Find your next little obsession.

Touch a knot of the vine and drag sideways to swing everything attached to it. Berries you sweep through join the vine and keep swinging, so one good swing can set off a cascade. Branches that touch the hedge get pruned. A preview shows exactly what each swing will do before you let go. Clear ten garden beds, from 8 berries to 63, in as few moves as you can.

10 garden beds · Par-based stars · Saved progress

1. Touch a vine knot with one finger or the mouse and drag sideways. Right swings clockwise, left counterclockwise, from 30° to 90°.
2. While you drag, the preview shows every knot's path, the berries you will catch and any branch the hedge will prune. Let go to swing.
3. Caught berries become new knots and keep swinging in the same move.
4. You cannot swing around the same knot twice in a row; that knot is shown dashed.
5. A branch that touches the hedge is cut off with everything beyond it. Clear the bed within par for three stars; each cleared bed opens the next.

Fly a firefly through a night meadow, five seconds at a time. When each round ends, your path becomes an echo firefly that flies it again every round, gathering nectar for you at double points. Touch any echo and the run is over. Fly through closed buds to set up what your future echoes will gather; an echo that gathers nothing soon fades away.

Endless runs · 5-second rounds · Best score saved

1. Drag anywhere with one finger or the mouse; the firefly moves with your drag. Arrow keys also work.
2. Each round lasts five seconds. Your path then becomes an echo that repeats it every round.
3. Echoes gather nectar for you at double points, but touching one ends the run. They are harmless for the first half-second of each round.
4. Closed buds show the next round's nectar. Fly through them to set up your echoes. An echo that gathers nothing for two rounds fades away.
5. Each nectar is worth 1 point plus 1 for every echo still flying.
