The full Stonemachia achievement list, broken down
Stonemachia packs exactly 30 Steam achievements into its run, and the list reads like a tour through everything the game has to offer: boss kills, collectibles, environmental gags, and a secret disco. Most achievements unlock naturally through progression, but a handful require deliberate detours. This guide covers every single one so you know what to expect before you miss something missable.
All 30 achievements listed
What are the story progression achievements?
The bulk of the list ties directly to boss defeats, and clearing the main path will hand you most of them. Each boss has its own achievement with a distinct name, so tracking your progress is straightforward.
Here is every boss-kill achievement in the order they appear on the list:
That is 15 achievements just from boss encounters. Coming to Life is the one to watch here since it requires clearing every paintings boss rather than a single named target, so make sure you are not skipping any optional encounters in that category.
Derasin appears twice in the achievement list. The second encounter (... Et In Terra) is a separate fight from the first, so do not assume the earlier kill counts for both.

How do you unlock the collectible achievements?
Two early achievements gate the collectible side of the game. Opening Hand unlocks when you find the first card, and Opening Track unlocks when you find the first vinyl. These are essentially tutorial pickups that signal there is a full collection system running in the background.
The payoff for going all the way is Minstrel Deck Builder, which requires finding every card and vinyl in the game. This is the kind of achievement that punishes players who rush the main path without exploring side areas, so start picking up collectibles early rather than trying to backtrack later.
Treat every new area as a potential collectible location. Cards and vinyls can appear in spots that are easy to walk past, especially if you are focused on reaching the next boss.
What are the secret and optional achievements?
This is where the list gets interesting. Several achievements exist purely for doing things the game never explicitly tells you to do.
- Pigeon Boxing requires you to hit a pigeon. That is the entire requirement.
- Iron Deficiency unlocks by getting hit by a tram. Deliberate self-harm for achievement purposes.
- Mouse-slaughter needs you to knock a mouse off a ledge.
- Meow is triggered by letting a cat pet you.
- Mother's Eye unlocks when you enter Mother's World.
- When the Cat's Away... requires dancing in the secret disco.
The secret disco is the standout here. Finding it is the challenge since the game gives no directions, and it sits in the same category as the kind of hidden rooms that dedicated explorers find by checking every wall. After spending time in the game's environments, the areas with unusual architecture tend to be worth a second look.
Mother's World is a named location that suggests a significant optional area. Reaching it counts as its own achievement separate from any boss kills that might happen inside.
How do you unlock the progression system achievements?
Gambit unlocks when you unlock one Angelical Armour, making it one of the earliest non-story achievements you can grab. The deeper version, Paid the Sculptor a Visit, requires reclaiming all your Angelical Armours, which implies the armour system involves losing and recovering pieces rather than simple linear unlocking.
Out of Book Moves needs every skill unlocked. This is a completionist target that likely requires thorough exploration and enough resources to purchase or earn every skill in the tree.
Paid the Sculptor a Visit unlock
What does 100% completion look like?
Two achievements sit at the top of the completion pyramid. Checkmate unlocks for completing the game, which means seeing the credits. People Pleaser unlocks for getting every other achievement, making it the true 100% marker.
The full breakdown of achievement categories:
Because People Pleaser requires all 30 achievements, you cannot miss anything. The secret disco, every pigeon hit, every armour piece, and every card and vinyl all count toward the final unlock.
For players who want to go beyond this guide, the Stonemachia guides collection has additional strategy resources covering specific systems in more depth. Stonemachia sits firmly in the action games space, and the achievement design reflects that with a heavy focus on combat encounters alongside the exploration content.
The 30-achievement list is well-structured for a first playthrough with optional layers for completionists. Clear the bosses in order, pick up every collectible you see, and deliberately seek out the environmental gags like the pigeon and the tram. The secret disco will take more effort, but it is the kind of discovery that makes the hunt worth running.
