Sink or Float is a casual browser game where players test their physics intuition by guessing whether random objects will sink or float in water. With hundreds of unique items ranging from everyday objects to bizarre surprises, the game challenges you to make quick decisions under time pressure. Each correct guess earns points, but wrong answers drain your life—can you survive until the leaderboards? Simple to learn but hard to master, it’s perfect for quick play sessions or long-term high-score chasing with friends and family.
