Narrassetch is a version of hexagonal chess invented by Arran Fernandez, currently the youngest undergraduate for more than two centuries at Cambridge University in England, in 2004 at the age of 8. The Zillions rule file was programmed by his father Dr Neil Fernandez, who also designed the pieces.

Unlike other versions of hexagonal chess, Narrassetch is playable with an ordinary chess set. The ratio between average piece strength and average pawn strength is also similar to what it is in ordinary chess. It comes in two variants, played on boards of 70 and 91 hexes respectively.
