Range vs range equity
Set your built range against an opponent range and an optional board, then run a fast Monte Carlo simulation to get each side's win, tie and equity share. The pot is split correctly among all winners.
Build a range on the grid above and it shows up here.
Click or drag to set the opponent range.
Board (optional)
Leave the board empty for preflop equity, or add a flop, turn and river to narrow it down.
How your range hits the board
Once a flop is set, the builder breaks your whole range down into made hands, draws and air. It is the kind of board-texture read serious players open Flopzilla for, only it runs right here.
Add at least a flop above to see how your range connects with it.
The poker range builder, explained
A range builder turns the vague advice "think in ranges" into something you can see and measure. As of 2026 this one does more than draw a chart: paint a range on the 13×13 matrix, copy it as solver notation, pit it against an opponent range for live equity, and watch the whole range split into made hands and draws on any flop. Here is what each piece does and how to get the most out of it.
What this tool is
At its core it is the standard 13×13 grid of all 169 starting hands. Pairs run down the diagonal, suited hands sit above it, offsuit hands below. You click or drag to select hands, and the builder keeps a running count of combos and the percentage of all hands your selection covers. That part you will recognize from any range chart.
The difference is everything around the grid. You can color hands by action, export the range in the exact text format solvers read, paste a range back in from somewhere else, run range-vs-range equity with an optional board, and break the range down by how it connects with a flop. Most free tools stop at the grid. This one carries the range all the way to a decision.
The thing that finally made ranges click for me was building my UTG open and my button open, then putting them side by side. Seeing how much wider the button plays, in combos rather than as a vague feeling, changed how I thought about position for good.
Why a range builder matters
Beginners ask what one hand their opponent holds. Stronger players ask what their whole range looks like and decide against all of it at once. A builder trains that habit, and it gives you a place to store and compare the ranges you actually play.
You stop guessing single hands
When you can see an opponent's range as a block of combos, you stop trying to read a single holding and start playing the distribution. That is the single biggest jump from a recreational player to a thinking one, and the grid makes the distribution concrete.
Position becomes a number
From early position you open something like 10 to 15 percent of hands. From the button it can be 40 to 50 percent or more. Build a range for each seat, read the combo count off the grid, and that abstract idea turns into figures you can actually compare and remember.
You build a repeatable plan
With a saved chart you open hands to a plan instead of to your mood. That alone removes a pile of spur-of-the-moment mistakes, and when you review a session later you can rebuild an opponent's range and find where you drifted outside your own.
How the 13×13 matrix works
The grid holds exactly 169 unique starting hands. Pocket pairs sit on the diagonal from AA in the top-left to 22 in the bottom-right. Everything above the diagonal is suited and carries an s, such as AKs or T9s. Everything below is offsuit and carries an o. Premium hands cluster in the top-left, so a tight range looks like a small block in that corner and a loose one spreads toward the bottom-right.
Each cell is worth a different number of combos, and that matters more than it looks. A pocket pair is 6 combos, a suited hand only 4, and an offsuit hand 12. So the builder works your percentage from the 1326 total starting combos, not from the number of cells you colored. Highlight every pocket pair and you have a smaller slice than it appears, while a handful of offsuit hands inflates a range fast. The combo count keeps you honest.
How to build a range on toolsgambling.com
The whole tool runs in your browser on toolsgambling.com, free and with no login. Nothing leaves your device. Here is the workflow from an empty grid to a saved, analyzed range.
- 01
Pick an action, then paint
Choose raise, call, fold, 3-bet or all-in, then click or drag across the grid. Every cell you touch takes the current action's color, so you can map a raising block and a calling block inside one range. On a phone, tap and drag works the same way.
- 02
Or load a preset and adjust
Short on time? Load a position preset like UTG, CO, BTN, SB, a blind defense range or a short-stack push range. These are solid GTO approximations meant as a starting point, not a rulebook, so tweak them to fit your table.
