I had a lot of fun playing with the Fisher Price Code-a-pillar. It’s amazing how all the pieces interlock using USB connections, and then it reads the pattern and moves according to how the pieces have been put together. The start/stop pads allow you (or your child) to create a challenge where the Code-a-pillar starts at one pad and the puzzle has to be put together in the correct way to get it to the end pad. It’s lots of fun to create an obstacle course and try to figure out how to put the pieces together so Code-a-pillar moves under and around objects set in its path.
The Code-a-pillar doesn’t move very well on carpets or soft surfaces since the wheels are rather small, but it can move right along on a smooth surface. I love that there are so many combinations to be tried with this toy.
