looks like I did mutate the input, it is working now, not getting the issues anymore with the draw tests, thanks!

anyone else having problems with the ruby random tests? I manually tested a couple I got wrong but even drawing it out on a grid, it should have passed. Issues seem to be with the Draw tests.

["B_Red", "D_Yellow", "D_Red", "A_Yellow", "F_Red", "C_Yellow", "F_Red", "A_Yellow", "E_Red", "F_Yellow", "C_Red", "F_Yellow", "C_Red", "E_Yellow", "E_Red", "A_Yellow", "E_Red", "B_Yellow", "B_Red", "C_Yellow", "D_Red", "E_Yellow", "B_Red", "E_Yellow"]

-> expected draw, but the winning move is horizontal red

["D_Red", "F_Yellow", "A_Red", "G_Yellow", "B_Red", "D_Yellow", "C_Red", "D_Yellow", "A_Red", "B_Yellow", "E_Red", "D_Yellow", "C_Red", "G_Yellow", "B_Red", "D_Yellow", "G_Red", "B_Yellow", "F_Red", "A_Yellow", "G_Red", "E_Yellow", "F_Red", "A_Yellow", "C_Red", "F_Yellow", "F_Red", "D_Yellow"]
#-> expected draw, yellow actually wins bottom horizontal

["F_Red", "D_Yellow", "G_Red", "A_Yellow", "D_Red", "C_Yellow", "F_Red", "B_Yellow", "G_Red", "A_Yellow", "D_Red", "E_Yellow", "D_Red", "A_Yellow", "C_Red", "A_Yellow", "G_Red", "E_Yellow", "A_Red", "D_Yellow", "D_Red"]
#-> expected draw, yellow actually wins bottom horizontal

["D_Red", "F_Yellow", "B_Red", "C_Yellow", "D_Red", "C_Yellow", "D_Red", "E_Yellow", "G_Red", "B_Yellow", "G_Red", "C_Yellow", "D_Red", "E_Yellow", "F_Red", "F_Yellow", "B_Red", "D_Yellow", "A_Red", "B_Yellow", "D_Red"]
#-> expected draw, red actually wins vertically in D
