Warren Buffett is famously known to play bridge.
Bridge is a four-player partnership card game in which players bid to determine the contract and then try to win tricks. It combines probability, memory, communication, and strategic inference—qualities that help explain why Buffett has described it as an especially engaging mental challenge.
Buffett has played bridge for many years, including online and with notable partners. He is particularly associated with Bill Gates, and the two have played together at Berkshire Hathaway gatherings. Buffett has also been reported to spend roughly 12 hours a week playing the game.
Bridge is not the same as poker, gin rummy, or canasta. Poker emphasizes wagering and concealed information among individual players, whereas bridge is a partnership game built around bidding, shared conventions, and trick-taking. Buffett’s bridge habit is a personal pastime, not part of Berkshire Hathaway’s investment strategy.
