Fast Flip is a cute card game where you flip the cards and it teaches them a bit of matching skills. It’s really good that it’s the kind of thing that works for all ages.
Dr. Eureka’s Kaboom is a science game with “experiments”, which I also love the listing shows you: Fine motor skills, visual perception, focus and attention and processing speed. They have dozens of challenges that can keep your kids occupied for hours.
Lastly, check out Top That! which is a along the lines of Eureka’s Kaboom with various challenges.
I love that each of these games are different from the traditional board game and keep the kid’s mind running. It gets them involved and excited.
