No balls in Cricket

There are front foot and back foot no balls and a whole range of other things such as:

• Throwing the ball rather than bowling
• Beamers
• Changing arms without notifying the umpire (who then notifies the striker).
• Too many bouncers in the over (the number varies according to the type of match)
• Bowling underarm (since 1982)

The full list is available from this link. Other interesting sidebars on this information include:

• International bowler no-balled for 'chucking'.
