Big RR is turn based. Given the fact that Triad finished first (and start first), we calculate based on triad's finished turn.
Triad finished. 0 turns (base)
Jot finished 1 turn after that. (2 turns, but since Triad started first, it gets counted as 1)
Chelsea finished 1 turn after that. (2 turns, but since Triad started first, it gets counted as 1)
KILLER would have finish on 2nd turn. (Chelsea shouldn't have plop his worm). (3 turns, but since Triad started first, it gets counted as 2)
0 + 2 = 1 + 1
It's a draw.
