What does a "bingo" do?
In Pokemon Quest for Nintendo Switch you can achieve a bingo. When a Pokemon has three slots filled in a row (not on a diagonal) with stones, you get a certain bonus. But what bonus? The text explaining the bingo went by way too fast.
A bingo is also indicated by a white Pokeball on the left of the slots.
To see what the bingo bonus for a Pokémon is, click the magnifying glass button in the top-right of the same screen, to bring up the Pokémon's attributes screen. It is in the bottom middle of this screen.
