1. 25 overs per innings
2. Fielding circle - max 5 fielders outside the circle at any time
3. max 5 overs per bowler
4. Retire at 50
5. Free hit after a No Ball (with no changes to the field)
6. Any delivery passing the leg stump without contact is a wide
7. Six legitimate deliveries to be bowled per over - wides and No Balls penalised with 1 run
