Games That Play Themselves on Steam: You Plan, They Play
The short answer
Games that play themselves on Steam are the ones where you make the decisions and the game does the acting: you write a robot’s AI in Gladiabots, set an army’s formation in Mechabellum, or place cards along the road in Loop Hero while the hero walks it on his own. Start with Loop Hero. Its hero walks the loop and fights every battle by himself for the whole expedition, so you shape a full run without ever controlling him, and it has the most Steam reviews here, 36,576 at 92.7% positive (as of October 2026). For the strictest version, where you never touch a match at all, take Gladiabots.
This list means Steam video games. On BoardGameGeek the same phrase names board games with no real decisions, which is a different search.

What counts as a game that plays itself?
A game that plays itself is a video game where your decisions shape the action but never steer it: you set the rules, the team or the road, and the game plays out the fight on its own.
Most lists for this phrase stretch it further. Game Rant’s list and DualShockers’ list both include Dwarf Fortress and Final Fantasy XII, and Game Rant adds The Sims: games where the hands-off part is one layer under a game you still steer. Game Rant also has Progress Quest and Mountain, which ask for almost no decisions at all, and Cookie Clicker, which our list of games like Cookie Clicker covers. Game Rant’s pick Despot’s Game made my list too. For the rest I went to Steam games those lists skip and kept to six where the hands-off stretch is the core loop, sorted from the one where you program the most to the one where you barely visit.
For each I noted three things from its Steam store page (and, for Loop Hero and Farmer Against Potatoes Idle, its wiki): what you decide, what runs without you, and how long it runs before it needs you again. That last column is my reading of each game’s structure, not a timed measurement.
Which games play themselves on Steam?
| Game | What you decide | What runs without you | How long it runs alone | Regular price (as of October 2026) | Steam reviews, % positive (as of October 2026) |
|---|---|---|---|---|---|
| Gladiabots | Each robot’s AI, as a set of rules | The whole match | One match | $14.99 | 918 (87.7%) |
| Despot’s Game | Loot, classes and squad makeup | Every fight | One fight | $19.99 | 3,361 (84.0%) |
| Mechabellum | Units, upgrades and formation | The clash after you deploy | One clash, then you redeploy | $14.99 | 19,775 (83.6%) |
| Super Auto Pets | Which pets make the team | The battle | One battle, then you shop | Free, with in-app purchases | 36,229 (90.4%) |
| Loop Hero | Where to place cards, what to equip, when to retreat | The hero’s walk and every fight on it | A whole expedition, while you keep adding cards and gear | $14.99 | 36,576 (92.7%) |
| Farmer Against Potatoes Idle | Upgrades, talents and class | The farmer fighting wave after wave | While the game is open; the wiki marks the auto-recycler as working offline | Free, with in-app purchases | 8,197 (94.7%) |
| Sam, We Talked About This (ours · unreleased) | What to scrape, train and buy | The loop of models, subscribers and cash | Not announced | No price set | None yet |
Several of the paid games were discounted on the day I checked, so the prices above are Steam’s regular ones.
Which game lets you program the fighters?
Gladiabots
Gladiabots is the most literal answer to this search: you never control a robot during a match, you only write the rules it follows. Its Steam page describes building the AI of your robot squad, watching the robots carry it out in the arena, then fixing it and trying again, with “no programming skills required”. There are hundreds of solo missions, three modes (elimination, domination and collection), a sandbox where you control both teams, and asynchronous multiplayer, so a friend’s squad can fight yours while they are offline. It has the fewest reviews here, 918 at 87.7% positive (as of October 2026).
Which auto-battlers run the fight for you?
Despot’s Game
Despot’s Game is the pick if you want to build an army and then not touch it. Its store page calls the combat “indirect”: you equip a squad of naked humans with loot that turns them into wizards, cultists or ninjas, and then they “fight it out on their own” through procedural dungeons. Your decisions come between fights, and the store page says the point is tactics over reflexes. If your squad survives the labyrinth, it meets other players’ end-game builds.
