CountDown is a simple math game.
All you need to do is that just reach a target number by using 6 given random numbers. You can do all 4 basic math calculations as well.
For instance, let's say the target number is: 953 and you are given these 6 numbers: 1, 3, 4, 5, 10 and 85.
You can reach 953 by 1+4=5, 5+5=10, 10+85=95, 95x10=950, 950+3=953.
Of course, the real game may not be that easy. :)
---Big update: Soon, you will be able to multi-play.
