Ortho 4x4

This is the 4x4 version of the game Match 3+. It consists of 24 cards. There are four colours and four shapes. The colours are Blue, Red, Yellow, and green, and the shapes are Square, Circle, Triangle, and Diamond. Sixteen cards have coloured shapes, four cards have colours without shapes, and four cards have shapes without colour. Each of the two players gets 12 cards. In turns, the players play a card with either the same shape or the same colour as the one played last on the pile. When the players have no valid card to play, they pass. When both players pass, the one who passed first can start afresh, playing any card s/he chooses. Only a card with the same shape can be played on a card with a colourless shape. Only a card with the same colour can be played on a card with a shapeless colour. The winner is the player who first empties his/her hand.
