Java random tests are messed up (they are separated by a digit), besides i think that some of them are wrong EG:

List myList = Arrays.asList(
"G1Yellow",
"C1Red",
"E1Yellow",
"B1Red",
"A1Yellow",
"E2Red",
"G2Yellow",
"B2Red",
"A2Yellow",
"C2Red",
"F1Yellow",
"F2Red",
"D1Yellow",
"A3Red",
"A4Yellow",
"A5Red",
"A6Yellow",
"B3Red",
"D2Yellow",
"G3Red",
"F3Yellow",
"F4Red",
"D3Yellow",
"G4Red",
"D4Yellow",
"D5Red",
"G5Yellow",
"C3Red",
"F5Yellow",
"E3Red",
"F6Yellow",
"D6Red",
"G6Yellow",
"E4Red",
"E5Yellow",
"C4Red",
"C5Yellow",
"B4Red",
"C6Yellow",
"B5Red",
"B6Yellow",
"E6Red"
);

The winner should be Yellow on D Column in the ""D4Yellow" movement, however is specting Red
