This was played with by a child. All the blocks are shown in photos 1 and 2. Photo 3 is not the instruction manual. Assembly instructions can be downloaded from the internet. The center board in photo 4 is a different size than the original, as the correct size was unavailable. I believe there are no other missing pieces, but please understand that there is a possibility of oversight. ⚠️Additional Note⚠️ Some blocks have different colors. Please check photo 5. There is no box. The blocks will be disassembled for shipping. Thank you for looking.
