Skip Stones — free browser game

Skip Stones is a small physics game played in side view over a quiet pond. A stone rests in your hand on the left shore and you get five per round. To throw, press the canvas and drag in the direction you want to throw — the swipe vector is the throw direction, and the drag length is the power. While you drag, a faint arc previews the trajectory and a small power bar fills above the stone; dragging backwards shows a red X and cancels (stones only fly to the right). Release to launch: gravity pulls the stone down, and when it meets the water surface one of two things happens. If the incoming angle is shallow enough and the horizontal speed is high enough, the skip counter ticks up and the stone bounces with reduced energy; if the angle is too steep or the speed has bled away, the stone sinks and that throw ends. The skip counter tracks the current throw; the round score is the sum of all five throws. Two or three lily pads float on the water at random spots: clip one while you're hugging the surface and you bank a +2 bonus plus a strong extra hop — the move that rescues a dying arc or pushes a throw into double digits. The browser saves your highest round score; after the fifth throw the overlay shows your total and lets you tap (or hit R) to start a new round. Ideal technique: a firm, slightly downward swipe so the first touch lands just in front of a lily — chain the bonus and the run keeps going; floaty arcs lose energy and die fast, while steep throws sink on the first hit.
