The Best PLO Solvers in 2026: The Ultimate Guide to Web-Based GTO Tools

Stop guessing. Start knowing.

If you are still trying to “feel” your way through Pot Limit Omaha, you are burning money. The days of relying on intuition or outdated heuristic rules are over. The modern game is driven by precision, and the gap between breaking even and crushing the game is defined by one thing: how well you understand Game Theory Optimal (GTO) strategy.

For years, studying GTO meant buying a $3,000 supercomputer, installing complex desktop software, and waiting 14 hours for a single simulation to run. That barrier to entry kept the secrets of the pros locked away.

That era is dead.

Today, the best PLO solvers are entirely web-based. They live in the cloud, run on your laptop (or even your phone), and deliver answers instantly. But with accessibility comes a new problem: Choice.

We have vetted the four biggest heavyweights in the industry: PLO Trainer (from PLO Mastermind), PLO Genius, FlopHero, and Run It Once Vision. We tested them on features, speed, price, and accuracy to help you decide which tool deserves your time and money.

Here is your no-nonsense guide to the best GTO tools on the market.

Why You Need a Web-Based PLO Solver

Before we tear into the reviews, let’s be clear about why you need one of these tools. A PLO solver is not just a calculator; it is a map.

In No-Limit Hold’em, you can often get away with basic charts. In PLO, the equities run so close that a single mistake, like c-betting a double-suited rundown on the wrong texture, can torch your win rate.

Traditional desktop PLO GTO solvers were powerful but brutal to use. You had to build the game tree manually (which takes hours) and run the sim locally (which takes massive RAM). The new generation of web-based tools is actually “Library Solvers” or “Trainers.” The companies have already run the millions of hours of calculations on their servers.

When you use a tool like PLOGenius or FlopHero, you aren’t “solving” the hand from scratch; you are accessing a massive database of pre-solved solutions. This means:

1. Zero Wait Time: You get the answer instantly.
2. No Hardware Requirements: If your device can load a webpage, it can run the the PLO GTO solver.
3. Visualization: These tools don’t just give you a grid of numbers; they use heatmaps and “Strength Buckets” to help you actually understand why a play is correct.

If you want to stop bleeding EV (Expected Value) and start printing money, you need one of the following four tools in your arsenal.

1. PLO Mastermind Trainer: The Educational Ecosystem

The PLO trainer is arguably the most recognized PLO solver in the space, largely because it sits inside the massive PLO Mastermind educational ecosystem. If you are looking for a tool that holds your hand and guides you through the learning process, this is likely your starting point.

The Complete Ecosystem

Unlike standalone tools, the PLO Trainer is integrated with a training site that hosts over 1,100 strategy videos. This is a massive advantage for players who don’t just want to see what the GTO solver does, but want a coach to explain why it does it. When you hit a wall in the PLO solver, there is usually a video or a quiz (they have 350+ of them) to back up the theory.

Key Features and Usability

The interface is browser-based and clean. It splits the game into clear preflop and postflop modules.

• 4-Card & 5-Card Support: The trainer supports both major variants. The 4-Card library is massive, with over 1 million solutions. The 5-Card PLO library is growing rapidly, which is essential as the action shifts to PLO5.
• Strength Buckets: This is a standout feature for learning. Instead of just seeing that you should bet a specific hand, the system groups hands into “buckets” (e.g., Top Pair + Nut Flush Draw). This helps you simplify complex GTO output into human-readable rules.
• Preflop Pass: This is the killer feature for beginners. PLO Mastermind allows you to access their preflop charts for free. You can fix the most expensive street in PLO (preflop) without spending a dime.

Who is it for?

The PLO trainer from PLO Mastermind is best for the “Student.” If you want a structured path, like videos, quizzes, and a trainer all in one place, this is the ecosystem for you. It’s less of a quick-fix tool and more of a university for poker players.

2. PLO Genius: The Cloud-Based Visualizer

PLO Genius has made waves by focusing entirely on speed and visualization. It positions itself as a “Cloud-Based Powerhouse,” and in our testing, it lives up to the hype. This PLO solver is designed to look good and work fast, stripping away the clunky interfaces of older software.

Intuitive Visualization

The hardest part of using a PLO solver is interpreting the data. PLOGenius solves this with a unique visualization system that categorizes hands logically. It breaks ranges down into:

• Rainbow combinations
• Single-suited hands
• Double-suited hands
• Paired/Unpaired combinations

This sounds simple, but when you are trying to visualize a 15% opening range, seeing it color-coded by suitedness makes the patterns pop instantly. It bridges the gap between theoretical understanding and practical application better than most.

All-in-or-Fold (AoF) Dominance

This is where PLO Genius creates a league of its own. It is currently the market leader for All-in-or-Fold solutions. It offers complete strategic solutions for all 1,755 isomorphic flops in AoF. If you play this high-variance format on sites like GGPoker, PLO Genius is effectively mandatory. No other tool covers this niche with the same depth.

