Tied Up is a free online arcade survival game where you control a small ball tethered to a larger ball via a spring joint, using momentum and physics to dodge incoming enemies and fight back. The core mechanic is deceptively simple — move your mouse, swing the connected balls, and use the natural pendulum motion to survive relentless enemy waves.

Each wave cranks up the difficulty, throwing new threats at you that demand sharper timing and smarter positioning. With only 3 lives per round, every collision counts. The real skill comes from learning how to weaponize your larger ball — swinging it into enemies rather than just running away. High score chasers will find plenty of replay value here, since each run feels slightly different and there's always room to squeeze out a few more waves. The physics feel satisfying and responsive, making near-misses genuinely tense.

Tied Up is a great pick for fans of casual arcade games, physics-based skill games, and one-player mouse control games. If you enjoy wave survival games online, ball physics games, or browser-based highscore arcade challenges, this one delivers quick sessions that are easy to start but hard to put down. Whether you're hunting a personal best or just killing a few minutes, Tied Up punches well above its weight as a 2025 free arcade game you can play instantly with no download.
