Jacks and Back
Jacks and Back: If no player can open with a pair of Jacks or better, then the game is played as Lowball, with a draw and final betting round. A less popular version of this game states that on the first hand, if no player can open with a pair of Jacks or better, than the game is re-dealt as Queens or Better, Trips to Win.
If nobody has Queens or better to open, then it becomes Kings or Better, Trips to Win, then Aces. After that, if the game continues, then it is back to Jacks or Better, Trips to Win.
