I recently purchased Elefun and Candyland for my 2 1/2 year old. He loves Elefun, but I am disappointed because the butterflies last about a minute then it is about 3 to have him pick them up, put them back in and start over. But like I said for some reason, he loves it.
Candyland is also great. We have played it a couple of time and he is starting to get the 'take turns' theory. Plus it helps learn colors.
I have a memory deck I got from the dollar store and it is still kinda hard for him. He gets he needs to find the matches, but flips over multiple cards to find it. Plus he is a little 'rough' with the cards and tries to bend them when he gets excited.
I also have a Hot Diggity Dog game that will help them to count (audio barking 1,2,3 so not as complicated as 1-6 in chutes and ladders), and colors. Another taking turn game, but whatever bone you land on goes to that dog, regardless of what color dog you are. (So, if you are the blue dog land on a green bone, the green doggie gets the bone YEAH!)
Isn't it so much fun when they can start playing games with you! I love it.
