Every title on the shortlist carries high or medium-high volatility, and that is not a coincidence. Games with frequent large multipliers tend to be built that way, and the published maximum win figures reflect it. High volatility means longer dry spells between meaningful returns, so a bankroll suited to a medium-volatility game can vanish quickly here even when the return figure looks respectable.
The ordering below is by published return, which is a narrow measure. If you weight how often you see a return rather than how large it can be, the ranking would look different. Read the volatility and maximum win columns alongside the return figure rather than treating one number as the whole story, and remember that none of these games can be played in a way that changes the published average.
