Opis w języku angielskim:
If Then is a game of co-operative pattern solving.
One player is the knower, who reads the hint, and tells the other players whether their guesses are right or wrong. Everyone else is a guesser; they take turns choosing a card from a display and placing it in the line as a guess. The guessers win if they successfully guess the hint before running out of cards.
Hints may be based on the size, value, and/or color of the number and background. Higher level cards offer more complex hints.
