The Pentamind World Championship was one of the Mind Sports Olympiad’s original events. It is a unique meta-event, which celebrates the best all round games player in the world. Any event at Mind Sports Olympiad can count towards that year’s Pentamind, and the player with the highest top five scores is crowned the Pentamind World Champion.

The Pentamind scores must use games from different categories (e.g. one chess variant, scrabble, go, poker and backgammon; however, a player cannot use two backgammon scores or two chess scores toward the Pentamind; they must also incorporate at least two double session events). The Pentamind champion is the player with the highest numerical score in “pentamind points” from 5 valid events. This is calculated using the formula (n/(n+1)) x 100 x (n – p) / (n – 1), where n is the number of players and p is the player’s position in an event. The position is the position before tie-breaks and any split positions are shared amongst all of the tied players.
In the event of a tie for the Pentamind World Championship, the next Pentamind score (i.e. the 6th best result) will be used as a tiebreak; the secondary tiebreak will be the 7th best Pentamind score; the third tiebreak will be use the 8th best scores. Two long session pentamind scores must be applied towards a contestants’ final Pentamind score. Meta event scores such as the Amateur Poker World Championship or Eurogames World Championship will not count towards a Pentamind World Championship score.
