High Card Flush
A couple of readers have asked about Galaxy Gaming’s new High Card Flush game, which has a few placements now, and may be picking up some steam. The game is pretty simple, where each player and the dealer receive 7 cards. Each hand is measured by its highest flush, where a flush is first ranked by its length (number of cards of same suit), then by its card values. Each player must Ante before the hand, then wagers a 1x-3x Play bet (depending on flush size), or folds. The dealer qualifies with a three-card, 9-high flush. If the dealer doesn’t qualify, the Play bets push, and the remaining Antes are paid even-money. If the dealer qualifies, the Ante and Play bets receive even-money action against the dealer hand.
As you would expect, collusion helps in this game. A Monte Carlo analysis shows that with 6 confederates, perfect knowledge of the dealt cards gives each spot at least a +7.3% edge over the house. But practically, you’d be lucky if you could even communicate the suit counts (number of cards of each suit) dealt. If you figure out a non-suspicious way of doing this, then the following simple strategy yields a +3.1% edge over the house:
| Flush Size | Play Bet |
|---|---|
| 1 or 2 cards | 1x for suit counts (9, 11, 11, 11) or (10, 10, 11, 11), else fold others |
| 3 card, Jack-high or lower | 1x for suit counts (9, 11, 11, 11) or (10, 10, 11, 11), else fold others |
| 3 card, Queen-high | 1x if lowest suit count is 9 or higher, else fold. |
| 3 card, King-high or better | 1x if lowest suit count is 8 or higher, else fold. |
| 4 cards | 1x |
| 5 cards | 2x |
| 6 or 7 cards | 3x |
where the suit counts 4-tuple is the sorted number of cards of each suit.

Wow that was fast work Steven! Thanks
what if only 3 player hands seen, i.e., your two next neighbors?
You need a full table (6 players) colluding to have a +EV edge in this game. Even with 5 confederates, you’ll still be -EV.
Anyone know of any SoCal casinos with this game? Played it in vegas and love it!
