Orchard is a quick solitaire 'tile laying' game that plays in under 10 minutes. The aim of the game is to harvest fruit (score points) by playing cards so that their fruit trees overlap other trees already in the orchard that bear the same fruit. The more trees you can overlap, the more fruit you'll pick.
As well as the 9 double sided cards, you'll need 15 dice (of 3 colours) to keep track of your increasing harvest, and 2 cubes to represent 'rotten' fruit. These allow you to lay a card that you wouldn't otherwise be able to - but come with a points forfeit. So you must decide if and when to play them.