No Setup Required

True to the modern standard, there is zero setup. It runs on a 10 Mbps connection and a browser. Whether you are on a high-end desktop or a standard laptop, the performance is identical.

Who is it for?

PLO Genius is for the “Visual Learner” and the niche specialist. If you struggle to read raw data grids, their color-coded categories will unlock the game for you. Additionally, if you grind AoF in addition to PLO4 and PLO5, this is your only real option.

3. FlopHero: The Automated Leak Detector

The PLO solver FlopHero is different. While the other tools on this list are primarily a “PLO Trainer” (where you simulate hands), FlopHero is an “Analyzer.” It connects directly to your hand history to find your actual mistakes.

Automated Hand Analysis

This is the feature that changes everything. FlopHero imports your real played hands and runs every single decision through its internal GTO library. A few seconds later, it spits out a ranked list of your biggest errors, sorted by EV Loss.

Instead of guessing, “Did I play that 3-bet pot correctly?”, FlopHero tells you: “You lost 4.2 BB in EV by checking this turn.” It removes the friction of manual filtering. You don’t have to build trees or select spots; the software tells you what to study.

Instant Full-Street Solving

Many PLO solvers take shortcuts with “representative” boards. FlopHero offers full-street coverage, Flop, Turn, and River, instantly. It achieves this by combining a massive library of solved flops/turns with a real-time river GTO solver. This ensures that when you review a hand, you are looking at the exact math for your specific situation, not an approximation.

The Leak Trainer

Once FlopHero identifies that you suck at defending the Big Blind vs. a C-bet, it doesn’t just shame you, it builds a drill for you. The Integrated Leak Trainer creates personalized training sessions based on your actual database errors. This creates a powerful feedback loop: Play -> Analyze -> Drill -> Improve.

Who is it for?

FlopHero is for the “Efficiency Freak” and the Micro/Mid-stakes grinder. If you hate the idea of manually setting up training drills and just want to know exactly where you are losing money, this is the tool for you.

4. Run It Once Vision: The Pro’s Drill Station

Backed by the G.O.A.T. Phil Galfond and the team at Run It Once, Vision (often called Run It Once Vision or just Vision) is built for one thing: Reps. It treats poker study like athletic training. You need to put in the reps to build muscle memory.

Streak Mode

This is the standout feature of Vision Run It Once. Streak Mode gamifies your study. It throws spot after spot at you, Preflop, Flop, Turn, River, and tracks your accuracy streaks. It forces you to make decisions under pressure, simulating the feel of a real session. This is incredibly effective for warm-ups. Spending 15 minutes in Streak Mode before a session ensures your brain is calibrated to GTO frequencies before you post your first blind.

High-Fidelity Solutions

The solutions in Run It Once Vision are generated using MonkerSolver (the gold standard for raw solving) and then curated for the web interface. This means you are training against high-trust data. The tool covers 4-Card and 5-Card PLO extensively, with support for 6-max and Heads-Up.

Mobile Friendly

While all these tools are web-based, Vision Run It Once is particularly well-optimized for mobile. This PLO solver allows you to drill hands while commuting or sitting on the couch, making it easier to fit study time into a busy schedule.

Who is it for?

Vision is for the “Athlete.” If you believe that volume cures everything and you want to drill thousands of hands to internalize patterns, Vision is the best gym in town. It is less about “explaining” the theory (like Mastermind) and more about “practicing” the execution.

Comparison: Which PLO Solver Should You Choose?

Comparing these PLO solvers can be tricky because pricing models and feature sets vary. We have broken down the key specs to help you compare them head-to-head.

Verdict: The Right Tool for Your Game

There is no single “perfect” PLO solver, but there is definitely a right tool for you depending on where you are in your poker journey.

• Choose PLO Trainer if you are a beginner to intermediate player who wants a full “school” experience. If you need videos to explain the concepts behind the PLO solver outputs, the ecosystem here is unbeatable. The Free Preflop Pass is also a no-brainer starting point with 0% risk.
• Choose PLO Genius if you are a visual learner or an All-in-or-Fold player. If standard data grids give you a headache, the color-coded hand categories in PLOGenius will change how you view the game. It is also the only viable option for serious AoF study.
• Choose FlopHero if you are efficient and want to fix leaks fast. If you don’t have time to browse random simulations and just want to know “Where did I lose money yesterday?”, FlopHero is the most practical tool on the list. It tells you exactly what to fix.
• Choose Run It Once Vision if you are a grinder who learns by doing. If you want to put in 500 reps before breakfast and build unshakeable intuition, the Streak Mode in Vision Run It Once is the industry standard for drilling.
