management (cited in the Royal Joker research briefing) recommends that a single bonus buy should not exceed 5 to 10% of the total session bankroll to avoid rapid depletion. Many regulated platforms disable the bonus buy function entirely to comply with responsible gambling limits. If you are a newer player, triggering the bonus naturally through base-game spins is the lower-risk approach.
