A powerful application to consult, shape and study your poker ranges in a few clicks. This is the objective of Rangor, the project founded by Pierre Merlin. Better known on the rooms and forums as "L'enchanteur", this professional player has launched with two collaborators the first application specifically dedicated to the study of poker ranges (that is, the range of possible hands in a given situation). His sidekick Kevin Goillot, aka "Dromz", supported him with his knowledge of GTO and solvers, while Neil Siguerdidjane was in charge of the programming part, in order to propose an aesthetic site and an intuitive operation

The concept

Lovers of ranges and pre-flop play will be delighted with this software. Rangor provides an interactive experience to help players advance their understanding and use of ranges. The application allows you to simulate every conceivable spot and associate the best ranges with it

For each spot selected, Rangor also provides a number of useful information to explore and understand the range of hands in depth, such as a breakdown of the types of combos that make it up. A graph also allows you to visually observe the types of action possible for each depth of stack with a given hand.

introduction to rangor software

Rangor offers a number of graphical tools, for example here, a bar chart to understand the different possible actions and their frequency, according to the depth of one's carpet.

The statistics provided are refined and updated with the latest solvers available to ensure the highest level of accuracy

Rangor is also a useful, accurate and complete classification tool for players who want to clearly define their pre-flop ranges according to all the objective parameters that a poker player must take into account: table format, position, depth

How does it work?

View mode

To consult your ranges in a few clicks, first go to the "View" tab. The interface proposes to select a format (8-max, 6-max or HU), before creating the spot to study

On the virtual poker table, it is possible to simulate the action of a hand:

A click on the player who will raise first, another on the depth of his stack, and a first range appears automatically: the opening range from the clicked position. Clicking on a second player again brings up the range he will play against against the first player.

Example: Left click on UTG, left click on BTN, left click on 30BB and you will have the button range versus UTG for 30BB deep.

Double-clicking on a player brings up a push range. As before, clicking on another player will then show their call range against an opponent's stack.

Example: A first left click on HJ, a second left click on HJ and then a third left click on 12BB, will give the push range of High Jack 12 BB deep. A fourth click on the BB will add the call range of the big blind to the High Jack's stack

At any time, a right click on the table will start over

The rangor ranges

In this situation, we have defined a spot, on the right of the screen, of Raise from the Cut-off and call from the button at a depth of 25 blinds. Rangor then gives us two charts, the OC opening range and the button call range. On the left hand side of the screen the second range is shown, colour coded to show the different possible actions and their frequency

Edit mode

To create your own ranges, go to the "Edit" mode. This time, you can create your own ranges in a specific spot, with the possibility of saving them and modifying them as you wish

As in the View tab, you must first choose the spot to study, indicating the table format, then clicking on the different players to describe the hand action, following the same formula as in the View tab.

Once the spot has been chosen, it is time to build its range. Each time, you will have to choose the decision (call, raise, 3-bet, 4-bet, all-in, call vs all-in...) and the frequency associated to this decision (the frequency of call, raise, 3-bet...).

To fill in your range, just click on the hands you want to include. Several shortcuts to go faster: A double click in the bottom right corner selects all pairs. A double click in the upper right corner selects all hands with an ace. A double left click on a hand will include all hands appearing in the square, where this box represents the bottom right corner of that square.

Finally rangor offers rows that have been simplified using a new algorithm in 25,50,75,100 frequency. A tool that allows you to learn and refine your skills with greater ease while maintaining excellent accuracy

Create a range with Rangor

Creating a range based on a given spot: You can fill in your table by colour-coding the different possible actions and their frequency for each hand

One of the advantages of the software is that you can configure and adapt it to your tastes and needs. The colour codes, percentage options, and functionality of each click can be changed or removed in the settings tab


Rangor also offers a training section, developed in the form of quizzes, where you can perfect your range science. Several exercises are available.

  • The Range Finder, where you have to select the right range in a given spot
  • The Action Finder, where you are asked to identify the correct frequencies of different actions in a given spot
  • The Global Frequency, the same exercise as the Action Finder, but with more precision in defining frequencies.
  • The Draw My Range, where you have to draw the range to play in a given spot

In each of the exercises, it is possible to parameterize with great finesse the type of spots on which you wish to help each other, thanks to the multiple filters. The number of players, the depth or the difficulty of the spots can be specified, to adapt the exercise to your needs

A pleasant and intuitive design

Rangor software design

Rangor has spared no effort with regard to the aesthetics of the software. The various screens are smooth and easy to read, and the animations are light, designed to provide an efficient experience without unnecessary detail

While a quick look at the instructions for the various View and Edit modes is highly recommended, the software is very intuitive to use. Obviously, a knowledge of poker terms and abbreviations will be necessary to decipher the language and understand Rangor's objectives. A regular player, interested in the concept of range and wishing to progress, will be able to find his way around the interfaces and take advantage of the software's full potential
