# One-Ball Handicapping

The purpose of the One-Ball handicapping system is to allow AC and GC players to play One-Ball on a level playing field. It was researched and developed by Kevin Carter (organiser of The National Charity One-Ball competition), and was formally adopted by Croquet England in 2018.

These One-Ball handicap rules conform to the Laws as modified by the Tournament Regulations as follows:

- First, AC handicaps below 2 are adjusted as follows:
AC Handicap 1½ 1 ½ 0 -½ -1 -1½ -2 -2½ -3 One-Ball Handicap 1 0 -1 -2 -3 -4 -5 -6 -7 -8 - Then take the lowest of:
- the adjusted AC handicap
- if GC handicap above zero: 2.5 x GC handicap, otherwise GC handicap
- 20

- The number of bisques given is one-third of the difference between the players' handicaps with any fraction rounded to the nearest half-bisque

Players may wish to use the online Handicap Calculator, however, as this is not maintained by Croquet England, if there is a discrepancy with the calculation using the method described in the latest GC Rules, AC Laws and Tournament Regulations, the Croquet England method is paramount.
