'Power Surge', 'X-factor Player' and 'Bash Boost' are the three new rules that have been introduced by Cricket Australia for the tenth edition of the Big Bash League (BBL) which starts December 10.

The 'Power Surge' will consist of a two-over period where the fielding side is allowed only two fielders outside the inner ring. The batting side can take it at any given time from the 11th over of the innings onwards. Meanwhile, the powerplay at the start of the innings has been reduced to four overs.
The 'X-Factor player', named as either the 12th or 13th player on the team sheet, can come into the game at the 10th over of the first innings and replace any player who is yet to bat or bowled no more than one over.

The 'Bash Boost' is a bonus point which will be given midway through the second innings. The side that is chasing down the target will be awarded with the bonus point, "if they're above the equivalent 10-over score of their opposition". However, if they're trailing, the fielding side will receive the point. A team can now score four points every game as the points awarded for a win in general has been increased to three points from two previously.
