The game shall consist of two halves of 20 minutes each an interval of 10 minutes between halves.
Note - If local conditions warrant it, the organizers may increase this interval to 15 minutes. This decision must be made known to all concerned before the beginning of the game.

The game shall be started by the Referee who shall toss the ball up for a centre jump between two opponents in the centre circle; the same procedure shall be followed at the beginning of the second half and, eventually, of each extra period.
The visiting team shall have choice of baskets in the first half, on neutral courts, teams shall toss for baskets. For the second half teams shall change baskets.

A jump-ball takes place when the Official tosses the ball between tow opposing players.
During a jump ball the two jumpers shall stand with their feet inside that ha1f of the circle which is nearer to their own baskets, with one foot near the сentre of the line that is between them. An Official shall then toss the ball upward (vertically) in a plane at right angles to the side lines between the jumpers, to a height greater than either of them can reach by jumping and so that it will drop between them. The ball must be tapped by one or both of the jumpers after it reaches its highest point. If it touches the floor without being tapped by at least one of the jumpers, the Official shall put the ball in play again the same place.
Neither jumper shall tap the ball before it reaches its highest point, nor leave their positions until the ball has been tapped. Either jumper may tap the ball twice only. After the second tap by a jumper he shall not touch the ball again until it has touched one of the eight non-jumpers, the floor, the basket or the backboard. Under this provision four taps are possible, two by each jumper. When a jump-ball takes place the eight non-jumpers shall remain outside the circle (cylinder) until the ball has been tapped. Team mates may not occupy adjacent positions around the circle if an opponent desires one of the positions.
During a jump-ball the Officials shall see that the other players are in such positions that they do not interfere with the jumpers.
a player shall not violate provisions governing jump-ball. If, before the ball is tapped, a jumper leaves the jumping position or if a non-jumper enters the circle (cylinder), the Officials are authorized to give the violation arm signal but to withhold the whistle, to give opportunity for the opposing jumper to tap the ball into the basket, or to tap it in such a way that one of his team mates is first to touch the ball. If either of these occurs, the violation is disregarded. If both teams violate the jumping rule, or if the Official makes a bad toss, the toss sha1l be repeated.
