Last Longer (Last One Standing) - 2 or more players create a Prop Bet on who lasts longer in an event.

Bankroll Challenge - The player sets a target bankroll amount and succeeds if they reach that bankroll within their set time frame.

ELO Challenge - The basic rule is almost identical to the Bankroll Challenge, but the difference is that your win is based on the achievement of the Goal Rating via all Spin & Gold games.
