A two-player abstract strategy board game by Richard Moxham.
Morelli (named for a character in Julio Cortázar’s novel Hopscotch) is played on a board divided into 13 x 13 squares and coloured in concentric bands with the successive shades of the rainbow: outermost band of 48 squares in red, through orange, yellow etc, to a single central cell in violet (the Throne). Two players, Black and White, begin the game with 24 dual-coloured pieces each with their colour facing up, all disposed initially on the red band, and take turns to make inward Queen-moves with one piece at a time. The aim is to occupy the Throne with the King of one's own colour by centring a frame upon it (that is, a rotationally-symmetrical arrangement of four friendly pieces) at any distance. The occupant of the Throne at game’s end is the winner. You can watch a demo below.
Components: Cotton case, pad, 50 dual-coloured laser-cut acrylic discs (10 mm diameter, 6 mm tall approx.), 2 cylinders in 2 colours.
