In 1993, Joel Feinstein found one of perfect plays for Othello (Reversi) with board size of 2n×2n (n = 2,3) , which showed that the second player(White) is the winner, respectively. We have been analyzing Othello with a board size of 4×2n (n = 3,4,…) since 2015. As results, we found one of perfect plays for each on the 4×2n (n = 3,4,5) boards, which showed that the first player (Black) is the winner, respectively. Recently, we have finished the analysis of the 4×12 board. In this paper, we will introduce the analysis results of 4×12 board Othello and summarize the results that have been found so far.
