The best one

Im pretty good at othello game and other two free ones are east to beat which make them not worth keeping.
This paid one is very competitive. At master level, I won one time out of 5 matches so far.
If you only want an othello game for anoccasional entertainmant, get the free ones.
This paid one has better graphic movement, sound, and usuful options that make 2 bucks worth paying.
No bugs for me so far.
