Revealing a piece here means this puzzle on this date stops counting for the leaderboard. Every other puzzle and date is unaffected.
Drag the slider to lay pieces down one at a time. Each board can have many valid solutions — tap New solution to shuffle to another.
Tap a tile to select it (its inline highlight lights up). Tap it again on the right half to turn clockwise, or on the left half to turn anti-clockwise. A translucent ↔ flip button floats above the selected tile only when that tile is asymmetric/flippable. Drag anywhere to slide the selected tile; the highlight glows green where it fits. Release over a fitting spot to lock it in. Stuck? Check my tiles says whether your placement can still reach a solution — each check costs you time, so use it sparingly. Leave today's cells uncovered to win.
