Each game has nine entries, with no set time.

The entrance is the time and that a team assumes the attack and the defense.

The team that comes in as a defense first has the 9 players on the field, while the team that comes in as an attack counts, initially, with one.

All players on the team take the batting post, following a pre-established sequence.

When the batsman is unable to complete the four bases in one move, another player from your team enters as a batsman, so that he resumes from the base where he left off.
