On the Subject of That's The Fox
Failure to rotate the card clockwise around the deck before playing it.
This module presents an ordered deck of cards. Select the one and only invalid card by pressing the fox icon.
Note that the invalid card will be invalid on the previous card, the card after it will be invalid on it, and the card after will be valid on the previous card.
The first card is always valid.
A card is valid if and only if either of the following two conditions apply:
- It has the same rank as the previous card.
- It has the same suit as the previously played card, only when either it is a higher rank than the previously played card, or the previously played card is a Jack, Queen, or King.
