Pokémon Scarlet & Violet are filled with ominous stakes, and sealed vaults. If you’re asking “what are the stakes all about?” then it’s possible that you just haven’t progressed through the game enough quite yet – but they’re part of a new puzzle, one that will result in you gaining access to the Treasures of Ruin, a brand new quartet of Legendary Pokémon.
If you want to catch ‘em all, as is the goal, then you’ll need to find all of the colored stakes that you’ll find around the game. There are eight stakes of each color, and a vault relating to each of the four colors. If you want to find all the stakes, unlock all the vaults, and catch all of those Legendary Pokémon, you’ll need to follow these instructions in Pokémon Scarlet & Violet.
