Each round in Harvest, you first draft turn order (and the benefits that come with it), then send your two workers into town and into the fields. Plant seeds, tend fields, and harvest crops to make room to plant some more! Utilize buildings and magical elixir to amass a bigger and better harvest than your neighbors at the end of five rounds of play.
Scoville: Labs has few components, but is an expansion that adds significant depth to Scoville. Every player receives a 3x3 lab on which they can additionally "plant" peppers. You collect cross-bred peppers based on what is next to a new pepper when you place it into your lab. Nobody else can play on your personal lab board, and no one can walk through it to produce peppers either. With more planting to do, each player starts with a second "plant 1 extra pepper" token. Scoville: Labs also comes with additional wooden peppers, new recipe cards, and pepper multiplier tokens.
