It was literally all fun and games for Mary-Kate Olsen and Ashley Olsen‘s big birthday weekend.

The twins, who turned 29 on Saturday, threw a casual, outdoor game-themed soiree for their big day.

Dubbed the Olsen Olympics, guests were divided into two teams – red Team Mary-Kate and blue Team Ashley. Revelers shared photos of the epic games via Instagram, showing off the outdoor set up – which included a dunk tank and a colorful maze complete with tires and cones.

The 2015 CFDA Womenswear Designer of the Year winners went head-to-head, with several friends taking on the role of camp counselors. Team Ashley came out on top, celebrating the win with sparkler-like fireworks.

“I swear no one chose favorites, they were picked out of a hat #fairgame #olsenolympics,” one friend wrote on Instagram.

Seemingly missing from the festivities? Mary-Kate’s much older fiancé Olivier Sarkozy, 46. The French banker got engaged to the actress in March 2014.

The famous sisters recently announced they wouldn’t be joining the rest of their Full House castmates in the upcoming Netlfix reboot, Fuller House.
