I love Sequence. And there certainly is strategy involved. There is a multitude of options with each card you play. There are always several ways to try to complete your own sequence and you also have to chose between working on your own sequence while keeping an eye on your opponent and blocking their sequence. It gets even more interesting when you play partners. I do like Chess as well but I'm not that good at it, my father-in-law always wins. I get so busy plotting my attack that my defense suffers.
