We have played it only a few times.  I bought this game for my 5 year old son with not so good memory to practice it.  We do many varieties of memory games as long as my son loves it.  This memory type game was a hit with all 3 of my children: ages 11, 8, and 5.  They played it many times and we've had it only for 2 days :).  The only bad thing I have to say is it's durability.  Board is good, but the little cards are the type you punch out, they have little nobs on sides and cards are thin.  To make this game last longer I glued all cards onto cork lining with an adhesive backing.  It works great, cards will last longer this way.
