Remnant Decryption Puzzle Guide

Remnant decryption puzzles are encountered during Pathfinder Ryder's travels in the Heleus Cluster. Puzzles are found on locked Remnant technology on all planets of the Heleus Cluster. The puzzles consist of a grid of Remnant Glyph symbols that must be organized in the right order to unlock the Remnant technology and its reward.

Mechanics
When Ryder attempts to interface with a puzzle, an interface will open showing the decryption puzzle.
 * Puzzles consist of a 4X4 or 5X5 grid of Remnant Glyph symbols. Red symbols are locked in place and blue symbols Ryder can change.
 * Glyphs cannot repeat on any horizontal or vertical straight line.
 * Glyphs cannot repeat within the boundaries of the interior blue lines of the puzzle grid.
 * Each decryption puzzle has a unique fixed solution that does not change.

Certain puzzles are missing symbols and this will be indicated by ? symbols. Ryder will be required to scan the surrounding area using the scanner for the missing Glyphs. No Research Data (RD) is given for scanning a Glyph.

Submitting an incorrect solution to the puzzle will immediately summon Remnant forces around Ryder which will have to be defeated before Ryder can attempt to solve the puzzle again. Each incorrect solution will summon forces.

In order to accelerate the process of solving a puzzle, Remnant Decryption Keys can be used to bypass the decryption and automatically enter a correct solution for the puzzle. However, these are expensive items that can be sold for a large amount of and should potentially be saved. While the in-game description of a Remnant Decryption Key says that all consoles can be bypassed, two puzzles can't be bypassed.

Rewards
Depending upon the specific puzzle being decrypted, different rewards are received but center on the following three concepts:
 * Game Progression - Some puzzles are required to continue the main story or side missions progression and have to be completed.
 * Valuable Loot - A number of the puzzles are for locked containers or open access to areas that contain rare valuable items.
 * Skill Points - A few puzzles reward free bonus skill points.

Completing 20 puzzle solutions in a single playthrough will award the Cryptographer Achievement.

Puzzle Solutions
Each mission page with a puzzle has section of text describing if additional Glyphs need to be scanned, if the puzzle can't be bypassed, and a link to the "Puzzle Solution" section at the bottom of the page with a picture of the completed puzzle (or puzzles). The list of puzzles below is a quick reference of all puzzles and solutions that can be encountered. Refer to each mission for the specifics of the location and any puzzle requirements.

Trivia

 * Remnant Puzzles may be compared to the Sudoku mechanism.
