Fin Flinger is a free online slingshot game where you aim and launch fish across cleverly designed levels to knock out hidden target fish. The core mechanic is simple but satisfying — pull back, line up your shot, and send your finned projectile flying through small-home-style obstacle arrangements. Each level hides target fish inside or behind structures, and your job is to hit every single one to advance.

What keeps Fin Flinger fun is the puzzle-like quality of each stage. Structures are stacked in ways that reward smart angles over brute force. A single well-placed fling can trigger a chain reaction that clears multiple targets at once. The levels ramp up in difficulty gradually, introducing tighter gaps and more complex layouts that make you think before you fling. The fast-paced rounds mean you can jump in, complete a stage, and keep going without any loading downtime.

Fin Flinger is a great pick for fans of casual physics games, slingshot games, and anyone who enjoys the Angry Birds-style formula with a fishy twist. If you're searching for a free fish slingshot game, a fun browser-based casual game with no download, or a quick skill game to play between tasks, Fin Flinger checks all those boxes. Play it free right now directly in your browser on any device.
