soo... basically it misses a random number generator? I'm not familiar with java but is it really that hard to add a random number generator to it? you could then link a certain number to winning while the others are losing numbers right or am I babbling impossible nonsense now? :S
that way the random number generator would randomly generate a number (o-9 for example) and only if the number was correct(0 for example) it would give you a winning result :S
