I'm playing right now on my K2, so they work there! Or at least, "Every Word" works. I haven't tried the other one yet, but it downloaded with no problem.
"Every Word" is kind of like the Jumble puzzle in the newspaper, or maybe more like when the substitute teacher would write HAPPY HOLIDAYS on the blackboard and tell you to make as many words as you could out of those letters. :-)
