The Simulator

Simulator Mode vs. Game Mode

Simulator mode is what we know from most equity simulators. We can enter ranges for multiple players and run equity simulations. We do not have any game parameters involved like betting, stack-sizes, pot-sizes etc. It is simple and it is quick and this will be the topic for this article.

In Game Mode we require a valid poker game including game parameters like betting, stack-sizes, pot-sizes. We have to ways of entering Game Mode:

1. We can import a valid hand history
2. We can build a new game using GAME BUILDER.

We can switch between the two modes at any time by clicking the toggle icon:

In this article we will talk about the Simulator Mode.


Simulator Mode

The Simulator let's us run equity simulations without the need of a hand history. The interface is similar to Game mode:

Let's do a walk-through of the features in the Simulator.


We can enter range for up to 6 players in the simulator. The syntax is standard Odds Oracle syntax with the addition of PJ Syntax postflop. Let's enter AA for Player 1:

As we can see Player 1 is now activated in the replayer.


For each player we can see the number of combos. Ranges in the simulator are independent of each other as is standard in equity simulators and also Odds Oracle. In other words, there are no card removal effects between ranges in the simulator. (We can verify this by entering AA for Player 2 and Player 3 and we will get the same number of combos.)

PokerJuice Ranges

The Simulator provides quick access to all the PokerJuice Ranges. Let's add another player and assign him a PJ 3bet ip 8% range:

We click the "2" icon and navigate us way through the ranges until we reach the PJ 3bet ip 8% range. We then select include. Notice that we have the option both include and exclude ranges.

We now have two active players in our simulator:


If we click the orange play button we run an equity simulation between active players and we see the results for each player.

Board + Dead Cards

We can also enter a board and dead cards:

We click the "B" icon and select QhJs8s:


Notice, that the number of combos have now changed for both players. Why is that?

Well, since three cards are now on the board these three cards have essentially removed from the deck. They can no longer be a part of either player's range. For instance, all the AA combos that include either of these three cards are no longer possible. This is why the number of combos go down for both players.


Let's try another board. But instead of selecting the board cards let's try a random board:

Hover over the board and select the Randomize icon at the bottom. Since we are randomizing chance are you will not end up with the same board as me but mine came out like this:

Let's randomize Player 1's holecards as well. We click the randomize icon for Player 1 a few times:

Notice that we can now step back and forth between the hands generated. At the top of the popup panel we can click the pencil icon to manually edit the hand. Randomizing is great for practicing equities.

To update the equities we click the orange play button.

Note: Equities do not auto-update in Simulator like we know it from Game mode. This is by design.


Saving range/simulations

When doing equity work we often want to save specific ranges or even entire simulations so that we don't have to start from scratch next time.

A Range is whatever we can enter into a single player's input field.

A Simulation is the combination of all players ranges, the board and the dead cards.

Let's start by saving this hand.

We place the cursor inside the input field for Player 1. We then click the Save range icon. We select Save Range.

We enter an appropriate name and click save. We can now load this range for any player:

We put cursor inside input field for Player 4. We then click the Load range icon. 

We navigate to the range we just saved and select Load range:

Player 4 now has the same hand as Player 1. This is totally fine in the Simulator where combos are not constrained by a single deck of cards. However, if we attempt to run an equity simulation we would receive an error.


Disabling a Player

Let's disable Player 4 so that we don't get receive an error:

We have two options if we want to disable a player:

  • Single-click the small disable dot we know from Game mode.
  • Double-click player icon next to the input field.

Both options disables the Player. The input is still in the input field but the icon is now grey - indicating the player is disabled. 


Range Distribution Module

RANGE DISTRIBUTION does not require Game mode parameters like the other modules, so we are able to use RANGE DISTRIBUTION in the Simulator. The other modules will only run in Game mode.



We have now covered the basic features of the Simulator. The Simulator is great for practicing equities and how different ranges hit different flops or hand vs. hand match ups. We can quickly go through a lot of flops and hands with the randomizers and we can even save the interesting ones. 

If some of the more advanced Game mode feature in PokerJuice are needed like street-by-street filtering og betting then I suggest building a quick game in the PokerJuice GAME BUILDER.
