Drag back from the launch point like a slingshot, then release to fire. Farther drag = more power. Hit the neon ring to score — 3 misses and it's over.
Trajectory is a free online artillery aim game built around real parabolic physics: pull back to set angle and power, then release to launch a glowing shot at a distant ring. Distance, target size, wind and vertical drift all ramp up with your score, making sustained accuracy one of the hardest aiming challenges you'll find in a browser.
