Pragmata does not explain its Cabin Coin system well. You can finish the first couple of sectors without fully understanding what these coins do, where they come from, or why you should care. That's a mistake, because Cabin Coins feed directly into Cabin's Stamp Club, which is where some of the game's best weapons, costumes, mods, and hacking nodes are locked away. Here's everything you need to know to collect them efficiently and spend them on the rewards that actually matter.
How do you get Cabin Coins in Pragmata?
There are three repeatable sources of Cabin Coins, plus one free coin you receive automatically early in the game. According to Eurogamer's guide, Cabin itself hands you a free coin when you first unlock it at the Shelter after defeating the SectorGuard and picking up Shelter License Key 1. Think of it as a tutorial nudge. After that, you're on your own.

Safe Boxes
White and orange Safe Boxes scattered across each sector are the most consistent source. As Polygon's guide notes, the orange boxes in particular tend to contain Cabin Coins, while blue boxes generally hold only mods. The game does not mark which box type is in each sub-area, but you can open the regional map from the tram terminal to see how many boxes remain unclaimed in any given zone.
Many Safe Boxes are tucked into side paths or require short environmental puzzles to reach. Thorough exploration pays off here. Tracking your progress from the travel station terminal keeps things organized so you're not doubling back unnecessarily.
info
Blue Safe Boxes only contain mods based on available testing. Prioritize orange and white boxes when hunting specifically for Cabin Coins.
Read Earth Memories (REM)
Read Earth Memories are holographic globe collectibles scattered through each sector. Collecting one does not automatically earn you a Cabin Coin. You need to return to the Shelter and give the REM to Diana as a gift. Per both Polygon and Game Rant's guides, you receive exactly 1 Cabin Coin per REM gift given to Diana.
The collectible log tracks REM locations, but there is one detail worth knowing: the log lists a REM under the area where its hidden path begins, not necessarily where it physically appears. Polygon's guide specifically flags this with the first sector, where a REM visible in the initial area is logged under the third area because that's where the route to reach it starts. Check the log carefully rather than assuming the listed sector is where you'll find it.
Training Simulations
Training Simulations unlock after you upgrade the Shelter to level 2, according to Game Rant. The first batch of scenarios becomes available as the story progresses. Later simulations require you to find training simulation data in specific sectors, and the collectible log shows which areas contain that data.
Each simulation has a base clear requirement plus two bonus objectives. Some simulations reward a Cabin Coin just for clearing the base challenge. Others lock the coin behind a bonus condition, such as finishing within a time limit or completing the run without taking damage. Check the reward list before starting so you know exactly what you're committing to.
warning
Not every Training Simulation rewards a Cabin Coin for its base clear. Some require hitting a bonus objective, so read the reward screen before you start.
How to use Cabin Coins in the Stamp Club
Once you have coins, head to the Shelter and speak to Cabin. Select the "Stamp Club" option to access the bingo cards, called Stamp Boards. Each board is a grid of tiles, some showing visible rewards and others marked with a "?". Spending one Cabin Coin claims a single tile, whether hidden or revealed.
The mystery tiles are not randomized, as Polygon confirms. If you claim a hidden tile and dislike the reward, you can quit to the main menu, reload your save, and try a different tile instead. That's worth knowing before you spend coins blindly.
Clearing a full row or column triggers a bingo, which unlocks additional rewards displayed at the top of the card. These bingo rewards tend to be significantly better than individual tile prizes, with Cartridge Holders, Hacking Nodes, costumes for both Hugh and Diana, and even weapons available, according to Eurogamer's breakdown.
What about the red-blocked rows?
Most Stamp Boards have at least one row highlighted in red and locked. You cannot spend coins on those tiles until you clear the red zone in the associated sector. Hovering over a locked row shows which sector's red zone you need to complete. Some sectors have more than one red zone tied to different rows on the same card.
These locked rows are worth the effort. As Polygon's guide notes, they consistently hold some of the most useful rewards on the entire card.
danger
Completing Cabin's Stamp Boards is optional. You do not need to clear every board or find every Training Simulation. Target the specific rewards you want and ignore the rest if you'd rather focus on the main story.
Does completing every Stamp Board matter?
Not necessarily. The Stamp Club is a reward system, not a mandatory progression gate. You can aim for a specific costume or weapon, spend coins on the relevant tiles, and then move on. Polygon's guide explicitly points out that players are fine targeting only the rewards they want without feeling obligated to 100% every card.
That said, if you are going for full completion, the collectible log is your best tool. It tracks remaining Safe Boxes, REM data, and training simulation data per area, so you always know what's left and where to look.
