Flopzilla or GrindLab: how will you study your ranges?
A difficult hand becomes clearer when you can change the ranges and observe what happens. Flopzilla and GrindLab enable that exploration in different environments: Windows analysis software and a lab accessible in your browser.
Start with a range or start with a hand
Flopzilla
Select a preflop range, add a flop and examine the breakdown: pairs, draws, strong hands and hands that barely connect. Filters help refine the view and follow the hand groups that interest you.
Particularly useful for connecting a preflop hand grid with situations encountered after the flop.

| Your need | Flopzilla | GrindLab |
|---|---|---|
| Environment | Software installed on Windows. | Analysis tools available in the browser. |
| Read a range | Breakdowns by hand category, combinations and filters. | Build and adjust ranges to explore a situation. |
| Compare equity | Heads-up and multiway calculations. | Range comparisons, including multiway pots. |
| Practical starting point | A range and board to study in detail. | A hand and the assumptions you want to test. |
| Move to GTO study | Connects with GTO+ to exchange ranges and the board. | Exploratory work that can be extended with a solver, depending on the question. |
Both tools can work with multiway pots. To choose between them, focus on how easily you can build the situation, adjust a range and read the result.
Try the same question in both tools
Review exercise · no prescribed frequency
You opened from the cutoff and the button called
Build the button’s calling range as you imagine it. The aim is to understand its composition on this flop before looking for a bet size.
- 01
Describe
Find the kings, middle pairs and unpaired hands. Note what surprises you.
- 02
Modify
Compare two assumptions: one contains more offsuit broadways, the other more suited connectors. Do not change the board at the same time.
- 03
Explain
Which categories gain or lose weight? How does your hand’s equity change against each range?
Keep the ranges identical in both tools to compare how comfortable the work feels. Click count matters less than being able to explain what you have learned.
Connect equity with the poker decision
Equity describes your share of the pot at showdown against the hands included in the analysis. To decide whether to bet or call, also understand the available actions, amounts and hands that continue. Good equity against the starting range does not by itself explain what happens against a raise.
After a bet
Ask which hands call, raise or fold. You can then study a more precise continuing range.
After a new card
Keep track of the hands retained on the previous street. The turn range follows from the flop action.

You enjoy examining combinations and textures
Flopzilla is particularly well suited to this study, with a GTO+ connection if you then want to work on a decision tree.

GrindLab fits easily into a session where you start with an uncertainty and work through several evolving assumptions.
You are new to range study
Begin with a simple situation and the available trial options. Learning to build a coherent range is already a valuable exercise.
