What a fun little game! Our two year old grandson loves assembling the sharks and sorting by color. Our three year old granddaughter loves that as well and also playing the memory matching game. We made it easier for her age level by preassembling the sharks with heads and tails and let the fin cards be used to flip and create a shark. Older children can play the game as directed by starting with fin tiles and looking for the heads and tails from the larger group of heads and tails that are arragned in an array in the middle. I am a former Kindergarten teacher and this little game hits mutiple levels of learning!
