Good to Know


Everyday of the championship, three new levels will be added to the Phÿs championship app. You'll have up to three attempts per level per day to complete each of the available levels. The goal is to solve all the levels with the fewest throws.

The best score obtained for each level during those three days will be the one used for your total and final score.

Attempts are not cumulative: if you do not use all of them on the day, they will be lost.

The levels are the same for all age categories.

You can have a different team in every categories: each category will be allowed three attempts per level per day.



All participants consent to respect these rules:

  • Participants need to keep a distance of 3 feet from the wall.
  • There is no limit to the number of players on a team: be wise!
  • You are allowed 3 attempts per level, per day.
