About PLO Spot
PLO Spot is a free, browser-based study suite for Pot-Limit Omaha. It brings GTO-based preflop ranges, an interactive decision trainer, and a fast equity calculator into one place — no account, no download, no cost.
What you can do here
PLO5 & PLO4 preflop ranges
Browse solver-derived opening, 3-bet, and defense ranges for 5-card and 4-card Omaha across every position. Hands are grouped by category so you can see why a holding belongs in a range, not just whether it does.
Interactive trainer
Pick a spot, get dealt real hands from that node, choose your action, and receive instant feedback graded against the solver. A dashboard tracks your accuracy, EV loss, and streaks so you can see where your preflop game leaks.
Equity calculator
Run hand-vs-hand and multiway equities for PLO4 and PLO5, with exact enumeration on small boards and Monte-Carlo estimation when the runout space is large. Add a board to see how equities shift street by street.
Who it's for
Anyone studying Pot-Limit Omaha — from players moving over from Hold'em who want to understand Omaha's wider, nuttier ranges, to experienced grinders drilling preflop spots until the right decision becomes automatic. PLO Spot is a strategy-study tool only; it does not offer real-money gambling.
How to get the most from it
- Start in the range browser to see the baseline strategy for a position.
- Read the preflop strategy guide to learn the principles behind the ranges.
- Switch to the trainer and drill that spot until your accuracy climbs.
- Check the dashboard to find the spots costing you the most EV, and repeat.
