August 2017 - Solution
The first to get to nine balls without touching the rails was Oleg Vlasii:
O.....O .BW.BB. ..B.B.. .B.BBB. O.....O
(8,7) (11,7) (7,3) (11,5) (7,3) (11,7) (11,7) (4,7) (10,7)
He also created a solution in dedication of Maryam Mirzakhani (M):
O.....O BB...BB B.B.B.B B..W..B O.....O
(-3,7) (6,-7) (-6,7) (-2,1) (1,-3) (11,3) (11,-1) (5,-7) (-2,7) (2,-5)

Tyler Mullen sent us the solution with the highest number of balls (26):
OBBBB.O BBBWBBB BBBBB.B BBBBB.B OBBBB.O
(1,1) (-5,-3) (1,3) (-5,-1) (-1,-1) (5,-3) (5,3) (-1,3) (6,1) (-6,-1) (-4,-3) (-4,1) (4,1) (-6,1) (6,-1) (4,-3) (2,3) (4,3) (-5,-4) (1,4) (1,0) (5,2) (5,2) (-5,2) (1,4) (5,-4)
We also got a nice solution (with palindromic moves) from George Barnett:
O.BWB.O .B.B... ..B.... ...B... O..BBBO
(1,0) (-1,0) (1,1) (-1,1) (-1,-1) (-1,1) (1,1) (-1,0) (1,0)
