What is T-20?
'T-20' is short from 'twenty 20', and it represents a modern variation of cricket game. Basically, it is still a cricket as you play it with traditional equipment, on a normal cricket stadium. It's just that the rules are slightly changed. Rules are tuned to make the game more dynamic and more interesting. T20 has definitely contributed to the further popularization of cricket around the world. I decided not to enlist single one rule, because things are simplified in cricket flash games anyways, so it really doesn't matter, just follow the in-game instructions and you should be fine.
What is Super Over (Eliminator)
It's a shortened version of a match. It's played 10 minutes after the t20 match if it is finished with the tied score. Since 2012, Standard Twenty20 playing conditions enforces the official super-over rules. Because super over decides the winner, it is also called the "Eliminator".
