Review on Sudoku Small Thinking by Wood Expressions by Marc Cahoon

All the extra pieces I received were the same size as those in the original set. I don't know why they aren't in it because you can't play it until you have those extra parts. I highly recommend ordering them at the same time as the original box set. Updated 12/21/16. After starting a new game with extra mind tiles, I found I was missing a few more tiles for two numbers. I cut out little pieces of paper and wrote numbers on them, but it didn't work at all. Finally gave up and placed a SECOND order of thought pieces. It turned that $30 board game into a $50 board game.
