Xenon Profiteer Boardgame

Xenon Profiteer takes one of the more useful strategies found in the paragon of deckbuilding games, Dominion, and builds an entirely new game around it, while also incorporating a delightfully nerdy (well, if you’re into the noble gases, at least) theme. The rules are simple to learn, although they could be written more clearly, and the game concludes in a reasonable enough amount of time that you could play it twice in an evening.
The Dominion strategy in question has a few names, but I think most players know it as the Chapel strategy, named for the first card that allowed players to execute the plan: Keep trashing the least valuable cards in your deck. While deckbuilding implies that you’re trying to build a big deck, keeping a deck small, with only the most valuable cards (worth the most money or allowing strong actions), is a very competitive strategy in Dominion and often difficult to beat when it’s executed correctly.
Players in Xenon Profiteer are trying to trash cards by design, and in fact get at least one chance every turn to trash one or more cards in their hands. The goal of the game is to isolate xenon cards in your hand so that you can use them to complete contracts, cards that return points and/or money in exchange for one to five of those xenon cards. There are four cards showing different types of gases, and on every turn a player may add “air,” a set of one of each of those cards—hydrogen, oxygen, krypton and xenon. (There’s a cute note at the end of the rules on where there are no argon cards.) A turn begins with “distillation,” where a player may remove all gas cards of one element from his/her hand, with hydrogen first, krypton last. If you have no gas cards other than xenon in your hand, you have isolated the xenon and may place those cards on the table or use them immediately to fulfill your open contract. After distillation, a player may add air and also gain $2, and then may choose to either buy a card from the market or to place a bid token on any of those cards, which may be worth $1 to that player later in the game.
