How does it work?

Your Number will be between 40-1

  • Beginners start at 40
  • Pro players will be closer to 1

How often will my Number change?

Our algorithm will calculate your Number on a weekly basis. Getting out on court is the key to seeing yours change.

What is Game zONe?

Our Game zONe identifies a range of potential opponents whose Numbers are close to yours on the scale.

  • Game zONe will find evenly-matched opponents wherever you are, to ensure the best possible experience on court
  • Our industry-leading algorithm analyses player performance data and millions of match results.

Don’t forget, as your Number changes, your Game zONe will change too, so be sure to check back regularly to find new opponents to play.
