Petrichor is the scent produced when rain falls on the dry ground. Fittingly, then, in this game, players play as clouds which, eventually, rain on the ground, ready for crops to be harvested. Petrichor uses both action selection and area influence mechanisms.
In the game players have a hand of cards which set out the four different types of weather which can occur in the game – frost, sun, wind and rain. Each card is used in two ways, to determine which action a player can take on their turn, but also what weather types will happen at the end of the round. A player can either vote for the type of weather they played or the next weather clockwise round the track and place a voting marker there to indicate their choice.
Players can also influence when crops are harvested, this does not automatically happen at the end of each round. Instead of voting for a type of weather players can take a victory point from the harvest die. When all of the dice show the harvest symbol, a harvest will happen at the end of the round, during which crops can be scored. Even if players do not score a lot of points for their crops they can still score points for having the most tokens on one of the weather types which took effect in a particular round.
There are a variety of crops in the base game and they need to different number of water droplets on them to grow. However, some crops (coffee and rice) also require certain weather conditions to grow fully. This means players need to be careful of what weather conditions will happen at the end of the round if they are trying to score these crops.
