Thames & Kosmos, the North American branch of this company, is taking a different approach to the Lost Cities line of games. It already launched in the U.S. in 2015 with those first two titles (along with four others), and for now it's holding off on releasing an English-language version of Lost Cities: To Go. Instead Thames & Kosmos will be first to market with a new 2-4 player game in the line: Lost Cities: Rivals, which will be available for demo games at Gen Con 2018 in early August before a retail release later that month. While the basic card play remains the same as in other LC games, what's new in this title is that you must win auctions in order to place cards in your expeditions. In more detail:
On a turn, you can either reveal the top card from the current pile (adding it to the display) or auction the cards on display. In the auction, you must raise or pass, and once only a single person remains in the auction, they pay the amount bid to the center of the table, then take any cards that they want to play and start or add to expeditions. Placing the same number in an expedition is okay. The auction winner can also place one card from the display in the box out of play. The auction winner ends their turn by adding a card to the display.
When the final card of a pile is revealed, divide all the coins in the center of the table equally among all players, then bring in a new pile to continue play. Once the final card of the final pile is revealed, the game ends immediately with no distribution of coins. For each expedition, a player scores the number of footprints on the numbered cards. If they have a wager in that color, they double that value; if two wagers, they triple it; etc. A player also scores 1 point for each gold coin they hold and 8 points for each expedition that contains at least four number cards. Whoever has the highest total wins!
