Deep river, mysterious because of the brown that covers it in the eyes of those of us who live above, hides thousands of species that coexist in that muddy and mighty ecosystem, where silver beings swim with the current looking for small prey and escaping from the larger ones. Fish, predators and birds are confused with canoes, rods and the odd lost shoe in this exciting search game that will take your breath away. Accumulate as many letters as you can by responding to the search prompts. Become the best fisherman on the Paraná River, finding the species or lost objects that the cards ask you to win a race played at the speed of the current. Place all the river cards on the table face up in the way you prefer. Place the stacked slogan cards face down. Take a card from the deck of slogans. The player on the left is asked to call out a number from 1 to 6. The mentioned number will show what and how much the player has to catch. If the number you touch is the one with a picture, "Everyone should search at the same time." The first to find it wins. If the player points to a drawing that does not correspond at all to the mission, they will lose a turn. If the player completes the mission in less than 30 seconds, he keeps the slogan card. If it fails, it puts it at the bottom of the deck. The winner will be the player who has won the most cards after four rounds.
