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.
In addition to the 15 dice representing your increasing harvest, there are 2 tokens representing '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.
