FX Games for everyone.

We want you to own the sport you love. Our FX Games structure makes it easy for game makers to create events that appeal to the many and the few.

How to make your own FX Games:

  1. Choose your level ‘Sans’ or ‘Olympic’
  2. Customise your components
  3. Play!


The athlete or team with the most points at the end of all stages will be declared the FX Games winner.

Only 8 competitors advance to the finals. Places are awarded to the top 8 competitors with the highest cumulative points from the qualifying stages. Points are awarded in the same way as the qualification stage and added to make the final overal score. In the event of a tie, the fastest final Arena finisher wins.

All competitors complete three (FX Olympic) or two (FX Sans) stages. Points are awarded based on performance as follows:

  • Trail & Arena: individual events are completed for time. The top 10 fastest finishing times per individual event will be awarded points from 10 – 1 in ascending order (e.g. 10 points to first place, 9 points to second place… 1 point to 10th place).
  • Ring: 10 points to the winner, 9-7 points to the loser (in accordance with England Boxing Rules, page 33).

About ISFX.

We are the international sports federation for FX.

ISFX is the international sports federation responsible for administering FX at a world level, including the FX World Games and international ISFX Jara Cup League. We were created in June 2020 as a first step in the process to making FX an Olympic sport. We partner with governmental and non-governmental organisations to ensure FX remains clean, accessible and inclusive at all levels of the sport.


We believe FX has all the makings of a modern Olympic sport – compelling athleticism and global popularity. Like skateboarding, surfing and BMX freestyle, our purpose is to legitimise FX as a sport and achieve Olympic status.


Our brand mark, Icelandic rune symbol ‘Jara’ (harvest), symbolises the training intensity and commitment athletes make in preparation for competition. Our motto, ‘Compete against yourself first’, recognises the personal progression and practice of the sport.

FX World Games.

Winning the The FX World Games is the ultimate accolade for any FX athlete and FX team. The FX World Games are held only once every two years. The inaugural FX World Games is rescheduled for November 2021.

ISFX Jara Cup League.

The ISFX Jara Cup League is the annual international FX league for athletes of all abilities. It is used to seed players in competition to ensure early rounds are fair and balanced. The league runs from November to July.

FX is a 100% grassroots sport.

FX is the ultimate strength and conditioning sport designed to be enjoyed anywhere by people of all abilities (intelligence and physical). Many of the moves are functional and can be performed based on the individual needs of each FX athlete.

The big 5.

FX combines 5 of the toughest Olympic sports into 1. These sports are: lifting, gymnastics, boxing, running and swimming.

FX in competition.

You do not have to compete to enjoy FX, but sportsmanship is the defining quality of FX athletes and there’s no better place to show this off than in competition. Where possible we prefer FX Games to be mixed ability. There are two categories of FX Games: Olympic and Sans.

  • FX Olympic: triple-stage event includes combat sports (trail + ring + arena)
  • FX Sans: duo-stage stage event excludes combat sports (trail + arena)


FX is a community-based sport and we are committed to maintain that inclusivity as it advances to Olympic status. We encourage all FX athletes, businesses, brands and fans to get involved in shaping the values, standards and management of the sport. – all ISFX members have a voice.

As a new international sports federation we are presently in the process of creating our Governance Handbook. In accordance with our Articles of Association, the first draft will be ready for review within 90 days of incorporation (i.e. before Thursday, 17 September).

Strength and Conditioning encompasses the entire physical development of the athlete and what is required to allow them to be the best physical version of themselves.
