You join Bill Cosby's creation in creating a surprise for each season in
Little Bill: Thinks Big. You start the game by choosing one of the four seasons. Then you go around Little Bill's house playing games and collecting items (that you get by winning one of the main five games) to finish the surprise for that season.
The main games consist of various pattern matching and counting skills. One of these games involves putting pictures in the proper order to tell a story, while another is looking at a card with a cookie drawn on it and making a cookie look just like it by placing various colored shapes in the proper places on said cookie. Another game has you taking control of Little Bill's submarine (in the bathtub) collecting gold coins. The last two involve putting Elephant's (Little Bill's pet hamster) tunnels together (color and shape matching) and placing the correct alien in the proper flying saucer (based on what aliens are already in the ship).
Once you have collected the five objects, Little Bill takes you to the backyard and he tells you how to finish the surprise he has been working on. After completing the surprise, you can add various objects to the scene -- these objects include things specific to that season (pumpkins for fall, rabbits for spring, etc.) as well as generic images that are in all seasons (letters, numbers, other animals).
There are also various smaller games throughout Little Bill's house. These will present questions like, 'Choose the red five' or 'which pile of acorns is bigger?'
The only real beef I had with the setup of the games is that you get the item the first time you beat one of the main games, and thus you get the item on the easiest setting. If the reason the child is going through the game is to find out what the surprise is for a particular season, then they won't have any motivation to go back to the games and play them again as they get more complex. It is typical in these educational games to have the child beat the game a few times (usually three) before they get whatever the goal for that particular mini-game is, and each time they go through it -- the mini-game gets harder.
It took me two and a half seasons before I realized that there were more difficult versions of each game. I didn't realize right away that the mini-games got more difficult if you went back and played them again even if you have already gotten the object. Once again, if the child is simply trying to get through the main objectives, they aren't going to get into the more complex games.
