Here, TSN has you covered on all the rule differences between the IPL and T20 World Cup.

Why does T20 World Cup not have 2 bouncers per over? What are the differences in rules between IPL and ICC World T20?

While most of the rules between the IPL and international cricket are common, there have been a few tweaks during the domestic competition. One was made ahead of this season's tournament, when it was decided that fast bowlers would be allowed to bowl two bouncers per over, instead of the usual one.

However, this rule does not apply to international cricket or the T20 World Cup. Bowlers are still only permitted one bouncer per over, and both bowlers and batters coming off a two-month long IPL season will need to readjust for the global competition.

Another important difference between the IPL and the T20 World Cup is the Impact Sub rule. IPL teams are allowed to substitute one player for another at any point in the match, but this rule is not in effect in international cricket. In addition, the use of the DRS (Decision Review System) to refer wide or no-ball calls is not allowed in international cricket. Only decisions relating to dismissals can be reviewed by players.

Part and parcel of the IPL has been the standard two and a half minutes 'strategic time-outs' which happen twice per innings. This is not a feature in international cricket. Instead, there is just one drinks break per innings, which will be taken by the umpires roughly around the halfway stage.
