Royals only count on three-lines games, Max, anything else is cheating
Great. Now the NQAR thread will get inundated with 5 liners.
I suggest that Royals count if they're on at least 1/3 of the lines played with 4 held, at least 1/5 of the lines played with 3 held, or any hit on 2 or fewer held.
I'd also suggest that Sequential Royals always count, ascending, descending, whatever... if on a sequential royal game. (Standard rules apply if it's "only" 4000 coins instead of 50k.)
May the cards fall in your favor.
