Title #1 in the series is Soda Smugglers, a game for 3-8 players that BGG is currently listing as a reimplementation of the 2019 game Heisse Ware: Krimi-Kartenspiel from Gmeiner-Verlag, although it's not clear right now whether the games differ. In any case, here's an overview:
Each round in Soda Smugglers, one player takes a turn in the role of a border guard while the other players act as travelers. In a quest to acquire coveted carbonation and its accompanying bottle caps, the border guard tries to confiscate as many sodas as possible while only the cleverest travelers will sneak across with their fizzy contraband. After each player has been the border guard (twice in a 3-4 player game, once in a 5-8 player game), the game ends and whoever has the most bottle caps wins!
Pumafiosi is a refreshingly unique blend of simple trick-taking and precarious press-your-luck. Each trick, the person who plays the second-highest card wins the round, and they decide where to place that winning card in the hierarchy. You can even choose to place your measly card at the top of the hierarchy to stake your claim on the big boss points. The catch is that these cards can be knocked down one or more steps on the hierarchy by higher-valued cards, and whoever owns a falling card is penalized!
Pumafiosi differs from the older title Rooster Booster thanks to designer Reiner Knizia:
—Increasing the strategy by narrowing the deck to a range of 1-55
—Crafting a satisfying two-player experience
—Raising the stakes by tweaking the hierarchy values and penalties
—Tailoring a theme that gives context to the rules
—Enhancing the drama by including physical penalty points
—Layering decisions with further depth and tension via one-time-use items
In each round of Hot Lead, criminal cards are displayed in a column equal to the number of players. Players then make their bid by simultaneously revealing an investigator card from their hand. The highest investigator bid takes the criminal card closest to the deck, the second highest takes the second closest, and so on. These cards are worth points equal to their face value (0-5).
Gather enough evidence on one criminal organization to convict them when the game concludes after ten rounds; in game terms, by having exactly three of a suit, you earn 10 bonus points. Ten bonus points are also awarded to those who acquire criminal cards of all five suits. If you investigate too aggressively and grab the fourth card of a suit, those criminals will sense a rat and you'll scare them underground, thereby losing all of those cards. The player with the most points at the end of the game wins.
In the game Social Grooming, players are primates who start out with a personal deck of face-down cards. Without looking at the card(s) in their hand, players simultaneously trade or keep their hand, one or two cards at a time, to form a personal collection. Once all cards have been traded or kept, players tally their collections and the highest score wins — but pairs can cancel out and special cards are not always helpful, so trade carefully!
Similar to the popular game Hanabi, in Social Grooming players hold their cards facing away from themselves...but instead of being a co-operative memory game, this is a competitive negotiation and bluffing game. Things get even more interesting once players realize that every card can either be very good or very bad for one's collection, depending on the context. You'll have to convince your opponents to keep bad cards for themselves and give great cards to you if you want to swing away with the win...
• And looping back to German publisher Gmeiner-Verlag, in March 2021 it released the Knizia party game Komplize gesucht!, which is for 3-8 players and probably not playable by those who don't understand German:
The world is full of criminal challenges, and there are plenty of prominent candidates for your next coup: politicians, artists, athletes, actors, scholars, musicians. In Komplize gesucht!, you get to name who your accomplices would be for these crimes and more.
