Stop Guessing: The Free Preflop Pass from PLO Mastermind is Here
If you are still “feeling” your way through opening ranges in 2026, you are torching money.
In Omaha Poker, the edge isn’t just found on the river; it starts the moment you decide to put chips in the pot. For years, the barrier to entry for solving this was cost. PLO Solvers were expensive, and subscriptions added up.
That barrier just vanished. The Pot Limit Omaha training site PLO Mastermind has released the Preflop Pass. It is a free PLO solver that gives you access to professional GTO ranges without any cost.
Here is why this update is a game-changer for micro and low-stakes grinders.
What is the Preflop Pass?
The Preflop Pass is essentially a “lite” version of the industry-leading PLO Trainer. While the full paid membership unlocks deep postflop simulations and complex node-locking, this free tier focuses exclusively on the most critical street in the game: Preflop.
It gives you unlimited, browser-based access to solved 6-Max ranges for both 4-Card PLO and 5-Card PLO.
If you have been looking for a PLO Trainer Preflop Pass that doesn’t require a credit card or a monthly commitment, this is it.
Why You Need This Tool
Most players think they lose money because of “bad beats” or “coolers.” The reality? They lose because they enter pots they had no business being in.
With the Preflop Pass, you stop guessing. You get access to:
- 4-Card PLO Ranges: 100bb deep solutions based on standard rake structures.
- 5-Card PLO Ranges: The increasingly popular variant is fully supported.
- Instant Feedback: The “Train” mode lets you play through hands and get instant corrections on your EV loss.
By using the PLO Trainer Preflop Pass, you build a solid baseline strategy that protects you from the rake traps common at lower stakes.
Browser-Based & Risk-Free
One of the biggest advantages of the PLO solver from PLO Mastermind is accessibility. There is no heavy software to download and no complex installation process.
The PLO Trainer Preflop Pass runs directly in your browser. This means you can study ranges on your desktop during a session review or drill a few hands on your phone while waiting for a table.
It is designed to be frictionless. You sign up, you log in, and you start training.
Is It Really Free?
Yes. Unlike “free trials” that ask for your payment details hoping you forget to cancel, the Preflop Pass is permanently free. PLO Mastermind has structured this as an entry point for players who are serious about improvement but aren’t ready for the full suite of tools yet.
If you are grinding PLO10, PLO25, or even PLO50, the value here is immense. You get the exact same preflop solutions used by high-stakes pros, simply limited to the 100bb stack depth, which is exactly what you need for 90% of your games.
Free Pass vs. Paid Trainer: What Are You Missing?
The Free Preflop Pass is an incredible tool for building a baseline, but it is limited by design. It solves the “100bb Preflop” game perfectly, but PLO is rarely played at exactly 100bb deep with zero postflop decisions.
If you are a serious grinder, you eventually need to study Postflop, Deep Stacks, and Tournament ICM. That is where the paid PLO Trainer membership comes in.
Here is the direct breakdown of the differences:
PLO Mastermind: Free vs. Paid Comparison
| Feature | Free Preflop Pass | Paid PLO Trainer |
|---|---|---|
| Price | $0 / Forever | $179/mo (Standard) |
| Preflop Ranges | 100bb Only | 20bb, 40bb, 50bb, 75bb, 100bb + Deep Stacks |
| Game Types | 6-Max Cash (4 & 5-Card) | Cash, MTTs, Heads-Up, Live 8-Max, ICM |
| Postflop Sims | ❌ None | ✅ Yes (Flop, Turn, River) |
| Training Mode | Preflop “Single Node” Only | Full Postflop, Random Board, Multi-Street |
| Rake Structures | Fixed (Low Stakes 5%) | Multiple (Low, Mid, High & Site Specific) |
| Strategy Content | 6 Intro Videos | 500+ Videos + Weekly New Content |
| Advanced Tools | Basic EV Feedback | Range Matrix, Aggregated Reports, Node-Locking |
When Should You Upgrade?
The Free Preflop Pass is sufficient if you are just learning the game or transitioning from No Limit Hold’em. Mastering 100bb preflop ranges is the “80/20” of PLO. It fixes 80% of your leaks with 20% of the effort.
However, you should upgrade to the full PLO Trainer if:
- You play MTTs: The free version does not cover tournament stack sizes (20bb-50bb) or ICM pressure.
- You play Deep: If you regularly play 200bb+ deep, using 100bb ranges will cause you to overvalue aces and undervalue rundown connectivity.
- You need Postflop Drills: The money in PLO is made by navigating complex turn and river runouts. The paid version allows you to drill “Random Boards” to sharpen your intuition for these high-variance spots.
Conclusion
If you want to stop bleeding chips and start building a professional process, grabbing the Preflop Pass is a no-brainer.
It’s rare to find a tool this powerful for $0. The PLO Trainer Preflop Pass removes the excuses. You no longer have to guess which rundown to open from the Cutoff or how to defend your Big Blind against a 3-bet.
Head over to PLO Mastermind, grab your pass, and start tightening up your game today.
