Not far into the future, a stone was found in a star — then more stones were found, and it turns out that if you combine three of these stones in the right way, you create a very valuable jewel. Whats more, you can combine them in a different way to create fuel. In Troika, you are an adventurer who has dreamed of making a fortune, so youve travelled to this star along with other wanderers. Unfortunately, your spacecraft has no more fuel, so while youd like to create jewels, if you dont also create fuel, youll die as the richest person at the end of the universe! In the game, you place all the heptagonal tiles face down on the table, and on a turn you either draw a face-down tile or take a face-up tile that someone returned to the table. You have a hand limit of seven tiles, and within that limit youre trying to collect both three tiles of the same number (to serve as fuel) and three tiles in numerical order (to transform into a gem). If you have no fuel, you cant win the game; of those who do have fuel, the player with the most valuable jewel wins.
