The Domino Block Set by BigOtters contains 108 high quality wood pieces in 10 colors with 10 blocks each. There are 7 additional blocks and 1 domino space included as well. Everyone in my house enjoys playing with these blocks. We build and we make domino rows and have spent hours creating and having fun. I am very pleased with this purchase and if we expand we will be coming back for a second set. Definitely recommend this 5 star product.
