Black Jacket Achievements Guide: All 42 Unlocks Explained

Black Jacket launched on May 12, 2026, and its 42 achievements tell you almost everything about how the game works. There are difficulty climbs, deck-building challenges, story endings, and some genuinely tricky mechanical feats hiding in that list. Only 14 players out of 10,887 have completed the full set, which puts the completion rate at effectively 0%. That number is honest: this is not a quick checklist.

What kind of game is Black Jacket?

Before getting into the achievements themselves, the context matters. Black Jacket is a blackjack-inspired roguelite deckbuilder developed by Mi'pu'mi Games GmbH and published by Skystone Games. The Steam description puts it plainly: gamble your way out of hell, play powerful card combos or cheat to outwit opponents, and earn Soul Coins to bribe the ferryman. It carries a Very Positive rating on Steam (83.54% positive as tracked by Steam Hunters), and it launched as a day-one Game Pass title on both Xbox and PC. If you enjoy strategy games with deep mechanical layers, this one rewards patience.

The 42 achievements break down into a few clear categories: hand-type wins, deck-building milestones, difficulty progression, story endings, and cumulative grind targets. Knowing which category each achievement falls into helps you plan runs rather than stumbling into them.

Which achievements should you unlock first?

The earliest and most accessible achievements reward you for learning the core hand types. Tattered Table asks you to win a round with a Flush (5 cards from the same suit), and 100% of tracked players have already unlocked it. Lost Finger (win a round with a Three of a Kind) and Sleeved 21 (play a card from your sleeve to hit exactly 21) both sit at 80% unlock rates among tracked players, making them natural first targets.

Coin String, which requires winning an entire encounter in a single round, and Thin Air, which requires winning a round where the bet held 15 or more coins, are slightly harder but still early-game realistic goals. Flaming Souls asks you to win a round using cards from 5 or more different suits, which pushes against the instinct to build a tight mono-suit deck.

Difficulty progression achievements

The difficulty ladder runs from 2 through 21, and each step has its own achievement. Here is the full sequence:

Note that the list skips from difficulty 10 directly to difficulty 21 for the final achievement (Ascension). Difficulties 11 through 20 do not have their own dedicated achievements, but you will need to climb through them to reach 21. Ascension has a 0% unlock rate on Steam Hunters at the time of writing, which reflects just how demanding the difficulty 21 run actually is.

How do you unlock the story achievements?

Black Jacket has four named story-ending achievements, each tied to a specific narrative outcome. Based on the achievement descriptions from TrueAchievements and Steam Hunters:

• The Family requires you to reunite with your family.
• The Vice requires having Morgan herself kill Virtue.
• The Shame requires finding the Vagabond.
• The Royals requires hanging the backstabbing murderer.

Three of these (The Family, The Shame, The Royals) have 0% unlock rates on Steam Hunters, while The Vice sits at 40% among tracked players. Morgan killing Virtue appears to be the most naturally encountered story outcome, while the others require more deliberate routing.

Relationship-based achievements feed into these endings. The Family Trio asks you to reach relationship level 4 with Better. The Shame Trio requires relationship level 3 with Ivel. The Vice Trio needs relationship level 2 with Morgan. There is also a hidden achievement called Memories that requires reaching relationship level 2 with Niv, and Escape (also hidden) unlocks by defeating the Reed boss once.

What are the deck-building and grind achievements?

Several achievements track cumulative actions across multiple runs rather than single-run feats. Plan for these as background progress rather than dedicated sessions.

Encounter wins:

• Tumors Suit: Win 50 encounters.
• Train Set: Win 80 encounters.

Card discovery:

• Intense Flames: Discover 20 artifacts.
• Propagation: Discover 40 artifacts.
• Dagger: Discover 50 cards.
• Greed Suit: Discover 70 cards.
• Shackles: Discover 100 cards.

Awakening and burning:

• Teeth Suit: Awaken 20 cards.
• Flames Suit: Burn 15 cards.
• Magnifying Glass: Burn 11 cards in a single journey (see bug warning above).

Boss defeats:

• Gain a Soul Coin: Defeat 3 realm bosses.

These stack naturally across normal play. Prioritize discovery-focused runs early to knock out Dagger, Greed Suit, and Shackles in parallel.

How do you unlock the hardest deck-building achievements?

Three achievements push against your natural instincts as a deckbuilder:

Sharpened Tool requires winning a journey without adding any new cards to your deck. This means running your starting cards all the way to the end, which demands that your base deck is already tuned to handle escalating difficulty. Testing this on lower difficulties first is worth it before committing a full run.

Zen requires winning a journey with no blank cards in your deck. Blank cards are dead weight, so this one rewards aggressive culling throughout the run.

Brute's Grasp sits at the opposite end: win a journey with 30 or more cards in your deck. Most deckbuilder instincts push toward leanness, so deliberately building a bloated deck while still winning requires a different approach, likely leaning on powerful individual card effects rather than synergy chains.

Vines asks you to have 21 awakened cards in your deck simultaneously, and Deep Sleeve wants you to sleeve 5 cards in a single turn. Safety Pin requires holding 8 or more artifacts at the same time.
