A snooker type of game is called volunteer in which a player is allowed, after potting a
red ball legally continue his turn and play on a nominated color ball then on . there is no
limit to the number of volunteered colors the player could pot, although if the same
colored ball is potted three times in a row successfully from the same spot then it remains down and
can not be put back on the table until the next stroke takes place.
A player can nominate a color ball only if he has pot a red ball legally . the game comes to
an end when all the balls are pocketed.
In its Persian style, reds could be reduced to ten, six or even three for a faster frame and you
are not allowed to snooker your opponent(s) by a free-ball nor a ball-on.
When ever a player fails to pot a volunteered color then it is deemed a foul stroke. All the other
applied rules are same as standard billiard rules in general and snooker games in particular.
this came stayed common in Iran for past 50 years.
