In Far Cry 6, opening all of the Criptograma Chests not only rewards players with pieces of high-grade armor, but also nets them the "That's Puzzling" trophy/achievement.
There are 15 Criptograma Chests widely spread throughout the fictional Caribbean island of Yara, with each requiring players to collect two Criptograma Charts in order to open them. Here's a breakdown of the 15 Criptograma Chest and 30 Criptograma Chart locations in Far Cry 6.
Far Cry 6 Criptograma Chest and Chart Locations: Where to Find
Although the Criptograma Charts don't appear on the map, they are always close by to their chest. Around each Criptograma Chest, there are blue symbols that point you in the direction of their two corresponding Charts. Each chest and chart also have a subtle wind chime that helps in locating them.
Lastly, the Criptograma Chests and Charts aren't missable, meaning you can still find them after the story in free-roam. Keep track of which ones you’ve found in the Criptograma Charts screen via the Collection menu.
