The world of No Man's Sky hides many secrets and locations to explore, some of which can be found after solving a puzzle in the Transmission Tower, one of the points of interest on each planet.

These puzzles throw a lot of numbers at you that can be confusing at first, so here are all the Transmission Towers puzzles in NMS and how to solve them.
You can find Transmission Towers randomly on each planet or by using a Planetary Chart that leads to the inhabited outpost (red building icon). Inside the tower there is always a terminal with a sequence puzzle.
You must choose the correct number from the three options. Otherwise, you will be locked out and will not be able to get coordinates for a linked point of interest.
