Pool3 [logically also known as Pool–Three]. The rules don't particularly differ from regular European pool practice.
Pool3 is meant for three players.
Opening sequence : The first player catching full or half, here & now called [A], continues on full or half as long as his catch goes.
After a mistake of [A] the second player, here & now called [B], takes over. If [A] had full, than [B] takes half, or vice versa.
After a mistake of [B] the third player, here & now called [C], takes over. If [A] had full, then consequently [B] took half (or vice versa), and [C] continues on full.
After a mistake of [C] player [A] switches to half. Hereafter [B], who entered on half, switches to full, and [C], who entered on full, switches to half, and so on :
[A] enters on full – [B] enters on half
[C] enters on full – [A] switches to half
[B] switches to full – [C] switches to half
[A] switches to full, and so on
So all players, [A], [B] and [C], consecutively switch, as it goes, from half to full, each of three having both other players as opponent.
If [A] makes a wrong touch, or any similar mistake offering twice on white to his opponent, [B] takes advantage of it. If [B] makes a wrong touch, [C] takes advantage of it, and so on.
Finally getting to the black one, or Eightball, the sequence of Three, is as above. For instance, if [B] gets to the black one first, he may finish and win the game; if he fails on black, [C] takes to the other series, full or half, and after that [A] enters on the black one, leaving, if he fails on black too, the remaining series to [B], and so on.
A fatal curve on the Eightball [e.g. finishing the black one where it shouldn't be finished) makes out. Then both other players go on as regular. [ ]
