Jacks or Better isn’t a term or casino jargon; it refers to a variance of popular video poker game called Jacks or Better.
In recent years, as online casinos became more popular, video poker has resurfaced and software providers have created numerous variances of the game, Jacks or Better being one of the most popular ones. The gameplay is relatively simple and similar to other video poker variances, while the most significant difference is the paytable.
As the name suggests, to win, players must land a pair of jacks or anything above, such as queens, kings, and aces, while you won’t win if you land anything between a pair of deuces to pair of tens. Furthermore, the game includes every other winning poker hand combination, such as two pairs, three of a kind, straight, flush, full house, four of a kind, straight flush, and royal flush.
