The Family Pieces 350 is our latest and greatest offering for families who are looking to spend quality time together. The Family Pieces 350 include small, medium and large size pieces, however the distribution of pieces leans more to having large and medium size pieces. This allows for younger or less skilled puzzlers to contribute more equally to the assembling of the puzzle, while leaving fewer smaller pieces for the adults or more skilled puzzler. Plus, we increased the board size from 24" x 18" to 26.625" x 19.25" offering a larger puzzle size overall. This means more puzzle and bigger pieces for all ages to enjoy!
