The conditional probabilities are likelihoods, based on (r/n) = (realizations/no. of observations). 

Moves right at x1 ending with payoff [35, 70] can be inferred from the left and right branch denominators shown in these entries—e.g., 116 of 120 moved right or left in repetition blocks 1–5, implying that four pairs ended at [35, 70]. 

Moves ending with payoffs [0, 0] at these nodes can be inferred from these entries—e.g., if 0 of 1 end at [15, 30], then 1 of 1 ended at [0, 0].
