Main Functions

All Flopzilla tools are accessible in one window. Here’s an overview:

Hand Matrix

A 13×13 grid representing all possible hole cards. Suited hands are in the upper triangle, off‑suit hands in the lower triangle, and pocket pairs along the diagonal. You can select a hand and see its preflop or flop equity.

Community Cards

This section also displays 52 cards by suit in four columns. After selecting a hand or range, the first three cards you mark in the board section become the flop, the fourth the turn, and the fifth the river. Simply enter two hole cards and the board cards to see their equity.

Statistics

One of Flopzilla’s key sections. It shows how often your cards will win in percentage terms. Suppose you think an opponent with a backdoor range won’t always continuation‑bet with a made flush. Click next to the flush row and use the scroll wheel to set the desired frequency. If the opponent won’t continuation bet, simply click the blue filter.

Dead Cards

Here you can set your own hole cards or cards that are definitely not coming postflop. This section helps refine preflop strategy calculations.

Flopzilla Pro Differences

This is the new and improved version of the popular equity calculator. At first glance the programs look similar, but Flopzilla Pro includes many new features:

  • Multi‑pot analysis – the previous version couldn’t handle multiple ranges simultaneously.
  • Range analysis with a pie chart (located on the right side of the window).
  • Resizable windows, convenient for reviews and copying ranges.
  • New option to account for backdoor flush draws with one card.
  • Range enhancements: select suits, color‑code hand groups, equity graph and equity matrix.
  • Workspace scaling.
  • Even faster calculations.
  • Integration with GTO+ software.
  • More detailed preflop stats.
  • New “Flop Breakdown Tool” providing precise information on each possible flop.

Overall, Flopzilla Pro similarly helps players think in ranges and make more informed postflop decisions. And you don’t need to buy Flopzilla Pro separately – it’s available free to all owners of a license for the previous Flopzilla.

How to Purchase

The current price for Flopzilla is $25. You can download the program from the official website, where a 7‑day trial version is also available. Beginners are advised to install the program first, even just to test its functionality. This allows you to appreciate the depth of analysis it provides, helping you better understand the game from preflop onward. This level of analysis is not common knowledge among all professionals, and using Flopzilla can significantly improve your play.

Note: To purchase the software, you need a unique Hardware ID. To obtain it, download the corresponding application, run it, and select the “Register” option from the menu.

To use the program on two computers, or after reinstalling your operating system or changing computers, follow the link and enter the new Hardware ID along with the email address used for the purchase. A new activation key will be sent to that email address.

To activate Flopzilla Pro if you already own a Flopzilla license, go to the link and enter the Hardware ID from Flopzilla Pro and the email address used for the original purchase. An activation key will then be sent to you.

Overall Assessment of Flopzilla

A brief list of tips for working with Flopzilla:

  • To save ranges, open the “Save/Load” section and select “Export predefined ranges”. A text will appear; copy it and paste it into the “Import predefined ranges” window (on another device).
  • To import the software to another device, contact support at contact@flopzilla.com.
  • Using Flopzilla while the PokerStars client is open is strictly prohibited.

Overall, Flopzilla is a unique poker calculator that lets you evaluate hand strength.

To see if Flopzilla suits you, a free 7‑day trial is available (you can only view cards up to the flop). The paid version costs $25 and can be used on two devices. Give it a try!

Why Use Flopzilla Together with HisHands

Flopzilla is great for analyzing hand strength and opponent ranges on different streets. But it becomes even more powerful when combined with HisHands: this service collects all your hands from online rooms and lets you quickly import them into Flopzilla for detailed review. You can see where you misjudged equity, where you played too passively or too aggressively, and then adjust your strategy and style accordingly.

Integrating Flopzilla with HisHands mining is possible, though it requires a few extra steps since there’s no direct automatic integration. However, you can use them together effectively for deep poker hand analysis.

  3. Import into Flopzilla: Open Flopzilla and manually enter the hand information from the text file. This includes hole cards, board cards, and actions on each street (preflop, flop, turn, river).
  4. Analyze with Flopzilla: After entering the data, Flopzilla provides detailed equity analysis for each hand, showing how often your hand or range hits various board combinations. You can visualize the probability of making top pair, flush draws, straight draws, and more.
