Two draws at the case ace, with every 2, 3 and 4 in the deck also live as a 400-coin kicker, beat a sure 9 coins by a wide margin. The same five cards make a three-game staircase, all solved exactly: on 9/6 Jacks or Better keep the full house (9.0000 vs 4.3080 for the aces); on 10/7 Double Bonus breaking it barely wins (10.1147 vs 10.0000); on Double Double Bonus it wins by 3.72. The cards never change — only the top of the paytable does.
