11. Aven's Corner
Aven's Corner has free preschool games that are sorted by levels of skill as well as theme. There's a great selection of instructional games, games that allow kids to explore and educational games that teach pre-reading, matching and memory skills.
I love how big the game screens are at Aven's Corner. You can even make them full-screen if you want!
13. Building Blocks
There are only a few free preschool games at Building Blocks. However, all the games are very well designed and each game is sure to hold your preschooler's attention for a long time.
There are also a few multi-player games here which is great if you have some preschoolers not wanting to wait their turn.
14. Treehouse TV
Treehouse TV has got some very fun free preschool games that features all sorts of kids' TV characters. Just click on a character and then you'll see a list of games, videos and coloring sheets that feature that character.
There are both educational and fun games here at Treehouse TV - enough to keep your preschooler occupied for an afternoon!
