The way this checks the if someone won is:
First: it checks if the btnEmpty[x] is not equal to an empty string- x being the array number

Secong: it checks if btnEmpty[x] is equal to btnEmpty[y]- x being winCombo[each set][the first number]
y being winCombo[each set the same as x][the second number] (So basically checks if the first and
second number in each set is equal to each other)
Third: it checks if btnEmtpy[y] is eual to btnEmpty[z]- y being the same y as last time and z being
winCombo[each set as y][the third number][Find More Java Codes at www.sumikuma.tk]
Conclusion: So basically it checks if it is equal to the btnEmpty is equal to each set of numbers

MATCH REPORT: BNI INDONESIA ALL-STARS 1 CHELSEA 8

By The Weird Writer
MATCH REPORT: BNI INDONESIA ALL-STARS 1 CHELSEA 8 Summary  An enormous and vociferous crowd of Chelsea fans came to see the team on our Indonesian debut and they were rewarded with goals galore, including some quality strikes, as the Asia tour ended in style. The Chelsea goals were split equally between the halves - Eden Hazard, Ramires, Demba Ba and John Terry the scorers before half-time, with Ramires again finding the net after the interval and Romelu Lukaku scoring two as well. Bertrand Traore added to his goal in Malaysia shortly after coming on at half-time. The sole goal from the Indonesian All-Stars was an own-goal, conceded when we were already 8-0 up. Gary Cahillwas the one Chelsea man to play 90 minutes. Chelsea  (4-3-3): Blackman (Schwarzer h-t); Wallace (Ivanovic h-t), Cahill, Terry (c) (Kalas h-t), Bertrand (Cole h-t);Ramires (Feruz 59), Chalobah (Essien h-t), Van Ginkel (McEachran 59); Moses (Traore h-t), Ba (Lukaku h-t), Hazard (Piazon 59). Scorers