Mechabellum
Mechabellum suits players who want the part they watch to be a full battle: you sit out every clash and act only in the deployment phase before it. On its store page you draft troops, customize them and set a formation, then the battle plays out in 3D; the page sums it up as “All strategy, no clickfest”. It is mostly a competitive game (1v1, 2v2 and free-for-all), but it also has Solo and Co-op Survival against AI waves. Of the paid games it is the only one with Steam’s In-App Purchases label, and it has the lowest share of positive reviews here, 83.6% (as of October 2026), a hair under Despot’s Game. Our post on games like Backpack Battles covers it next to games where you pack a bag instead of a battlefield.
Super Auto Pets
In Super Auto Pets the battle is the part that plays itself, and building the team before it is the part you play. Its store page calls it a “chill free-to-play auto battler”: you build a team of pets with unique abilities and battle other players, and “everything is at your own pace”. Arena mode is asynchronous with no timers: you try to reach 10 wins before you lose all your hearts. Versus mode puts 8 players in one live game. It has no single-player category on Steam, so every opponent is another player’s team. It is free to play with in-app purchases, and 36,229 reviews put it at 90.4% positive (as of October 2026).
Which games keep running for a whole run?
Loop Hero
Loop Hero gives you a whole run you shape but never steer, because nothing you do moves the hero. He starts at the campfire and walks the loop on his own, fighting whatever is on the road, as the Loop Hero wiki describes. You feed that loop the whole time, per its store page: a deck of cards that places enemies, buildings and terrain along each lap, and loot you equip on the fly. The real decision is when to stop: retreating at the campfire keeps all your resources, while retreating mid-loop usually costs you 40% of them (per the wiki, as of October 2026). It has the most reviews on this list.
Farmer Against Potatoes Idle
Farmer Against Potatoes Idle is the one you can leave running. Your farmer fights waves of mutated potatoes without you, and you come back to spend Potatoes and Skulls on more than 30 upgrades, according to its store page. It is an incremental game, and an incremental game is a game built around numbers that grow faster than you can spend them: you buy something that makes more of the resource, which buys more of that thing, until the scale changes and new systems appear. Our explainer on what an incremental game is covers how idle and incremental differ.
Each Reincarnation gives permanent bonuses and lets you switch between 6 classes. Later you can buy automation: the wiki’s Soul Shop page lists an auto quest completer, and marks the equipment auto-recycler as working offline. It has the highest share of positive reviews here, 94.7% across 8,197 (as of October 2026). If you want more games that run while you do something else, see our list of games to play while working.
Where our game fits
Our own game, Sam, We Talked About This, is the last row of the table but not one of the picks. It is an idle incremental game: you scrape data, train text, image and video models on it, let the models win subscribers, and put the cash into more disks, bigger machines and a bigger crew. Where the six above settle a fight or a run you set up, Sam’s loop is data, models, subscribers and cash: its Steam page says “The loop feeds itself and speeds up, and the models keep getting smarter”, with AGI at the end. It is unreleased, listed on Steam for Q1 2027 (as of October 2026), with no price and nothing to review yet. The Steam page for Sam, We Talked About This is live if you want to follow it.
Quick answers
What is the best game that plays itself? Loop Hero, for most players, because the hero runs a whole expedition by himself while you build the road around him. If you want zero input once a match starts, Gladiabots is stricter, and if you want something you can leave running, pick Farmer Against Potatoes Idle.
Are there free games that play themselves on Steam? Yes, two here: Super Auto Pets and Farmer Against Potatoes Idle. Both are free to play and both carry Steam’s In-App Purchases label (as of October 2026). Farmer Against Potatoes Idle is the one you can leave alone; Super Auto Pets wants a decision from you after every battle.
Which of these can I play on a Mac or on Linux? Five of the six on a Mac: Gladiabots, Despot’s Game, Mechabellum, Super Auto Pets and Loop Hero all list macOS on Steam (as of October 2026), while Farmer Against Potatoes Idle is Windows only. Four run on Linux, every Mac pick except Mechabellum.
Can I play these without other people? Yes, Steam lists single-player for five of the six. Super Auto Pets is the exception: every opponent is another player’s team. Mechabellum’s solo mode is Survival against AI waves, and a Despot’s Game squad that survives the labyrinth meets other players’ builds.
