Calculator Tool

Use the DD Poker Calculator Tool to run in depth hand analysis and calculate showdown outcomes. The Calculator Tool has many uses:

Calculate full pre-flop showdown odds, like they show on poker TV shows.
Find out why winner of AK suited versus pocket two's heads-up is essentially a coin flip (50/50).
Find out all the ways your hand can improve after the turn and river cards come.
Measure how your hand stacks up against all possible opponent's hands.

When you use the Calculator Tool from a game, it automatically loads the current cards on the table each time you open the window. The exception to this is if you change any of the cards or number of opponents to research other scenarios. In this case, the Calculator Tool will leave your settings as you left them. To reset the tool back to the current hand, click on any card and choose the "Load All Cards".

Hint: You can drag the calculator window outside the DD Poker window so you can keep it open as you play.

Picking Cards

Click the left or right mouse button while the mouse pointer is over any card for the Change Card Pop-up to appear.

Shortcut: You may CTRL click any face up card to clear it to a wild card "?".

Clear All Cards	Click Clear All Cards start over and reset all cards to a wild card .
Clear Opponents Cards	Click Clear Opponents Cards to only clear your opponents cards to a wild card .
Clear Community Cards	Click Clear Community Cards to only clear the community cards to a wild card .
Load All Cards	Click Load All Cards in Practice mode to load your hole cards, all opponents hands and the community cards.
Load My & Community Cards	Click Load My & Community Cards in Practice mode to load your hole cards and the community cards.
Opponents' Cards Face Up	In Practice mode, by default, the calculator tool loads all opponents hands as wild cards. If you wish, you can toggle Opponents' Cards Face Up so that the opponents' cards are displayed face up. The calculator will have far fewer combinations to calculate since it does not have to figure every possible hole cards your opponents can have. Be careful using this because you will learn your opponents hands! (Only available in Practice)

Showdown Calculator Tab

This tab calculates the win/lose/tie percentage of each hand against each other using the defined community cards (blank cards are wild). There are two ways to calculate this: Running all possible combinations or simulating trials with random samplings. When in Practice mode, your current hand and the community cards will automatically appear. Click the Run button to start the calculator.

Opponents	The calculator takes into account the number of players in the hand. This is important because the more people that are dealt a hand, the higher the odds more players will end up with a playable hand.
Simulate # Trials	This setting is used to get an approximate calculation based on random hand sampling when there are 6 or more wild cards not showing. The lowest setting of 25,000 gives only a rough estimation. You can increase the number samples for a more accurate calculation. (Range is twenty-five thousand to ten million).
All Combinations	Choose this setting if you wish to calculate the exact percentage with 5 or less wild cards. It is not practical to use this setting with 6 or more wild cards because of the amount of time it would take to calculate the billions of possible combinations. Use the Simulate setting for 6 or more wild cards. By default, the selection will change from Simulate to All when the number of calculations is below 2,000,000.
Run / Stop	Click the Run button to start the calculator calculation. Click Stop to cancel the calculation (you may wish to do this in simulation mode once you see the percentages have stabilized and are only fluctuating by less than a percent). You may also click the Close button to stop the calculation and close the Calculator Tool window.

What do the number of combinations mean? Cards that are unknown or not visible are called "wild cards". These could be community cards or your opponent's cards. When there is a wild card, the calculator will calculate all the possible outcomes and display a percentage for each player's chance to win, lose, or tie.

Note: The Showdown Calculator takes every possible hand combination into account when calculating. It does not figure that your opponent would have folded a poor hand like a 2 7 off suit, or that they would have more likely stayed in with a pair of kings. See the note on "uniform" distribution in the Hand Strength section below.

If there are no wild cards, there is only 1 combination, meaning everyone's hand is showing and there is only one possible result.

If there are multiple wild cards, then DD Poker uses a branch of mathematics called combinatorics to determine the number of combinations. We won't get into the details of the equation used to determine this, but rest assured DD Poker does the hard math for you.

As you add more wild cards in multiple hands, the number of possible combinations grows exponentially. As an extreme example, calculating 10 hands of wild cards and 5 wild cards on the board would have 60,281,548,319,469,636,261,129,060,633,600,000 combinations and take longer than the age of the universe to calculate! In cases like that, use the simulate option unless you have a really really really large amount of free time on your hands.

Flop Tab

Once you specify your hole cards and zero to two of the community cards, the Flop tab calculates all the possible hands you could have after the full flop is displayed.

Turn Tab

Once you specify your hole cards and three of the community cards (i.e., the flop), the Turn tab calculates all the possible hands you could have on the turn. This will help you figure out how many 'outs' you have to make a straight or flush.

River Tab

Once you specify your hole cards and three or four of the community cards (i.e., the flop or turn), the River tab calculates all the possible hands you could have on the river.

Hand Ladder Tab

The Hand Ladder tab shows how your hand, together with the current board cards, ranks against all other possible opponents' hands.

Hand Strength Tab

Once you specify your hole cards and at least three of the community cards, this tab shows the odds that your hand, together with the current community cards, is the best possible hand. Because the odds a particular hand will win diminishes as you face more opponents, the Hand Strength tab shows the odds versus 1 through 9 opponents. Using this you can see that pocket aces and a board of Kd 5s 10s wins 96.62% of the time against one opponent (heads-up) and only 87.16% against 4 opponents.

The Hand Strength item in the DD Dash board shows the same value on this tab, using the row for the number of opponents still left in the hand. The hand strength calculations assume your opponents hands are equally likely to have a poor hand as well as a good hand and the percentage is calculated based on all possible hands remaining. This is known as a "uniform" distribution. In a future version of DD Poker we will allow you to measure your hand strength against what your opponents are "likely" to hold.

Hand Group Simulations Tab

This tab displays wins, loses, and tie percentages of your hand compared to the groups of hands defined in "Hand Groups" in Options.

With one or two board cards defined, this tab shows how your hand does against random hands and the hands in all defined hand groups (see Hand Groups tab in Options) Because there are millions of possible 5-card board combinations, it simulates a random subset of them and tally's wins, loses and ties.

With three, four or five board cards defined, this tab shows how your hand, together with the current board cards, does against random hands and the hands in all defined hand groups. It then calculates and tally's wins, loses, and ties based on all possible remaining board cards. (practice only)
