```Hi,

You are already treating the "hand"s as random integers.

iL = hand (value) of left player
iR = hand (value) of right player

Get the value of (iL - iR).
Send above value to [sel -2 -1 0 1 2]

-2 .. Right player wins
-1 .. Left player wins
0 .. Even
1 .. Right player wins
2 .. Left players wins

There may be a smarter looking way without using [sel] but I think this
is as few as you can get with number of objects used.
