I got my first look at Petrichor back at GenCon 2017, where the APE booth had a prototype of the game and both the stunning artwork and the clever theme (players are clouds? Sign me up!) caught my eye, although there wasn’t much available yet about the actual mechanics. The game finally hit U.S. shelves this summer, and it didn’t disappoint, with a smart combination of individual strategy and direct interaction between players, plus the replay value of a modular board that can alter the tenor of each play depending on what tiles are available and how they’re aligned.
Players in Petrichor aren’t actually clouds, but they get to place clouds on the board, adding their own rain drops to clouds to try to gain the most points from watering the various crops shown on the board’s tiles. On a typical turn, a player will play a card from his/her hand showing one of the four main actions – create a new cloud with one of the player’s own raindrops in it and place it on the tile, add two raindrops to a cloud the player is already in, take one or two of the player’s raindrops from clouds and make them ‘rain’ on the tiles below, or use the wind to blow a cloud to an adjacent tile – and then cast a vote for the weather for the next round. There are four types of weather actions, and the player can vote for the kind shown on the card s/he played, or can vote for the next weather type after that (clockwise) on the board. The player can also skip the vote and choose to reduce the value of one of the three harvest dice to bring the game closer to the next harvest; that action brings the player one or two points immediately, and the Harvest itself is when all crops are scored and raindrops on the board are cleared.
Players continue taking these actions, potentially taking a second action by playing two cards of the same type, until someone passes, after which the remaining players may take one final action before the round ends. At the end of a round – there are six rounds in the full game, or four in a shorter game – the votes on all weather spaces are tallied, and the two with the most vote tokens on them are used; the player with the most votes on each space moves up one on the weather voting track, which can be worth quite a few points at the end of the game, enough that you ignore it at your peril. Those actions can upgrade light clouds (1-3 raindrops) to thunderclouds; cause thunderclouds (4-7 raindrops) to rain; allow each player to double his/her drops in one cloud; or allow each player to move one raindrop of any color to an adjacent tile. (A cloud with 8 or more raindrops ‘overflows’ immediately, raining those drops directly to the tile underneath.)
Most tiles begin to grow once the minimum number of raindrops shown on the tile, one to seven depending on the crop, is reached – counting only drops on the tile itself, not those still in a cloud – and the tile is then eligible to score at the next Harvest. Some crops just reward points based on each player’s raindrop count on the tile. Wheat tiles give three points to anyone with drops on the tile, no matter how many, except for the person with the most drops on it, who gets two points plus a special wheat token; at the end of the game, the player with the most wheat tokens gets 12 points. Potato tiles give 7 points to the player with the second-most drops on them, but only 3 to the player with the most. Coffee and rice plants must first be sprouted, and then award more points when they develop into full-grown plants. Thus a huge part of Petrichor strategy is figuring out where best to place or move your raindrops to maximize your point total and potentially reduce those of your opponents.
The wind action is a big part of that strategy as well. If you use a wind action yourself, you can move a cloud on to a tile with another cloud on it, which causes them to merge – a way you can snipe points from an opponent who might have thought s/he had that tile’s bonus locked up already. If one of the two weather spaces activated by vote at the end of a round includes the wind, you can also use this to change the scoring of tiles, often significantly, as a sort of sneak attack. That makes the two ways the wind appears in the game particularly useful for a player who’s fallen a bit behind – more so if the player can stack up enough votes on the wind space to gain the voting bonus for the round as well.
At the end of the final round, there is always a Harvest regardless of what the dice show, and all four weather actions are activated, although only the top two are scored in the voting. Players then add the value they’ve reached on the voting track to the points they’ve acquired throughout the game, as well as the bonus for wheat tokens if the wheat tiles were used in the game, to determine the winner. Games take 45-60 minutes, and while the strategy can be quite involved because you’re searching for moves that will benefit you without helping your opponents, and possibly taking points away from them, the mechanics themselves are quite simple to learn, enough that younger players should be able to play along with the adults.
There’s also a solo mode available called the Southern Winds variant, where the board comprises six tiles (with certain tiles unavailable in this mode). You play against a neutral player, whose moves are controlled by a special nine-card deck that allows that player to make moves unavailable to you and tends toward the aggressive, which requires you as the solo player to play quite differently. The solo game goes four rounds, and the neutral player still gets to vote on weather and to reduce Harvest dice values for points, with a Harvest guaranteed at game-end. The neutral player is strong, but it’s also ‘dumb’ enough that it can’t adjust for the presence of weird tiles like the potato (second-most raindrops gets more points) or wheat, so you might want to remove those tiles from the possible layout. Solo play becomes a bit more of a puzzle, or even a bit like programming – you can work through the likely set of moves for the neutral player, and then counterprogram with a set of potential moves for yourself to set yourself up to capture the majority of the scored tiles in each Harvest. I’ve found it’s easier to focus on the tiles than the voting in the Southern Winds, and have beaten the solo player outright before giving myself the bonus for wheat tokens.
Petrichor also comes with many variants in the rulebook to further enhance play, most notably a card-drafting option to replace the random card draws of the base game, which assumes players have some experience and will further lengthen game times. It’s solid with two players, better with three or four to get more clouds on the tiles and more chance of players interacting with each other (even though you make the board slightly larger). And the artwork is truly stunning, some of the most appealing I’ve seen this year, boosted by the choice of white backgrounds for all components to brighten the table and the clear glass beads that represent the players’ raindrops. It’s well worth seeking out if you’re looking for a midweight game that’s quick to learn but can provide you with the strategic depth of a slightly heavier title.
