This games is challenging for all ages. Adults get into using many strategies during their plays and younger children develop strategies the more that they play. It is great that the game is challenging even though there is no verbal language needed to play. I think it is more fun than Scrabble!We played often with our family during the holidays and I ended up giving one of the Qwirkle games that I purchased to our son-in-law and our daughter to take home since they enjoyed it so much. Our son-in-law does not like to play games as a rule, but he is hooked on Qwirkle! I highly reccommend this game!
