Summary: Smiley World Island Challenge is a simple game that is easy to learn and fun. Fans of Wii Play would like Smiley World. Serious gamers may not be interested in the title though. I give it 4.5 stars. Six games can be played in a versus mode. These games test your memory, hand eye coordination, and your ability to pick faces out of a crowd. The mini games allow you to complete a puzzle, and play old games like Memory and Simon Says.