- 03
Use the top percent slider
Drag the slider to fill the grid with the strongest X percent of hands, ranked by the Chen formula. It is a quick way to sketch a linear opening range, and you can fine-tune from there by hand.
- 04
Read the analysis
Below the grid the builder splits your range into pairs, suited and offsuit hands, and shows how many hands sit under each action. It is an easy way to spot a leak, like too many weak offsuit hands bleeding into an opening range.
- 05
Save, share or export
Name a range and save it to your browser, copy a share link that reopens the exact scenario, or copy the range as solver notation to paste into Equilab, Flopzilla, PioSolver or GTO Wizard.
Reading board texture with your range
Set a flop and the builder runs every combo in your range against it, then sorts the results into made hands, draws and air. You see the share of your range that flopped a set, two pair, top pair or an overpair, the share with a flush draw or a straight draw, and the share that completely missed. Cards already on the board are removed from the range first, which is the correct way to count.
This is the read serious players open Flopzilla or HoldEq for: how often does my opening range actually connect with this board, and how strong are the parts that do? When your whole range flops a strong hand or a good draw often, a continuation bet makes sense. When it mostly misses, slowing down is usually the better line. Doing this for a few common flops trains the instinct fast.
Range vs range equity
Once you have a range and an opponent range, the equity panel runs a Monte Carlo simulation and reports each side's win, tie and total equity share. You can leave the board empty for a preflop number or add a flop, turn and river to see how the matchup shifts street by street. The pot is split evenly among all winners, which is the only correct way to count ties, so three-way splits read as a true even share rather than a rounding mess.
A quick example: a tight 3-bet range against a wider calling range is usually a small favorite preflop, but a low, connected flop can flip that fast when the caller's range hits more two pairs and straights. Watching that swing on real boards is far more instructive than memorizing a single preflop percentage, and it pairs naturally with the texture breakdown above.
Common range mistakes
Counting cells instead of combos
Adding offsuit hands widens a range three times faster than adding suited hands of the same ranks. If you judge a range by how many cells are lit rather than by the combo count, you will run far looser than you think. Watch the percentage, not the picture.
Treating presets as gospel
The presets are sane defaults, not solved answers. True ranges depend on format, stack depth, rake and the players in the seats. Use a preset as a baseline, then deviate to exploit the table in front of you.
Ignoring card removal
When you hold an ace, the chance an opponent also holds one drops. The equity engine and the texture breakdown both account for this by removing known cards. If you reason about ranges in your head, remember that blockers quietly reshape what is left.
Building a range and never reviewing it
A chart you set once and forget stops matching the games you play. Save your ranges, revisit them after losing sessions, and adjust. The point is a living plan, not a museum piece.
Range terminology
A few core ideas make the grid and the analysis easier to read. Each one shapes how you build and judge a range.
Core concepts
- The full set of hands you or an opponent play in a given spot. Thinking in ranges instead of single hands is the foundation of solid poker.
- The specific card combinations a hand notation covers: 6 for a pocket pair, 4 for a suited hand, 12 for an offsuit hand. There are 1326 starting combos in all, and your range percentage comes from that total.
- Suited (s) means both cards share a suit, such as AKs, with a shot at a flush. Offsuit (o) means different suits, such as AKo. Suited hands are a touch stronger preflop because of that flush potential.
- The text shorthand solvers use, like JJ+, ATs+, KQo. A plus means and up, so JJ+ is JJ, QQ, KK and AA. This builder reads it and writes it, so ranges move cleanly between tools.
- How the community cards interact with a range: dry boards favor the preflop aggressor, wet and connected boards help the caller's range hit more strong hands and draws.
- Holding a card lowers the chance anyone else holds it. Removal trims an opponent's possible combos and quietly shifts equity, which the simulation here accounts for automatically.

Keep in mind
The presets and the Chen-formula top percent are reference points, not the last word. Optimal ranges depend on format, stack depth, rake and your opponents. Treat the builder as a thinking tool and a template, not a solved answer for every hand.
