H.O.R.S.E is a mixed game where multiple poker variants are played at set intervals. The letters for these mixed games are made up from the following:
- H: Texas Hold 'em
- O: Omaha Eights or better
- A: Omaha Hi
- R: Razz
- S: Seven card Stud
- E: Seven card stud Eight or better
There are several common variations of H.O.R.S.E mixed games such as H.O.S.E and S.H.O.E, but we try to offer some of the less played mixed games such as R.A.S.H., H.A.R, H.A. and H.O. Games progress in order of letters shown starting with Hold'em then Omaha and so on, at set timed intervals. For tournaments, game type changes every time the blinds go up and for ring games every 8 hands. The exception to this is in H.A. and H.O ring games where the interval is set to every 10 hands.
