Gloomhaven solo play is one of the deepest solo dungeon-crawling experiences available, but it can also be one of the most intimidating. Between setup, monster management, and card-driven tactical combat, success depends on preparation as much as strategy. The good news? Once you understand the system, solo play becomes deeply satisfying — a pure test of decision-making with no one else to blame (or credit).
This guide covers everything you need to know: how to set up solo play efficiently, how to manage the game without getting buried in logistics, and how to win through smart card play and initiative planning.

Understanding Solo Play in Gloomhaven
Before anything else, it’s worth clarifying what “solo play” actually means in Gloomhaven, because there are two distinct experiences to choose from.
The first is standard campaign play with a single person at the table. You control multiple characters — typically two — working through the full campaign as you normally would with a group. This is the most common solo experience, and it’s what most players are doing when they say they’re playing Gloomhaven solo.
The second is the official solo scenario book, which contains 17 class-specific missions. These scenarios are designed for exactly one player controlling exactly one class, and they’re meant to push you to your limits with that character. They’re locked until your town reaches prosperity level 3 and two characters have been retired, so they come later in the campaign rather than at the start. If you enjoy games that feel like puzzles more than tactical slugfests — and you’ve already spent serious time with a character — these missions deliver a uniquely focused challenge.
For players just starting out, the full campaign with two characters is where you want to begin. It gives you the systems exposure you need without the administrative overhead of running three or four characters simultaneously.
Setting Up Solo Play Efficiently
Gloomhaven has a well-deserved reputation for complex setup. The box is enormous, the component count is high, and the sheer amount of monster management creates real overhead before you’ve played a single card. Solo play adds a wrinkle: you’re handling all of that yourself, which makes streamlining the process genuinely important.
How Many Characters Should You Control?
Community consensus points firmly toward two characters for solo play. Two characters cover the core strategic bases — damage output, survivability, mobility — without creating a decision bottleneck where you’re managing too much per round. Three or four characters increases cognitive load sharply, especially early when you’re still learning class cards.
Two characters also keeps the physical table footprint manageable. Gloomhaven takes up a lot of space even with two character boards in play, and adding more pushes you into territory where you’re constantly shuffling things around just to see the board.
Use the Gloomhaven Helper App
This is the single biggest quality-of-life improvement available for solo play. The Gloomhaven Helper app handles monster AI, ability cards, and stat tracking automatically. What would otherwise be a stack of monster ability decks and a constant stream of math becomes a few taps per round.
Solo players who don’t use the app consistently describe setup and cleanup taking longer than the scenario itself. The app cuts that dramatically. It also reduces the mental load during play, which matters because solo Gloomhaven already demands full attention for your own character decision-making.
Organize in Advance
Keep your character boards, hand cards, and modifier decks pre-sorted between sessions. If you’re playing the same campaign over multiple sessions — which you will be — having everything ready to pull out and play reduces friction to near zero. Bag your monster sets by type, label your scenario components, and resist the urge to break everything down between sessions unless you genuinely need the space.
For Jaws of the Lion specifically, the scenario book format handles setup for you. Follow it chapter by chapter, pull only the components the book calls for, and don’t try to get ahead of it. The step-by-step structure exists precisely to make the experience accessible.
How to Manage the Game Without Slowing Down
Solo play creates a unique tempo challenge: every decision about both characters falls on you. In a group, you discuss options, divide the thinking, and move faster collectively. Solo, you’re running the whole operation. Without structure, rounds can stretch uncomfortably long.
Plan Initiative as a Pair
The most effective approach is to pick cards for both characters before committing to either. Consider what you want to accomplish this round — who needs to move, who needs to attack, who might need to rest — and plan your initiative numbers together. You’re looking for sequencing that makes tactical sense: getting your tank into position before your damage dealer swings in, or setting up an attack with one character that your second character can capitalize on.
Initiative planning is the core cognitive task of each round, and it’s where the most time disappears if you’re undisciplined. Give yourself a time limit if you find rounds dragging. Most experienced solo players pick cards within 60 to 90 seconds and refine on the fly.
Keep the Board State Clean
Between each round, take 30 seconds to tidy the board. Reset monster positions clearly, confirm damage tokens are correctly placed, and make sure modifier decks are accessible. Small amounts of board drift — a monster that’s one hex off, a damage token on the wrong figure — compound into confusion fast when you’re the only set of eyes watching everything.
This habit also functions as a mental reset. Picking up a clean board state at the start of each round helps you plan faster.
Know When to Rest
Hand management is the mechanical heartbeat of Gloomhaven, and solo play forces you to manage two hands simultaneously. The temptation is to push both characters hard, spending powerful cards aggressively to finish scenarios faster. That works until it doesn’t — and when one character exhausts unexpectedly, you lose half your combat effectiveness at the worst possible moment.
Track both characters’ card counts at the start of each round. If either character is approaching eight or fewer cards, plan a short rest into that character’s round rather than waiting until it’s forced. This keeps your options open and prevents the scenarios from turning into a slow-motion collapse.
Winning Through Hand Management and Initiative
Gloomhaven’s combat rewards planning and positioning more than aggression. The players who win solo scenarios consistently are the ones who understand this rhythm and play to it rather than against it.
Treat Card Loss as a Resource
Every Gloomhaven character has powerful cards marked with a loss icon — play them and they’re gone for the scenario. Newer players often hoard these cards, treating them as emergency tools. More experienced players treat them as a finite resource to spend at the right moment, not the desperate moment.
In solo play, identifying when to spend a loss card matters even more because there’s no teammate to compensate if you blow one at the wrong time. A good general rule: loss cards belong in rounds where you can guarantee they’ll shift the scenario’s trajectory — eliminating an elite enemy before it attacks, reaching an objective before reinforcements arrive, or breaking a room’s AI sequencing in your favor.
