Double Double Bonus Poker pays escalating premiums for four aces with a 2-4 kicker (2,000 coins at max bet), making it the highest-variance mainstream video poker game RTG offers.
The Kicker Economy
Because so much return is packed into kicker quads, two-pair hands pay only even money and sessions swing hard. Correct strategy holds a lone kicker with three aces and breaks two pair for a high pair of aces in specific spots — errors here are costly.
Who It Suits
Players chasing jackpot-like hits inside a ~99% return framework. Bankroll requirements are materially higher than Jacks or Better for the same stake.
