Table Games
Diamond Jim’s Casino spreads 5 table games: 3 Card Poker, Blackjack, EZ Baccarat, Fortune Pai Gow Poker, and Ultimate Texas Hold’em.
Blackjack anchors the standard side of the pit, with EZ Baccarat as the no-commission format.
Pai Gow Poker is the split-hand format on the progressive side of the floor.
Ultimate Texas Hold’em is the multi-street raise-or-fold progressive variant. EZ Baccarat pushes the banker bet on a three-card total of seven rather than charging a 5% commission. All games operate under California’s player-banking model for licensed card rooms.

Poker Room
Diamond Jim’s Casino runs a 13-table poker room with NL Texas Hold’em, Omaha, and Texas Hold’em. A 13-table room is a mid-to-large operation for a California card room outside the major metropolitan markets. The Omaha spread gives the room game variety beyond the standard Hold’em-only format that smaller California rooms typically offer.
For Kern County players, Diamond Jim’s is one of the larger live-poker options in the region. Specific stakes, tournament schedules, and daily game availability should be confirmed with the room before a poker-focused visit.
