Too easy!!
Easy Puzzle #5
The only losing move there is, is 1. Bc3. All other moves lead to a draw.
Heinzie is correct, though 1. Bg3 is definately the way to confirm it to your opponent right away! 
There is a difference between an easy puzzle and a bad puzzle. This one is outright bad, because there are eleven correct moves possible, of which only one will be counted "correct" by the application. No worries though, but next time try to come up with a position that has only one correct continuation.
