Introduction
- Casino Oasis Stud Poker Analyzer ( ) by Blitz (c) 2004-2019 (c) 2004-2019.
- Oasis Poker takes the classic game of Caribbean Stud Poker and adds a new dimension. The player is allowed to exchange cards before choosing whether to raise or fold. However, the player must pay for the right to do this. Apart from this Oasis Poker is very similar to Caribbean Stud, with the goal being to have a better hand than the dealer.
Oasis Poker is a variation of Caribbean Stud Poker. The rules of Oasis Poker are the same as Caribbean Stud, except the player is allowed to exchange cards before the raise/fold decision, for a price of course. The game can be found mostly in eastern Europe, northern Africa, and Internet casinos using Galewind Software. Following are the complete rules.
Rules
- The player makes an ante wager plus optional side bonus side bet.
- Player and the dealer get five cards each. All cards are dealt face down, except one dealer card is exposed. The player may examine his own cards but sharing of information is not allowed.
- The player has the option to switch one card of his choice for the next card in the deck. There is a fee to do this, equal to the ante wager. This fee is non-refundable.
- The player may switch one of more cards. The price for switching depends on the number of cards switched, as follows:
- One card: 1x the Ante.
- Two cards: 2x the Ante.
- Three cards: 3x the Ante.
- Four cards: 2x the Ante.
- Five cards: 1x the Ante.
- If the player switches all five cards, then he must raise.
- The player may either fold or raise.
- If player folds, then he forfeits his cards, ante bet, and side bet (if made).
- If player raises, then he must make a raise wager exactly equal to twice the ante.
- The dealer will turn over his other four cards.
- The dealer must have an ace/king or higher to qualify. In other words, the lowest qualifying hand would be ace,king,4,3,2.
- If the dealer does not qualify then the player will win even money on his ante wager and the raise will push.
- If the dealer qualifies and beats the player both ante and raise will lose.
- If the dealer qualifies and loses to the player then the ante will pay even money and the raise according to the Raise Pay Table below. Other pay tables have been known to exist.
- If the player and dealer tie then both the ante and raise will push.
- The bonus bet win will be entirely based on the poker value of the player's original hand.
Oasis Stud Poker is a casino adaptation of the game of Stud Poker and is a very simple yet exciting game to play. Casino Kigali Oasis Stud Poker takes the basic concepts of the game and allows players to play against the bank rather than against each other. Oasis Poker is a variation of Caribbean Stud Poker. The rules of Oasis Poker are the same as Caribbean Stud, except the player is allowed to exchange cards, for a price of course. Under the version addressed in this page the player may not fold if he chooses to switch cards.

Strategy
I have never quantified a perfect card switching strategy. My program makes a perfect decision every time by analyzing all possible combinations of the replacement card and all four dealer cards. However, from running through some test hands I believe the following strategy is close to optimal.
The player should switch one card with any of the following:
- Four to a straight flush and royal flush, even breaking up a pair
- Four to a flush with no pair.
- Four to an outside straight with no pair.
The player will sometimes switch with any of the following:
- Four to a flush with a low pair (depends on the pair and dealer's up card).
- Four to an inside straight with no pair (depends on the inside straight and dealer's up card).
My apologies for not being more specific. In my view there, is not enough demand for the information to warrant doing a more detailed strategy.
Do not switch with two pair or three of a kind.If the casino allows switching two or more cards that option should never be taken.
Once the switch decision has been made the player can follow Caribbean Stud Poker strategy when deciding to raise or fold.
Odds
The following return table is based on the pay table above. Other pay tables are known to exist, which would change the odds.

The lower right cell shows a house edge of 1.04%.
After possibly switching and raising, the average final bet, including the switching fee, will be 2.183772 units. The element of risk is thus 0.475%. On average the player will switch 8.4% of the time.
At Internet casinos using Galewind Software there are some rule changes. There the player may switch one to five cards, for the price of one ante per card, and a full house pays 6 instead of 7. Under those rules the house edge is 1.204%, the average final wager is 2.184 units, and the element of risk is 0.55%.
Side Bet
I indicate the odds of the side bet in my Caribbean Stud Poker section. Some casinos have been known to base the side bet on the hand after switching. This can be a very good rule for the player. However, if you see it, you're on your own.
Belgium Variant
In Belgium the player is allowed to switch a card, but if he does, he forfeits his option to fold. That version of the rules is addressed in my section on Belgium Variant of Oasis Poker.
Nicaragua Variant
Oasis Poker is very popular in Nicaragua. It seems to have more placements than any other game. However, they call it Caribbean Stud Poker. The pay table is the standard one for the original hand. However, it is depressed if the player switches a card, which still costs the price of the Ante bet.
This variant has never been analyzed, as far as I know.
Nicaragua Variant Pay Table
| Hand | Original Hand | After Discard |
|---|---|---|
| Royal flush | 100 | 50 |
| Straight flush | 50 | 20 |
| Four of a kind | 20 | 10 |
| Full house | 7 | 5 |
| Flush | 5 | 4 |
| Straight | 4 | 3 |
| Three of a kind | 3 | 3 |
| Two pair | 2 | 2 |
| All other | 1 | 1 |
As a variant of the Nicaragua variant, the Palms casino in Managua lets the player buy a sixth card for the price of the Ante, as opposed to discarding. This, too, has not been analyzed (sorry).
Finland Variant
Oasis Stud Poker Tournaments
