The Clue Giver must lead the Guessers to identify one Secret Card by playing other cards from their hand as Clues. There are two kind kinds of Clues: Remove Clues (cards played horizontally, which have something similar to one or more cards the the Guessers should remove) or Keep Clues (cards played vertically, which have something similar to one or more cards the Guessers should keep).
For example, the Secret Card is the Tyrannosaurus rex. You could play the Velociraptor as a Keep Clue, to suggest to the Guessers that the cards to keep are dinosaurs, carnivores, or were featured in the original Jurassic Park movie from 1993. Or, you might play the Mosasaurus as a Remove Clue, to point out that the cards to remove are marine animals, gigantic, or are featured in the modern movies… it will be up to the Guessers to understand what the Clue Giver is trying to suggest!
There are different versions of Similo! If you have more than one, you can combine two different decks of cards to create new and interesting strategies! Just choose two versions of Similo and use one as the Guessing deck and the other as the Clue deck. Will you guess which prehistoric creature from the Jurassic World franchise has something in common with the Cat, the Dog, and the Wolf from Similo: Animals?
