The backs of the cards uses half brick coloured shape as a type of domino using the colour, there being 6 different colours. The top half of the card back shows 3 half bricks in the same colour, with the bottom half of the card usually showing the 3 half bricks in a different colour. There are 6 card backs showing all six half bricks in the same colour. I have come across 21 different combinations of the coloured groups which along with the 140 different cards I have amassed 778 different cards.

Note that the cards were originally handed out 1 pack per every £10 spent in Sainsbury's supermarket, these were distributed in the packet not showing a price. Due to the promotion of these cards being about six weeks the supermarket also had available packets for sale these being distributed in packets marked 50p thus enabling a customer to acquire extra packets.
