Play Process

Beginning:

A player of the offense team must run toward the disc after the first throw is made. If he is there, he gets the disk by putting it on top of his head (i.e. coin).

At least one other fellow players should make now his steps in such a way that he stands freely in one of the possible throwing directions. Because throwing in only one possible direction can become relatively simply bocked by a marker, it is recommended to position always two or three possible catchers in different throwing directions.

Play:

As already said, the sequence of running and throwing always looks the same during the game:

The 3 offense player without the disc may be shifted over up to 4 fields. They should place themselves in such a way that they can catch the disk. Thus they must stand somehow in a legal throwing direction, preferably with a possible gain of space. For that purpose it is tactically intelligent to occupy also important defense positions. Players can place themselves also between several defenders, who then stand and remain there and also block. Only if they move somehow in the play process, then they must depart from this aggressor.
In the next step the 4 defense players are shifted over up to 4 fields. They are trying to mark all possible throwing directions, so that a turn occurs. An offense player may be covered however by maximally only one defense player, i.e. no matter what, only one marker may be located in the neighbouring 8 fields of a player of the other team(!). this makes it for the defense particularly tricky to force a turn.
At last the offense player with the disk throws the disc to a fellow player in one of the permitted throwing directions. The catcher gets the disc and the game ist continued as under the first point.

Tactics (example):

You will notice very fast that most passes are made usually over a distance of only two fields, because throws over further distances can be prevented too easily by the defense. On the other side, the defense can easily block important, potential catcher positons in an "error free" play, so that one seems not to make any progress by playing towards the endzone. Such a situation is shown in fig. 1 +2. The pass to the free catcher produces a situation, in which a throw toward endzone can be prevented again (see arrow in fig. 2). A resulting replay or a similar ineffective throw would be the consequence.

But the Defense can be surprised easily by a variant: E.g. if two players place themselves side by side as in fig. 3+4, both can potentially catch the disc in the next step. In this case all important fields (arrows in fig. 5) cannot be covered by the defense, so that according to this principle in the process further positions can be taken towards the endzone.
There are similar tricks like throwing the disc to a back player etc. Try to find these tricks e.g. by playing with care or by playing alone.
