Finding Dory features the same gameplay as its parent Dobble but in a simplified manner so that younger players can play, too.
Each card in Dobble: Finding Dory features six different animals, with the sizes of animals varying from one card to another. Any two cards have exactly one animal in common. To play, reveal one card, then another. Whoever spots the animal in common on both cards claims the first card, then another card is revealed for players to search, and so on.
Whoever has collected the most cards when the deck runs out wins!
Unfortunately, there aren't any reviews of Dobble: Finding Dory, but you can watch this video to see the general gameplay of Dobble!
