The Real MIT Blackjack Team: How Math Students Beat the Casinos

In 1979 an MIT computer science student named J.P. Massar used a Lincoln Lab mainframe to test a claim his friends had brought back from a course called How to Gamble if You Must: that blackjack could be beaten. The math held. What followed was two decades of organized card counting that took millions from casinos in Atlantic City, Las Vegas, and beyond, and it looked very little like the book Bringing Down the House or the movie 21.

This episode tells the factual version. The early players were talented and disorganized until Massar met Bill Kaplan, a Harvard graduate who had already earned a 35 fold return running his own team in Las Vegas. Kaplan imposed one counting system, tracking sheets for every session, and a brutal checkout test, and the team became a business. By 1992 it was a million dollar limited partnership called Strategic Investments, fielding spotters, controllers, and big players across the world until a stack of MIT yearbooks gave them away.

• A New Jersey Casino Control Commission ruling barred Atlantic City casinos from banning card counters, which is why the students started there instead of Las Vegas.
• A professional gambler named Dave fronted $5,000 after seeing a flyer for the blackjack course, and the group turned it into $20,000 between late December 1979 and May 1980.
• The first formal bank launched on August 1, 1980, with $89,000 and ten players. It more than doubled in ten weeks, and players averaged over $80 an hour.
• New recruits carried cash as mules and had to play perfectly through eight full six deck shoes before they were allowed on a casino floor.
• Griffin Investigations noticed that many barred players had addresses near Cambridge, then matched surveillance images to MIT yearbook photos. Strategic Investments dissolved on December 31, 1993.
