Flopzilla: understand how a range really connects with the board

How many top pairs are there on this flop? Which draws remain on the turn? Flopzilla makes ranges tangible. Change a hand, its weight or a board card, then see what changes.

01

From “they often hit this flop” to reading the whole range

At the table, it is easy to think in individual hands: “they could have ace-king”, “perhaps they have a pair”. Flopzilla helps broaden that view. You examine a group of hands and see how the flop changes its composition.

See the hand categories

Top pairs, middle pairs, draws: the breakdown shows what makes up a range on a particular board.

Test your assumptions

Remove a hand category or change its frequency. You immediately see why a preflop assumption matters later in the analysis.

Compare equity

The calculator supports both heads-up and multiway pots, so you can study very different situations in the same environment.

This is particularly useful when you want to explain decisions in your own words. Instead of remembering only that a flop is “bet frequently”, identify the strong hands, medium-strength hands and draws that support the way you want to play it.

02

One range, two flops: try it yourself

Here is an original exercise to repeat away from the tables. Enter a deliberately small range: 77+, ATs+, KQs, AJo+, KQo, with every combination at the same frequency. It is designed to help you read the tool, rather than represent an optimal preflop range.

Flop A · Dry, ace-high

Find the aces and medium-strength hands

Which hands make top pair? Where do pairs such as QQ or JJ stand? Look at what happens to 77 too. Before reading the results, estimate the share of hands that connect well with this flop.

Flop B · Connected, two-tone

Look at draws and overlapping categories

Keep the same range. Compare pairs, sets and draws. KQ now has an open-ended straight draw; some combinations also have a flush draw. One hand can belong to several categories.

The question to take away

“Which parts of my range change most from one flop to the other?” Answer first with hands and hand categories, then with percentages. You build an intuition that the numbers help refine.

To extend the exercise, add a turn. On the second flop, compare a low non-spade with the queen of spades, for example. Separate hands that were already strong from those that improve: this is the foundation of reading ranges across streets.

03

Combos make blockers much clearer

“AK” is not just one possible hand. Before any board cards are known, ace-king has sixteen combinations: four suited and twelve offsuit. On A♠ 7♦ 2♣, the ace of spades is already on the flop, leaving only twelve combinations.

16 → 12

AK

An ace on the board removes four combinations.

6 → 3

77

The seven on the board reduces the pocket-pair combinations.

6 → 6

QQ

No queen is visible, so the count stays the same.

Illustrative counts on A♠ 7♦ 2♣, with no other known cards and every original combination included at 100%.

Count again after adding your own hand. This is an excellent way to understand blockers: instead of simply saying “I have an ace”, you see exactly which opposing combinations are no longer possible.

04

Use equity to improve your reasoning

Equity is the average share of the pot belonging to a hand or range if the studied scenario reaches showdown. When considering a bet or call, you also need to account for the price, position and future actions.

  1. 01

    Reconstruct the spot

    Record the positions, effective stack and actions so far. Your range must fit that sequence, rather than just the two cards revealed at the end.

  2. 02

    Set out two assumptions

    Build an initial opposing range, then a plausible variation: more draws, fewer weak hands or a tighter selection of value hands.

  3. 03

    Compare what moves the result

    Find the hand categories responsible for the change. This teaches you which information would be most useful for refining your read.

  4. 04

    Write a poker conclusion

    For example: “My bluff-catcher does well against missed draws, but much less well against a range made up almost entirely of value hands.” That sentence is more useful than memorising a percentage on its own.

FlopzillaPro and Flopzilla v1 included

The perpetual licence includes updates and covers two computers you own. Taxes may apply depending on your country. The publisher currently recommends FlopzillaPro, available on Windows.

View the Flopzilla licence

For a player willing to spend time reading ranges, the price compares very favourably with the study possibilities. The software works equally well for short ten-minute exercises and more detailed reviews.

Still getting familiar with these concepts? Start with this guide’s examples and the publisher’s videos to see whether this way of learning suits you.

06

Where does it fit alongside your other tools?

Flopzilla is particularly enjoyable for exploring an assumption while keeping the underlying hands in view. You can retain that approach while using a solver to study strategy or another environment to vary your exercises.

Frequently asked questions about Flopzilla

Is Flopzilla a solver?

Flopzilla analyses range composition and equity. To study a betting strategy with a solver, you can continue in GTO+, which connects to FlopzillaPro. The two approaches work very well together.

Can Flopzilla analyse multiway pots?

Yes. The current version calculates equity in heads-up and multiway pots with up to 14 players. Flopzilla is therefore useful beyond analysing a single range or pots involving just two players.

Which version should I install first?

The publisher recommends FlopzillaPro. The older Flopzilla v1 remains available, particularly for following training materials that use it. Both versions are included in the licence.

Is Flopzilla suitable for beginners?

Yes, once you understand ranges, draws and equity. Start with a small range and a single flop. If those basics are still unclear, learning them through free resources first will help you get much more from the software later.

Is Flopzilla worth the price?

Yes, for players who enjoy understanding hands by manipulating ranges. Its one-time price makes it easy to keep in a study routine. The value is clearest through repeated exercises: predict how a range connects, check, then explain the differences.
