He can do way more.Two very easy things can be done so olympiad is more enjoyable and not as predictable
1st hide the names of the opponent (e.g make everyone's name displayed as "olympiad")
2nd hide the points from the olympiad manager but keep the rankings(e.g from 1st player55 75 pts,2nd player81 45 pts to just 1st player55 2nd player81)
