Exactly what the name implied celebrities participate in a regulation game of bowling.

Two celebrities vs two celebrities in "best ball" competition. Both players on one team roll first balls. From the result they accept the best "leave"--2 pins left on one lane better than 5 left on other. The player who did NOT bowl the "best leave" then rolls for the spare. If either player rolls a strike on their first ball, that's the best the team can score in a given frame. Each epsiode is a modified 10-frame bowling game, with some frames bowled off-camera, as time allows.—Anonymous
