The Ryder raft you float down the river on a raft made of logs. Your goal is to guide the raft as far down as possible to the river, avoiding a lot of obstacles. You will come across the dangerous rocks, trees, beavers (who cut trees, make more obstacles!), And even elk, all of which can sink the raft. For each segment of the river you are not traveling earned 125 points, and additional bonus points can be earned by collecting gold nuggets that you will encounter on the river from time to time. You start the game with three rafts (rafts can earn a bonus), and the game ends when all the rafts were sunk. Multiple difficulty levels, which control the rate of flow and the speed of the beaver and elk.
