Slingshot Orbits

Slingshot Orbits is drawn in ink on a sheet of lined paper. The red dot circles the current orbit. Shoot, and it flies along the tangent. Between some orbits sit grey asteroids — touching one counts as a miss, so the right moment is the one where the line reaches the next orbit and slips past the rock. On the first two orbits of every sheet a dotted line shows where the shot goes. Then the line disappears and you shoot by eye. Ten orbits complete a sheet. Every sheet is generated fresh and is always solvable, with more rocks, faster spin and wider gaps as you go. Black ink, a red pencil dot, a notebook margin. Plays offline without ads or purchases.
