LEVEL

 Our grades follow the Fontainebleau grading system. Fontainbleau ("Fb") grades increase in difficulty from 1 to 8. Every number is further broken down with letters a, b, c. And every letter can be supplemented with a "+", making it slightly harder. An example grade is "6b+".

In Fontainebleau, every colour represents a grade range. For example, black represents some of the hardest problems. Thus, at FLASHH, black means 8a to 8c+. All other colours have ranges too, with blue indicating boulder problems from 6a to 6c+. You can find every colour's respective grade range in our level table above.
