Rainbow River is a grid-movement tableau-building game where players compete to get the most resources from an ever-changing board, with a unique setup for each game. Players play as explorers trying to piece together a cohesive map of the mystical rainbow river and fighting over map scraps. You start with a randomized board and a unique Preference card. As the game develops, the board will shrink, and players will attempt to collect map tiles that will advance their river. Build the longest river in order to secure victory! —description from the designer
