In first-class cricket matches, each team has two-innings, ten wickets to lose in each inning and no limit on the number of overs in which to use those ten wickets. However, there is typically a four or five day limit on the length of the match. The aim is to score as many runs as possible and a team is declared the winner if they have scored more runs than the other team over both innings' provided that their opposition has lost all their wickets. Thus if one team has scored less runs but has not lost all their wickets when time runs out, the match is declared a draw.
A one-day cricket match consists of one innings per team with 10 wickets to lose and a 50-over limit on the innings. So unlike first-class cricket, a one-day cricket match must have a winner unless each team's score is the same at the end of the match, in which case the result is a tie.
