Omaha 5 Cards Calculator

Omaha 5 Cards is a popular poker variant where players receive 5 cards and must use exactly 2 of them to make the best 5-card hand. This calculator helps you determine the probability of winning hands in Omaha poker by calculating the odds and equity based on your hand and the board cards.

What is Omaha 5 Cards?

Omaha 5 Cards is a variation of poker where each player is dealt 5 cards, and they must use exactly 2 of their cards to make the best possible 5-card hand. The remaining 3 cards come from the community cards on the board.

This variant is popular in home games and online poker rooms because it offers a different strategic challenge compared to traditional Texas Hold'em. The key difference is that players must choose which 2 of their 5 cards to use, adding an extra layer of decision-making.

Key Differences from Texas Hold'em

In Texas Hold'em, players use any number of their 2 hole cards with 5 community cards. In Omaha, players must use exactly 2 of their 5 cards with 3 community cards.

How to Use the Calculator

Our Omaha 5 Cards Calculator allows you to input your hand and the board cards to determine the probability of winning various types of hands. Follow these steps:

Enter the 5 community cards in the "Board Cards" field.

Review the results to understand your chances of winning.

The calculator will display the probability of making different types of hands, such as pairs, two pairs, trips, straights, flushes, full houses, quads, and straights flushes.

Formula Used

The calculator uses combinatorial mathematics to determine the probability of making different types of hands. The basic formula for calculating the probability of a specific hand is:

Probability Formula

P = (Number of favorable outcomes) / (Total number of possible outcomes)

For Omaha 5 Cards, the number of possible 5-card hands from 7 cards (2 from your hand + 5 community cards) is calculated using combinations. The calculator then determines how many of these combinations result in each type of hand.

Worked Example

Let's consider an example where you have the following hand and board cards:

Your Hand: A♠ K♠ Q♠ J♠ 10♠
Board Cards: 9♠ 8♠ 7♠ 6♠ 5♠

In this scenario, you have a straight flush (A♠ K♠ Q♠ J♠ 10♠) on the board. The calculator would show that the probability of making a straight flush is 100% because you already have all the cards needed for the straight flush.

For a less obvious example, if you have A♠ K♠ Q♠ J♦ 10♣ and the board is 9♠ 8♠ 7♠ 6♠ 5♠, the calculator would show the probability of making different types of hands based on the combinations of your 2 cards and the 3 board cards.
