I have always enjoyed doing jigsaw puzzles. Many years ago my Siamese cat would steal one piece, only one piece from every puzzle. I assume she felt ignored. I learned about this because one day she put something at my feet and rolled over. Upon examination I found a very chewed piece from the last puzzle. I can only assume she ate all the other the other single pieces from my puzzle inventory. A jigsaw puzzle sent me on a quest for retirement property which my husband and I found in Maine. I'm definitely addicted to Jigidi. I looked a long time for puzzle software or an on-line puzzle site. Thank you creators of Jigidi.
