Over the past decade or so, classic card games have been reimagined with online games and apps. Duo Cards online is a mobile version of this family friendly classic. If there is no family around to play with you, you can take on the AI, or the computer. In both versions of the game, you start out with a hand of cards. The object is simple, but can be challenging. You must carefully match up the cards that have already been played with cards of matching numbers or colors. Sort of like Uno, but the cards are made with two numbers each, a top number and a bottom number, also with a different color, not to each card, but to each number. This game is family friendly, so feel free to take on friends and family in this mobile version of a beloved classic card game. Have a family night to challenge one another to a card game, or work together to defeat the AI! Either way, this game is a good way to test your attention and logic.
