A legally potted ball entitles the striker to continue at the table until he fails to legally pot a ball.

2. On all shots, the striker must comply with the appropriate requirements of Rules of Play 5 and 6. It is not necessary to cause the cue ball or an object ball to contact a cushion or drop in a pocket after the cue ball has contacted a legal object ball (ball on). Failure to contact a legal object ball first is a foul.

3. As long as reds are on the table, the incoming striker (player taking his first stroke of an inning) always has a red as his legal object ball (ball on).

4. Any red balls potted on a legal shot are legally potted balls; the striker need not call any particular red ball(s), pocket(s) or details of how the pot will be played.

5. When the striker has a red ball as his "ball on" (legal object ball), he must cause the cue ball's first contact to be with a red ball. Failure to do so is a foul (See Penalties For Fouls)

6. After the striker has scored a red ball initially, his next legal object is a color, and as long as reds remain on the table he must alternate his play between reds and colors (though within each group he may play a ball of his choice). When reds remain on the table and a color is his object, the striker must (a) designate prior to stroking which color ball is his object (that specific color is then his "ball on"), and (b) cause the cue ball's first contact with a ball to be with that colored ball. If the striker fails to meet these requirements, it is a foul (See Penalties For Fouls).

7. If the striker's ball on is a red, and he pots a color, it is a foul.

8. If the striker's ball on is a color, and he pots any other ball, it is a foul.

9. Jump shots are illegal in International Snooker. It is a foul if the striker intentionally causes the cue ball to jump (rise from the bed of the table) by any means, if the jump is an effort to clear an obstructing ball.
