Duck Life 4 is the next chapter in the popular racing and training series, picking up a year after Duck Life 3. In this world, genetically modified ducks are outlawed, leaving one unbeaten champion. To take him down, players explore six different worlds, each with its own challenges. Players start by picking an egg—yellow, brown, or white—which determines their duck’s color while the rest of its appearance is randomized. Each world offers training sessions to level up skills like running, climbing, or swimming, except for Volcano, which skips straight to the competition. Playable in-browser on sites like KBHGames, this mix of strategy and reflexes keeps things fast-paced without being overly complicated.
