When the bell sounds to begin the first round, the bout will be considered official for betting purposes, regardless of the scheduled length or title.

If the scheduled length of the match is changed, all prior wagers on the number of rounds the bout will last will be graded as 'No Action'. 

Each round is three minutes in duration; a half-round is defined as ninety seconds. 

For wagering purposes, the disqualification of a boxer during a match will be counted as a knockout by his opponent. 

If the wagering offer on a match includes the draw as a third option and the match ends in a draw, wagers on the draw will be paid, while wagers on both fighters will be lost. If the wagering offer includes only the two boxers, with the draw either not offered or offered as a separate proposition, and the match ends in a draw, wagers on either fighter will be refunded. 

In situations not covered by the previous rules, the wagering decision announced by the Don Best Sports information service will be considered official and binding.
