The eight qualifers have been divided into two groups of four -- one hosted in India and one in Sri Lanka.
No points are carried over so each team starts the Super Eights with a clean sheet.
The winner of each match receives two points, the loser gets none.
If a minimum of five overs per side is not possible because of bad weather in any match, then that match will be declared a no result with each side getting one point.
Any match that finishes in a tie will see a super over played. If the super over is also a tie, subsequent super overs will ensue until there is a winner.
The top two from each group will advance to the semi-finals on March 4 and 5.
The T20 World Cup final is on March 8.
