Another great family game is Triplica. The premises of this game is quite simple — just get 3 (aff) in a row. However, it's a lot harder than you think! You compete by trying to place cards to line up three in a row of the shape that matches your secret goal. The first player that scores five wins. However, placing a card that helps you may help your opponent (since you don't know what shape they are going for!). Triplica includes two multiplayer games and a highly addictive solitaire version.
There will be a lot of hooting and hollering when you play this game (and a few “yes!” when you play right into your opponents hand). Triplica combines a mix of strategy and luck and is a ton of fun.
