Some of the sports that are currently held at the World Games are acrobatic gymnastics, ultimate, orienteering, body building, powerlifting, finswimming, squash, billiards, water skiing, and dance sport. The sports that are included in the World Games are limited by the facilities available in the host city; no new facilities may be constructed for the games. Up to now between 25 and 35 sports were included in the programme of The World Games. The IWGA, in coordination with the host city, can invite some sport to participate in the "invitational" programme. No official World Games medals are awarded to invitational sports.
