In the lunar wasteland of Pragmata, survival against the hostile AI IDUS is just the beginning. Eventually, your path will lead you back to the Refuge, your sanctuary against the Lunafilament corruption. It is there that you will meet Cabin, an independent support robot who manages the Stamp Club, the heart of the game's progression system.
Many players face a critical shortage of Cabin Coins, the resource required to unlock rewards on the Stamp Club's bingo board. Unlike other resources, these coins are not dropped by common enemies; they are designed to reward exploration and game mastery.
Why are Cabin Coins scarce?
If your coin counter is at zero, it may be due to several mechanical reasons:
- Refuge Level: Cabin and the Stamp Club are not activated until you complete the prologue and reach level 1 of the Refuge.
- Lack of exploration: Coins are tied to specific objects like Orange Safes and Earth Memories (REM). If you move too quickly through the story, you will miss them.
- Combat Skill: A large portion of the supply is locked behind Training Simulations, which require you to meet specific objectives.
- Manual Interaction: Coins obtained through REM are not automatic; you must manually deliver the item to Diana in the Refuge.

Fast route for impatient travelers
Need to complete a bingo row right now? Follow these steps:
- Gift the Balloon: If you finished the Prologue, give the REM Balloon to Diana to instantly obtain 1 coin.
- Simulation 1-1: Complete the first basic combat trial to earn up to 3 Cabin Coins.
- Orange Boxes: Look for containers of this color in any sector; they have the highest probability of containing coins.

The three pillars of collection
1. Search for Orange Safes
These are the main collectible items. Upon reaching Refuge Level 2, you unlock Item Scanning. Use it to highlight containers through walls. Always prioritize orange boxes (coin prizes) over yellow ones (upgrade components).
2. Training Simulations
Available in the Simulation Capsule (Refuge Level 2). Each simulation has three sub-objectives (such as finishing in record time or taking no damage). Completing each objective grants you 1 Cabin Coin. If a challenge is too difficult, upgrade Hugh's suit and return later.
3. Earth Memories (REM)
These appear as blue holographic globes in sectors 01 and 02. When you find them and deliver them to Diana in the Refuge, the REM Replicator will print a toy and Cabin will grant you 1 coin as a bonus.

Strategy in the Stamp Club: The Triple Bingo
Don't spend your coins randomly. To maximize your gear, follow these recommendations:
- Aim for intersections: Unlock central squares that allow you to complete horizontal, vertical, and diagonal rows simultaneously.
- Completion bonuses: Completing an entire card usually unlocks legendary modifications or unique outfits for Diana.
- Strategic saving: Do not spread coins across multiple cards at once. Focus on one until you get the bingo bonus to obtain the best gear quickly.

Pro Tip: As you progress to Sector 03, the cost per stamp increases. Try to enter new areas with a savings of 5 to 10 coins to instantly unlock new weapon blueprints as they appear.
Alternative methods and collecting
If you prefer to avoid direct combat, there are other ways:
- Diana Amiibo: Released in April 2026, you can scan it once a day for supplies with a chance to include Cabin Coins.
- Hacking Nodes: Return to Sector 01 once Diana has Level 3 hacking skills to open safes that were previously inaccessible.
- Red Zones: Completing these highly corrupted areas doesn't give coins directly, but it unlocks the "locked" red bingo squares that often contain the highest value rewards in the game.
