The board consists of a 5×5 grid: a border of 16 squares with printed action symbols and then 9 blank squares in the centre onto which cards are dealt. Meeples are placed one at a time on the spaces at the edges of the board (not including corner squares). You cannot place a meeple on a square the opponent has a meeple on already, nor on a square facing opponent’s meeple. Once all meeples are placed, players then execute the actions on the border squares the meeples are on and also take the cards from the centre that match the row and column of the border meeples.
The game is predominantly scored and won by playing tribal cards to your display. These give advantages during the game and victory points at the end. Usually cards are played (or discarded) immediately once drawn. A single card can be kept in hand but then requires a special action to play it (or to discard it to free the hand spot for another card). Each card has a cost in goods to play. Goods are obtained either from border spaces or from goods cards.
The display (for scoring) consists of 3 rows of 4 cards that are filled from left to right and cannot be moved once placed (barring some special cards). There is also a balance to be found between the victory point score on the cards themselves (1-3 VP per tribal card) and in the combinations per row (a full row of 4 identical card types gets you an additional 4 VP, and a full row of 4 distinct card types gets you 2 VP).
The winner at the end of the game is the player with the most victory points.
