The ultimate way to solving the alien puzzles is to avoid duplicating any alien symbol in any row or column. That is how Sudoku puzzles are solved. However, these are trickier than the latter since there are multiple boxes that are empty rather than filled. It will require them several tries in order to get every symbol right.
There are also instances where they may encounter question marks and not symbols. It only means that they still need glyphs that are required in solving them. They can ask SAM to help them find the glyphs around the area.
They should never forget that repetition of shapes will not help them to solve the puzzles. The rule will be applied to every vault or monolith found at Eos, Havarl, Kadara, Elaaden, Voeld, Khi Tasira and H-047c terminals.
