You are blue, at the bottom. The PC is green, at the top. Tap one of your marbles, then tap a glowing hole. You can step to an empty hole next to it, or jump over any marble next to it into the empty hole just beyond. Jumps chain: after a jump, if the same marble can jump again it stays picked up and only its further jumps glow — keep jumping, or tap the marble again to stop. Get all ten of your marbles into the green triangle at the top before the PC gets all of its into your blue triangle. Fewest moves wins.
