I know its a little long, but you can easily see how to use the cheat engine.\rbrStart a wave and collect one coin. NOTE: one coin equals 3, so when you add the value to the cheat engine put 3 for one coin and 6 for the second coin and so on. UNLESS you have the double coin for life then it would be 6 to one coin. After the wave it will give you all the coins or gems.
