The best Pandemic expansions and versions, ranked

How hard does Pandemic get? We left the world alone and timed it

Pandemic has one difficulty dial: the number of Epidemic cards in the player deck. Introductory uses 4, Standard 5, Heroic 6. On the Brink adds Legendary with 7. Every Epidemic speeds up the infections and throws 3 cubes on a fresh city.

To see what one more card really does, we played the decks with nobody at the table. No treating, no cures, no events. Just the infection deck, the Epidemics and the outbreaks, following the rulebook to the letter, on the real map.

That gap is the honest measure of difficulty, so we turned it into the "How hard it gets" meter in the ranking below: the share of untreated worlds that are gone by turn 8, out of 10. Each extra Epidemic adds a point or two. Legendary is not a small step up from Heroic.

Why double Epidemics (almost) never happen

The setup rule everyone rushes through is the clever part. You split the player deck into as many piles as there are Epidemics, shuffle one Epidemic into each pile, and stack them. So there is exactly one Epidemic per stretch of the deck, and they can't bunch up the way a plain shuffle would allow.

Two Epidemics in one draw can only happen when your 2-card draw crosses the seam between two piles. Whether that is possible at all depends on whether the piles have an even number of cards. At Standard with 2-4 players they always do, and so does Legendary with 4. Hover the orange marks to see where Heroic's seams fall.

The split also protects you from the worst streaks. Shuffle the 5 Epidemics anywhere and 69% of games would have two of them in the same or the next turn. With the piles it is 16%. Three Epidemics within three turns, which a plain shuffle produces 16% of the time, cannot happen at all.

The deck math has one more lesson, about what an Epidemic does to the cities that were already infected. It is the rule that loses most first games, so we put it in Pandemic vs Pandemic Legacy.

The ranking

We ranked by how much good Pandemic each box gives you: how long it stays fresh, which groups it works for, how far it pushes the difficulty, and whether you can still buy it new (as of November 2026). "Replay value" and "Easy to teach" are our ratings. "How hard it gets" and "Sessions" are computed. Hover any meter to see what feeds it.

The spin-offs and Pandemic System games

Z-Man now calls the engine the Pandemic System and puts it under other themes, sometimes without the word Pandemic on the box. These are good games, but they are their own thing, so we didn't rank them against the boxes above.

How we ranked, and what we computed

The ranking is our editorial call, weighted toward replay value, player range and how much a box changes the game, and away from novelty. Product facts (players, years, minutes, availability) come from Z-Man Games' product pages, the rulebooks and BoardGameGeek, as of November 2026.

The deck numbers are exact. Each Epidemic sits uniformly at random in its own pile, so we enumerated every possible layout of the player deck with its exact probability. For the "leave it alone" curves we simulated 200,000 worlds per setting on the real map (93 connections between 48 cities), with the outbreak, chain reaction and cube-supply rules checked by tests against the rulebook. Nobody acts in those worlds, so they measure the pressure of each setting, not your chances of winning. Expansions that change the player deck in ways we did not model (State of Emergency, In the Lab, the Legacy seasons) get no "How hard it gets" meter. More on how we work.

Spot check: an untreated Standard world sees its first outbreak in turn 4 (median). The deck turns: Introductory 24, Standard 25, Heroic 25, Legendary 27.
