A lot or a little?
Parents need to know that Mystery Coast: Treasure Hunt is an interactive adventure app for iOS devices. The game is free to use, but the app limits the amount of time gamers can play it unless they buy gems or watch an ad. The kid-friendly content includes brief videos with actors portraying characters who offer information. Instructions are provided to walk players through each new aspect of the experience, making it easy to follow. They don't get to do too much -- kids spend a lot of time cleaning items from dives -- but they have to do it well to continue playing, and it could spark an interest in archeology or the ocean.
