* Bowlers may bowl a maximum of only 4 overs per innings.

* Umpires may award 5-run penalty runs at their discretion if they believe either team is wasting time.

* The following fielding restrictions apply:
No more than 5 fielders can be on the leg side at any time.
During the first 6 overs, a maximum of 2 fielders can be outside the 30-yard circle.
After the first 6 overs, a maximum of 5 fielders can be outside the fielding circle.

* Should a bowler deliver a no ball by overstepping the popping crease, it costs 2 runs and his next delivery is designated a free-hit, from which the batsman can only be dismissed through a run out.

* If the fielding team do not start to bowl their 20th over within 75 minutes, the batting side is credited an extra 6 runs for every whole over bowled after the 75 minute mark; the umpire may add more time to this, if he considers the batting team is wasting time.

* If the match ends with the scores tied and there must be a winner, the tie is broken with a bowl-out (similar to a penalty shoot-out in football), with 5 bowlers from each side delivering 2 balls each at an unguarded wicket. If the number of wickets is equal after the first 10 balls per side, the bowling continues and is decided by sudden death.
