I started playing Clear it 3 two years ago.. I played it from level 1 till the end over and over and over again.. I never realized there were more to buy and play.. I almost own them all now.. and I will continue to play them over and over and over. I just love these games.. they are the only games I found that you dont have to pay for extras.. you don't have to watch a clock and you can get lost in time playing them.. Fascinating games.. will keep buying as long as they make them .. at age 65 still going strong...