Positioning Wins Scenarios
Monster AI in Gloomhaven follows predictable patterns. Enemies move toward the nearest target, attack when in range, and apply special conditions on specific ability cards. Once you understand how each monster type behaves, you can position your characters to funnel attacks, split attention, or pull enemies into locations that neutralize their effectiveness.
In solo play with two characters, you have a significant positioning advantage: you decide exactly where both characters stand after every move. Use this deliberately. Push your damage dealer into flanking positions, keep your more vulnerable character at range, and use the dungeon’s corridors and doorways to choke enemy movement. This approach lets you punch above your weight class against scenarios that seem designed for larger parties.
Think One Round Ahead
The best single habit you can develop for solo Gloomhaven is planning your next round’s cards during the current one. While monsters are resolving their actions, you already know roughly what you want to do next — which gives you the mental space to spot problems before they become crises.
This forward planning matters especially for the official solo scenarios, which are designed as precision puzzles rather than brawls. The solo scenario book describes them as tests of class mastery: they reward tight execution and punish reactive play. If you approach a solo scenario expecting to improvise your way through it, you’ll exhaust your characters well before the scenario ends.
Class Selection for Solo Play
If you’re playing the full campaign solo, your starting character choices shape the entire early game experience. The goal is a party that covers survival, damage, and ideally some crowd control — because in solo play, there’s no teammate who can compensate for a gaping weakness.
Avoid building two characters that do the same thing. Two pure damage dealers will tear through normal enemies but collapse against scenarios with sustained pressure or healing requirements. Two defensive characters will survive long scenarios but struggle to complete objectives before the round limit forces exhaustion.
The Brute and Spellweaver pairing is a classic starting combination because it covers survivability and burst damage naturally. As you explore more characters, focus on synergies that complement your play style rather than chasing perceived tier rankings. Many classes that look weak in theory excel when you understand their cards deeply — and the solo scenarios are specifically designed to reward that depth.
For players interested in the broader ecosystem, exploring alternatives to Gloomhaven can also clarify what makes Gloomhaven’s design distinctive versus other dungeon crawlers in the same space.
The Official Solo Scenarios
The 17 class-specific solo scenarios unlock after prosperity level 3 and two retirements. Each one is built around a single class and designed to expose both the strengths and weaknesses of that character’s card set.
These scenarios don’t play like regular Gloomhaven scenarios. They’re shorter, tighter, and more mechanically constrained — the kind of experience where a single mistake in round two can cost you the win three rounds later. Think of them less as dungeon runs and more as mastery tests.
Completing them gives you a real sense of how deeply you understand a particular class. If you find yourself breezing through a solo scenario, it’s a sign you’ve genuinely internalized that character’s toolkit. If you’re struggling, the scenario is showing you exactly where your knowledge gaps are.
Players who have put significant time into their Gloomhaven party composition and character synergy will find the solo scenarios a natural next step — a chance to test whether that understanding holds up when the support structure of a full party disappears.
Solo Play and Table Space
This is a practical consideration that doesn’t get enough attention: Gloomhaven needs a lot of table. Two character boards, a dungeon tile spread, monster decks, modifier decks, initiative trackers, and the scenario book all compete for the same surface.
If you’re working with limited space, a few adjustments help significantly. Use the Helper app to eliminate physical monster decks entirely. Keep the scenario book open on a separate surface — a chair, a nearby shelf — rather than trying to integrate it into your play area. And if you’re playing on a smaller table, set up the dungeon incrementally as you enter new rooms rather than revealing everything at once.
The cooperative strategy games buying guide has useful context on how Gloomhaven compares to similar games in terms of table footprint and component intensity, which is worth checking if you’re weighing your options before committing to a full campaign.
Building Your Solo Campaign
Solo Gloomhaven is a long-form commitment. A full campaign runs to dozens of scenarios, multiple character retirements, and a story that evolves based on your decisions. Going in with a plan helps.
Decide early how you’ll handle character retirement and class unlocks. The temptation is to stick with your original characters indefinitely, but the retirement system exists to push you toward new experiences. Retiring characters on schedule expands your options, increases town prosperity, and unlocks the solo scenarios faster.
Track your scenario outcomes carefully. Solo play means every decision about branching scenario paths falls on you — there’s no group vote. Write down why you made the choices you did, especially early in the campaign. Gloomhaven’s narrative branches can be subtle, and having notes makes revisits more coherent if you step away from the campaign for a few weeks.
For players interested in expanding their dungeon-crawler collection beyond Gloomhaven, games like Spirit Island and other high-complexity cooperative titles scratch a similar itch. The Spirit Island strategy guide is worth reading if you want another cooperative experience that rewards deep strategic planning.
What Makes Gloomhaven Solo Play Worth It
Solo board gaming has expanded dramatically in recent years, but Gloomhaven remains one of the benchmark experiences — a game that translates its cooperative complexity into a solo format without losing what makes it special. The best solo board games guide covers the full landscape if you’re building a solo gaming library, but Gloomhaven occupies a category largely by itself.
The depth of the card system, the variety of character classes, and the campaign’s narrative momentum give solo play a satisfying long-term arc that shorter games can’t replicate. The setup overhead is real, but the payoff — a genuinely challenging tactical puzzle that evolves over dozens of sessions — is worth the investment.
If you’ve been hesitant to start Gloomhaven solo because it seems like too much to manage alone, the two-character approach with the Helper app removes most of the friction. The hard part isn’t the logistics. The hard part is making good decisions under pressure, and that’s exactly what makes this game worth playing.
