Ball Specifications (Dukes, Kookaburra, SG)
Different cricket balls are used in different countries — Dukes in England, Kookaburra in Australia/SA/NZ, and SG in India. Each behaves differently.
The Toss
Before every match, the two captains toss a coin to decide which team bats or bowls first. There have been proposals to eliminate the toss in Tests.
Reserve Days
ICC events can have reserve days for knockout matches to ensure results. Not available in bilateral series.
DRS Review Allocation
Teams get 2 unsuccessful reviews per innings in Tests (reset after 80 overs) and 1 in LOIs. Reviews are retained if the on-field decision is overturned.
Match Referee Powers
The ICC Match Referee oversees the match, handles Code of Conduct charges, approves concussion substitutes, and can impose fines and suspensions.
Pitch Preparation Standards
The ICC rates pitches after every international match. 'Poor' or 'unfit' ratings can result in demerit points for the venue.
Ground Size & Boundary Regulations
The ICC specifies minimum and maximum boundary distances for international cricket. The playing area must be as large as possible given the ground's constraints.
Test Matches
Test Match Playing Conditions
Test cricket is played over 5 days with unlimited overs per innings. Each team bats twice. 90 overs minimum per day.
Day-Night Test Cricket (Pink Ball)
Tests played under floodlights with a pink ball. Started in 2015 at Adelaide. Session timings adjusted — play starts later and continues into the evening.
Bad Light Rules
Umpires can offer batsmen the option to go off for bad light if conditions become dangerous. Modern floodlights have reduced bad light interruptions.
