Caution: Puzzle Solver Crossing

Keep an eye out for groups of people doing weird things all over the City on Saturday. No, no. Different weird things.

The company behind Perplex City has organized a major live event here in San Francisco. Perplex City is a collectible card game with a twist: Each card is a puzzle and a clue to a hidden treasure worth $200,000. The puzzles range from yawningly easy to clever and intriguing to annoyingly difficult.

The live event here in San Francisco will feature puzzles that lead teams around the City in a sprawling scavenger hunt, and the company keeps touting their innovative use of real-time RFID technology. We don't know all the details yet, but this SFist will be in the hunt and we'll provide a full report early next week. Winners will get points that push them up on the all-important leaderboard.
