PLO4 · PLO5 · PLO6 · NL Hold'em — up to 6 players, any street. Powered by a dedicated C backend for fast, accurate equity.
This is a free, browser-based equity calculator for Pot Limit Omaha 4,5,6 and No Limit Hold'em. Unlike most online poker calculators that use slow JavaScript Monte Carlo simulations, PlodAlong's calculator is powered by a dedicated C backend running on a Linux server — delivering fast, precise equity calculations across all supported game types.
Enter hole cards for 2 to 6 players, optionally add board cards at any street (flop, turn or river), then hit Calculate Equity to see each player's exact equity percentage. Cards are entered using an intuitive 4-colour deck picker — spades (black), hearts (red), diamonds (blue), clubs (green) — matching the colour coding used by most professional PLO players.
The standard form of PLO. Each player receives 4 hole cards and must use exactly 2 to make their best 5-card hand. PLO4 hands run significantly closer in equity than NL Hold'em — even very strong hands rarely have more than 70% equity preflop.
Each player receives 5 hole cards, still using exactly 2. The additional card dramatically increases hand complexity and equity runouts. PLO5 equity calculations are significantly more computationally intensive than PLO4 — this calculator handles them server-side for speed.
The most complex Omaha variant — 6 hole cards, still using exactly 2. PLO6 is offered on a small number of platforms but is becoming more popular for high-stakes play. Accurate PLO6 equity tools are rare — this is one of very few free calculators supporting it.
Standard Texas Hold'em equity calculation for up to 6 players. Useful for PLO players who also play NLH or want to compare hand equities across game types to better understand the structural differences between Omaha and Hold'em.
One of the most important concepts for PLO players moving from NL Hold'em is understanding why equity runs much closer in Omaha. In NLH, a hand like pocket aces has roughly 85% equity preflop heads-up against any random hand. In PLO4, the best possible starting hand rarely exceeds 70% equity against a strong opponent hand — and many premium vs premium matchups are extremely close to 50/50.
The reason is the number of possible hand combinations. The distribution of equity is far more even across hands So even when you get it in bad you will still have a much better chance of sucking out compared to NL. In PLO5 and PLO6, this effect is even more pronounced — the additional hole cards create even more combinations and make near-50/50 preflop equities common even between very different hand types. Understanding this is fundamental to building a correct PLO preflop and postflop strategy.
PLO equity is the percentage of the pot a hand is expected to win if the hand were played to showdown with no further betting. It is calculated by enumerating all possible runouts — every possible combination of remaining community cards — and determining what fraction result in a win for each player. At preflop with no board cards, this involves evaluating millions of possible board combinations, which is why a fast server-side calculator is significantly more practical than a browser-based simulation.
The calculator uses exact enumeration rather than Monte Carlo simulation, meaning results are precise rather than approximated. For preflop calculations, the C backend enumerates all possible board runouts to produce exact equity percentages. For postflop (flop, turn, river) calculations with fewer remaining cards, enumeration is even faster.
The key difference is the number of hole cards dealt and therefore the number of two-card combinations each player can use. PLO4 gives each player 6 combinations, PLO5 gives 10 combinations, and PLO6 gives 15 combinations. More combinations mean stronger draws, more vulnerable made hands, and equity that runs even closer between competing hands.
Yes — the calculator supports 2 to 6 players for all game types. For heads-up PLO calculations simply enter two players and the equity will reflect the true heads-up matchup. The PLO4 two-player calculation uses a dedicated fast endpoint that is optimised specifically for heads-up equity, making it particularly useful for HU PLO study and solver verification.
Yes, completely free with no registration required. PlodAlong is a PLO rakeback and training resource — the calculator is one of several free tools available on the site alongside a rakeback calculator and PLO training articles. There are no usage limits.
MonkerSolver is a full GTO solver that calculates equilibrium strategies across entire ranges, not individual hand matchups. This calculator is designed for spot-checking specific hand vs hand equity — useful for studying individual spots, verifying intuitions about hand strength, and understanding how equity changes across streets. The two tools are complementary: use this calculator for quick hand equity lookups, and MonkerSolver for full range vs range GTO analysis.
