  • Ease of use4
    Very easy to play. Simply look at the number you need to match and tap the balls with numbers on them that add up to that first number. It would be nice if there were a setting for younger kids to slow down the dropping balls or limit the range of numbers used.

    Some privacy concerns. Users can opt in to OpenFeint, an interactive network that allows users to upload real avatar photos, post on message boards, connect with Facebook friends or Twitter followers, and access live chat with strangers. Some safety concerns. If users opt in to OpenFeint they can choose to share their personal information with strangers. Kids can play Mathris without enabling OpenFeint.

What parents need to know

Parents need to know that Mathris is a fun, arcade-style game kids can play to practice rapid-fire addition. Players tap on falling balls that add up to a target number in order to rack up enough points to move onto the next level before the screen fills up with balls. Mathris is OpenFeint enabled, but players don't have to participate in OpenFeint to play the game, and Common Sense Media doesn't recommend kids or tweens use OpenFeint without adult supervision (see Privacy & Safety concerns). Higher levels of play require an in-app purchase of $.99.
