Other than boardgames, I also like to expose Isaac to such dexterity games. It's good for his development of his psycho-motor skills, reaction time, patience etc.
Found this fishing game which had really huge fishes. Unlike the usual ones. But I'd probably get him a usual one too, different kind of challenge, that.
Isaac enjoys this game a lot. Look at him :) We certainly got lots of mileage out of this game. Even till today, we still play it quite a bit.
Below is another simple game we play with Isaac - memory game!
