The game consists mostly of 25 double-sided fish cards which show one of 5 fish cards on each side (can be the same on both sides, can be different). These cards are spread out on the table. One player starts and places a boat token on a fish card, then flips up another fish card. If that card shows the same fish, they place another fish on the new card, etc. If the card shows a different fish, it's the next player's turn to pick a fish card. The player who places the ninth boat removes all the marked cards and gets coins from a market board. In the second round, the goal is to flip up the seventh fish; in the third round, the fifth; and in the fourth round, the third. Bonus points are awarded for correctly predicting the fish on the final remaining card. Whoever has most coins at the end of the game is the winner.
