Problem Statement

Morteza and Amir Reza play the following game. First each of them independently roll a dice 100100 times in a row to construct a 100100-digit number with digits 1,2,3,4,5,61,2,3,4,5,6 then they simultaneously shout a number from 11 to 100100 and write down the corresponding digit to the number other person shouted in their 100100 digit number. If both of the players write down 66 they both win otherwise they both loose. Do they have a strategy with wining chance more than 136\frac{1}{36}?
