Got this for my 3 yo twin grandsons for Christmas and they are enjoying this like crazy. Their dad (my son) sits on the floor with them and sets up the pins for them to roll the ball to knock down. After an afternoon of play with these, we took the boys "big pins" bowling and they both had a blast! They are also using their counting skills to put it away ... 1, 2, 3 ... 10 pins and 2 balls to put away.
