Driftwood is a daily coastal jigsaw puzzle. Each day a new procedurally-generated scene — misty harbours, rolling dunes, marble tide pools, fog-wrapped sea stacks, breakwaters, and coves — is sliced into 48 pieces (6 columns × 8 rows). Drag pieces from the tray on the left onto the ghost-grid board on the right. Drop a piece on any empty cell and it stays parked there (shown with a dashed outline) — pick it up again, rotate it in place with a double-tap, or slide it around while you work out the scene. A piece locks in with a chime when placed in its correct cell at 0° rotation.
Right-click or press R while holding a piece — or double-tap a piece in the tray on touch devices — to rotate it 90° clockwise. Each piece requires 0° (no rotation) to lock; if you drop a piece on its correct cell at the wrong angle, the cell flashes amber with a rotate reminder. Daily mode produces the same scene for all players sharing the same UTC date; Infinite mode generates a fresh random scene every play.
