In the end, while there is clearly casual appeal to Connect Four and the entire Hasbro Family Game Night line-up, this is really a game that can be enjoyed by anyone. It won't entertain you for long, but the bite-sized games are perfect for killing time, and surprisingly addictive.
Difficulty can be adjusted, as well as number and length of rounds in the new modes, so you can really make Connect Four whatever you want it to be. It's cheap, it's simple, it's quick fun, and it's worth ten dollars if you like the original board game. Connect Four won't blow your mind, but you will find yourself saying "just one more game" over and over again.
