Mega Joker — Full Review
Mega Joker has the highest RTP of any NetEnt slot at 99% — and one of the highest RTPs available at any UK-licensed casino. Two-tier 5x3 structure with a Super Meter mode. Best used with max bet to access the Super Meter. Low volatility.
Mechanic: Classic
Mega Joker uses the Classic mechanic — one of the defining features of this title's volatility profile and win distribution. This mechanic type tends toward frequent small wins.
Buy Bonus
Mega Joker does not include a Buy Bonus feature. Entry to the bonus round must be triggered naturally through gameplay.
