Rule variations

The following rule modifications to the T10 format are in effect in ISPL matches: [18] [19] [20]
- Powerplay: There is a mandatory powerplay for the first two overs of each innings, and then the batting team may elect to take a one-over 'batting powerplay' between the third and ninth over. During the mandatory powerplay, only two fielders are allowed outside the 30-yard circle, while three fielders are allowed outside of the circle in the batting powerplay.
- Tip-Top Toss: Instead of a coin toss, the following procedure is used: initially, the two team captains stand opposite each other, and then walk in a straight line towards each other, with each step required to be from heel-to-toe. The team captain who is able to step on top of the other team captain's foot wins the toss. [21] [19]
- 9 Street Runs: If the ball is struck out of the field and lands among the spectating audience, nine runs are scored rather than six.
- 50-50 Over: The bowling team's captain has to pick a minimum of five bowlers from his playing XI, any one of whom can be challenged by the batting team to bowl one '50-50 Over'. [18] In the 50-50 over, the batting team states the minimum number of runs they believe they will score in the next over; the number chosen must be at least 16. If the batting team successfully scores this minimum number of runs, 150% of the runs that they scored in the 50-50 Over will be added to their final match score. (e.g. scoring 18 runs in the over results in a total of 27 runs being added to the final score of the batting team as a result of the over.) However, if the batting team fails, only 50% of the runs scored during the 50-50 Over are added to their final match score. [20] [19]
- Tape-Ball Over: While the majority of the match is played with a tennis ball, two overs in each inning have to be bowled with a tape ball. [19]
- Playing XI: Each squad in the ISPL can have a maximum of 16 players, including at least one U-19 player and one player from each of the zones (North, South, East, West and Central).
