Gravity Lines: Space Puzzle

200 hand-built levels across four galaxies — and every one is machine-verified solvable before it ships. One launch, no timers. A fresh Daily Challenge every day.

Draw a line. Bend gravity. Land the shot.

Gravity Lines is a physics puzzle set in deep space. You get one ball, one launch, and a handful of gravity wells. Place them, watch the trajectory curve, and thread the ball home. No timers, no twitch reflexes — just you and the shape of a curve.

ONE SHOT, ONE SOLUTION Every level is a single launch. Place your gravity wells before you fire, read the predicted arc as it updates, and adjust until the line looks right. Then let go and watch the physics play out.

200 LEVELS ACROSS FOUR GALAXIES • IGNITION — pure gravity. Learn to bend a straight line. • DRIFT — asteroid fields. Now the route has to dodge. • WARP — wormholes. The exit is never where you expect. • DEEP — slingshots, plus everything above, combined.

Fifty levels per galaxy, and not one of them is filler: every level was generated and then proven solvable by replaying the real game physics before it shipped.

THREE STARS IF YOU'RE PRECISE Beat par and you take all three stars. Solve it the messy way and you still move on — but the perfect run stays on the board, waiting.

A NEW PUZZLE EVERY DAY The Daily Challenge serves a fresh level each day and works through the whole pool before it repeats, so no two days in a row are the same. Build a streak and keep it alive.
