Swim Good is a free online fish survival game where you control a hungry fish circling through the water, chomping up worms while deadly spiky urchins try to end your run. The core loop is simple but brutally addictive: eat to score, keep moving to survive, and never let those urchins catch you off guard. One bad turn and it's game over.

What makes Swim Good genuinely fun is how quickly the tension builds. The worms keep spawning in unpredictable spots, which means you can't just stick to a safe path — you have to commit to risky routes if you want a high score. The spiky urchins fire at you, so staying still is not an option. Timing your circles, planning your chomps, and reacting fast are what separate decent runs from great ones. There's no progression system or unlocks to worry about — just pure reaction-based gameplay that gets harder the longer you last.

This game is perfect for players who enjoy quick arcade-style challenges, fish games online, and survival games with simple controls. If you like avoid-the-obstacle games, one-player browser games, or just want something fast and free to play during a break, Swim Good delivers. It works great as a free online fish eating game with no download required, making it easy to jump in and play directly in your browser anytime.
