McHENRY — Students at McHenry Middle School may soon become Guinness World Record holders.
The school said 815 students participated Thursday in simultaneously playing Ninja. The unofficial record for the largest game of Ninja is 430 people.
The popular playground game is played by taking turns swiping at the opponent's hands. Players take turns with offensive moves toward their opponents hands and must freeze once their move is finished. Defending players may dodge if they think they will be hit, and must freeze once the attack is finished. Once a player is hit, he's out.
The game started with 79 smaller games going at once. As players were eliminated, it was narrowed down to one final winner.
McHenry Middle School physical education teacher Brian Schweitzer said students play the game in PE classes and during wrestling and track meets.
"They're running it themselves when they get out there. We're just guiding them about it." Schweitzer said.
"That's what's fun about it, seeing them get excited about an activity or something they're doing."
Guinness has to validate the game before the school can become world record holders.
