There are lots of different versions of video poker such
as
Jokers wild - has one or sometimes 2 jokers that are wild
(i.e. you can use as any card you want). This obviously
gives you a better opportunity to get a good hand, but the
payouts are adjusted accordingly.
Deuces Wild - as above but with 2s wild (i..e. 4 wild cards)
Aces & Faces - like Jacks or better but different payouts
for 4 Aces and 4 of the same picture card (faces)
Tens or Better - like Jacks or better but there's a payout
for a pair of 10s, but the higher hands payouts are reduced
accordingly
Multi-Hand - there are multi-hand versions of most of the
different variations. Multi-hand video poker works by giving
you one initial hand on which you choose what you want to
keep and discard. It then plays out that hand multiple
times with different changed cards. So if your first
hand is good - it gets replicated many times. Can
be a lot of fun.
