1. Multi-ball. All the same rules except two bowlers bowl at once, from either end. Run out can happen either either ball for either batsman. All completed runs just count as one as normal, but boundaries can be scored by both. Exception to the run out rule is if one batsman gets out. He can still run for his partner's shot, but has to leave the field of play once done.
2. Ball is fitted with a device that causes it to burst into flames at a predetermined but random time, ie different with each ball. Any player who refused to play once the ball is on fire will see the opposition awarded 50 runs. New ball is provided once the ball burns out.
3. Each batsman is allowed to pick one method of dismissal that doesn't apply to them at the beginning of an innings but it can't be run out (but can be stumped).
4. One hand and the whole team is out
5. Batsmen can't get out when playing a bad shot if they apologise
6. Weapons match. As well as the two batsmen, there's a third man who has possession of a foreign object of his choosing which he is allowed to chase fielders with throughout the innings
7. Double wicket match. Two wickets on the field. Both sides bat at the same time with nine fielders each. As soon as you're out you switch place with the next fielder in. To avoid confusion, one team bats with a white ball.
8. Ball-less match. The players pretend to have a ball but actually don't. The umpire has to guess where the ball would have pitched, whether he batsman would have hit it, whether the fielder would have caught it, etc.
9. Motorbike cricket. Same rules as normal except all players - bat, bowl, field - are on motorbikes. Played on normal bicycles at junior levels.
10. Batsmen use golf clubs instead of cricket bats.
11. Rugby ball replaces cricket ball
12. Ladder match. In order to take a wicket, you must retrieve the bails from the ceiling (only played indoors)
13. I quit match. Match goes on until one captain says I quit
