What a poker solver is
A solver is a calculator for poker strategy, and it is the most misunderstood purchase in the game. This page explains what it computes, what it refuses to tell you, and how to work out whether you are the player who should own one.
A calculator, not an oracle
You describe a situation completely: the stacks, the board, the bet sizes allowed, and the full range of hands each player could be holding. The solver then plays that situation against itself, over and over, adjusting until neither side can improve by changing anything. What comes out is a table of frequencies. With this hand, bet this often. With that one, check. The underlying idea is game theory optimal play, which is a strategy designed to be unexploitable rather than one designed to beat the person opposite you.
Three things follow from that, and all three surprise people. The answer is only as good as the situation you described, so a sloppy setup gives a confident wrong answer. The output is a distribution rather than an instruction, so there is no line to copy. And because the whole model assumes an opponent who is also playing perfectly, it will not tell you how to punish the player at your table who folds too much. That last part is what most of your profit actually comes from at low and mid stakes.
It is worth separating this from the tools it gets confused with. A pot odds calculator answers one arithmetic question in a second and costs nothing. An equity calculator tells you how often one hand beats another by the river. Neither is a solver, and between them they answer most of the questions people believe they need a solver for.
the decision
When you need one, and when you do not.
buy one when
You cannot answer a frequency question
Not "was that call bad" but "how often should I be continuing here at all". If you can phrase the question in terms of how often, and you genuinely do not know, that is a solver question and nothing else on the market answers it.
buy one when
You have already fixed the obvious things
A solver is the tool after the basics, not instead of them. If your last three losing sessions came from spots you can already name, that is cheaper work and it does not need software.
buy one when
You will actually put the hours in
Reading solver output is a skill of its own, and the first few weeks feel like learning a spreadsheet. People who enjoy that get a lot from it. People who bought it to feel serious open it twice.
skip it when
You are playing the smallest stakes
Opponents at the bottom of the ladder deviate so far from any equilibrium that the exploitable adjustment beats the balanced one, and you can find those adjustments by watching what people do rather than by buying a licence.
skip it when
You have never reviewed your own hands
A solver has never seen you play. It answers the question you ask it, which means you have to already know which spot is costing you. Working that out from your own history is the step before this one, not after it.
skip it when
You want something to consult while playing
That is not what this software is for and it is prohibited everywhere. Solvers are study tools, used away from the table, on hands that are already over.
Trying one before you buy
You do not have to spend anything to discover whether solver work suits you. TexasSolver is open source under the AGPL v3 licence and free for personal use, with versions for Windows, macOS and Linux. If you would rather have a paid product, GTO+ is sold as a one time registration fee that includes future updates. Both were read from the vendors themselves on 30 August 2026, at github.com/bupticybee/TexasSolver and gtoplus.com/purchase.
Beyond those two, the licence models diverge sharply between a one time purchase and a monthly subscription to a precomputed library, and that is the choice worth thinking about. The solver comparison sets out each product with the vendor page it came from rather than repeating it here. Software moves, these pages do not update themselves, and the method page explains why every claim here carries a date.
What to do instead, or first
A large share of what people buy a solver to look up is preflop, and preflop has been solved into charts that anybody can read. The preflop charts on this site cover opening, calling and three betting by position, and they cost nothing. Working from those until they are automatic is a better first month than any licence.
The other half of the problem is that a solver cannot see you. It has no idea which spots you keep getting wrong, so you have to bring it the question. That is the gap the leak finder works in: it reads hands you already played and names the recurring decision that costs you most. Plenty of serious players run both, and in that order, because a solver is far more useful once you know what to ask it.
One thing neither of them will do is help you mid hand. Software that advises during play is real time assistance, rooms detect it and close accounts over it, and no amount of study value makes that a reasonable risk.
questions
Fair questions.
What is a poker solver? +
A program that takes one clearly defined situation, including stack sizes, bet sizes and the ranges of hands each player can hold, and computes a strategy that an opponent cannot exploit. It gives you frequencies, such as bet this often with this part of your range, rather than a decision for the hand in front of you.
Is using a poker solver allowed? +
Away from the table, yes. Every major poker room permits studying with software between sessions. What they prohibit is consulting anything during a hand you are playing, which is a separate category called real time assistance and gets accounts closed.
What is the difference between a solver and a poker calculator? +
A calculator answers one arithmetic question, such as what price you are getting on a call or how often a draw completes. A solver answers a strategic one, across an entire range of hands and every following street. The calculator takes a second and is free. The solver takes a machine, a defined tree and patience.
Do I need an expensive computer to run one? +
It depends entirely on what you ask it. A narrow spot with few bet sizes finishes quickly on ordinary hardware, and a deep tree with many sizes on every street can occupy a strong machine for a long time and use a great deal of memory. That trade off, rather than the licence, is what shapes how people study with solvers.
Is a solver the same thing as a HUD or a tracker? +
No. A tracker stores hands and shows statistics about opponents, in some cases on screen while you play. A solver stores nothing about anybody and knows nothing about your opponents. They are different products solving different problems, and rooms treat them very differently.
Do solvers exist for Omaha and for tournaments? +
Yes, though the situation is harder in both cases. Omaha has vastly more starting combinations, and tournament play needs the changing value of chips folded into the calculation rather than plain money. Check what a specific product supports before you assume your format is covered.
Will a solver make me win? +
It will make you better informed, and only if you do the work of turning the output into things you can remember at the table. Nobody plays a solver strategy in real time. What good players extract is a handful of rules that survive the walk from the desk to the table.
