Gloomhaven Solo and Two-Player: Does It Work?

The campaign scales to any count, but the experience changes a lot. What to expect at each.

2026-08-09

Gloomhaven is cooperative, which means there's nothing stopping one person playing the whole thing. The scenarios scale properly to the number of characters, so the game is balanced at every count. The question is whether it's good at every count, and the answer varies more than the box suggests.

🎯

Quick Answer

Two characters is the sweet spot — fast turns, real tactical depth, easy to schedule. Solo works well if you control two characters rather than one. Four is the most epic and by far the slowest.

How Scaling Works

Every scenario specifies monster counts and difficulty based on how many characters are in the party, and the recommended difficulty is derived from average character level. Nothing is left to judgement — a two-character scenario is designed as a two-character scenario, not a four-player one with monsters removed.

What each count feels like

Count	Session length	Feel
1 character	Shortest	Tight and fragile — no cover for mistakes
2 characters	Fast	The sweet spot — real combos, quick turns
3 characters	Moderate	Good variety, noticeably slower
4 characters	Longest	Most epic, most downtime, hardest to schedule

Playing Solo

Solo Gloomhaven is genuinely popular, and it works for a specific reason: the monsters are run by a deterministic behaviour deck, not by a human opponent. There's nothing to hide and nobody to referee, so playing alone loses none of the game's integrity.

The one strong recommendation: run two characters, not one.

One character is brutally fragile. With no one to tank, heal or reposition, a couple of bad modifier flips ends the scenario.
The card system needs a partner. Elements generated by one character and consumed by another is where the system sings, and a lone character can rarely do both.
Two hands is very manageable alone. You're already planning both halves of the turn — controlling two characters is less than twice the work, and you lose the secrecy rule that exists purely to stop players over-coordinating.

Two Players

Two is where Gloomhaven is at its best as a shared experience. Turns come round quickly, there's almost no downtime, and coordinating two characters is complex enough to be interesting without becoming a committee.

It's also the most sustainable count in practice. Getting two people together regularly for a year is achievable; getting four together is a scheduling project — and campaigns die from scheduling far more often than from boredom.

Three and Four Players

Four characters is the biggest, most dramatic version of Gloomhaven — bigger maps, more monsters, party compositions that let each class do exactly what it's designed for.

It also has real downtime. While one player agonises over which two cards to commit, the other three wait, and the secrecy rule means they can't fully help without breaking it. Sessions stretch, and the difference between a two-character and four-character evening is closer to double than you'd like.

If you play at four, the single most useful habit is choosing your two cards while others are choosing theirs rather than waiting your turn.

Which Should You Plan For?

Be honest about the group you actually have rather than the group you'd like. A two-player campaign that meets weekly will get further, faster, and be more fun than a four-player one that meets when everyone's free.

And if you're buying for solo or two-player specifically, the case for starting with Jaws of the Lion is even stronger — smaller scenarios, faster setup, and a campaign length that one or two people can realistically finish. See which box to buy first.
