Case student develops booming on-line game


As if the World Wide Web doesn't offer enough ways to kill time, a Case Western Reserve University student has come up with another one—and it's a doozy.

John Tantalo, a junior computer science major in the Case School of Engineering, has put on line a game called "Planarity." The object of the game is to untangle a set of cris-crossing lines so that they no longer intersect. The game times players, and automatically moves them to the next level after they've successfully unraveled a puzzle. The game has an infinite number of levels—and the same capacity for causing frustration.

Tantalo developed the idea for Planarity along with his girlfriend Mary Radcliffe, mathematics major from Western Michigan University. Since going live in early July the game has become a big hit among bloggers and on-line gamers, receiving an average of 60,000 players a day and with links to more than 220 other Web sites. One blogger describes it as "an elegantly simple game with gratifying and addictive gameplay."
