Twenty20 is cricket's shortest professional format: 20 overs per side, matches done in about three hours. It rewards bold batting, clever bowling variations, and razor-sharp fielding. Here is how it works.
The basic rules
Each team bats once for a maximum of 20 overs (120 legal balls). The team with more runs wins; if scores are level, a Super Over — one extra over per side — decides it. Bowlers are limited to 4 overs each, so captains must use at least five bowlers.
Two fielding restrictions shape the whole game. During the powerplay (the first 6 overs), only two fielders are allowed outside the 30-yard circle, which encourages aggressive batting. After that, up to five fielders can patrol the boundary.
The three phases of an innings
Powerplay (overs 1–6): Openers attack with the field up. Losing early wickets here can cripple an innings; surviving it with wickets in hand sets up a big total.
Middle overs (7–15): Spinners and slower bowlers try to squeeze the scoring. Smart teams rotate strike and target one weak bowler per over rather than swinging at everything.
Death overs (16–20): Anything goes. Batters premeditate ramps and scoops; bowlers respond with yorkers, wide lines, and slower-ball variations. Matches are won and lost here — a 60-run final three overs can flip a game.
Bowling strategy
With only 24 balls per bowler, there is nowhere to hide. The best T20 bowlers master variations: the slower ball, the knuckleball, wide yorkers, and deceptive changes of pace. Death bowling — defending runs at the end — is a specialist art, and match-ups (a spinner against a batter who struggles against spin, for example) drive captaincy decisions.
Why it matters
T20's pace has changed all of cricket: batters play shots once considered impossible, fielding standards have soared, and franchise leagues now span the globe. Whether you are watching your first match or your thousandth, remember the golden rule of T20 — the game is never over until the last ball.
