blaze didnt explain very well xD
What we did was:
The ts hid, and cts tried to fnd them and hit them with the pistol.
If the cts couldnt find and hit them before round end, the ts won.
the teams would switch roles every round and so on.
Pretty much it
EDIT: The reward could be like 50 extra health next round... or something ;P. And it would reward the whole team of course
