A little rearranging works wonders.
Tap a piece, then an adjacent piece to swap them. You can also swipe a piece toward its neighbour. Match at least three identical icons to collect them. Pieces fall into the gaps, and fresh finds arrive from above.
By default, matches are horizontal or vertical straight lines. Unsuccessful swaps slide back without costing a move.
Look for something special.
- Longer matches create special pieces.
There is no closing time.
Chain reactions multiply your points. Complete the current exhibit for a bonus and a fresh collection goal. There are no lives, deadlines, or last levels.
Hint highlights a scoring swap. Refresh deals fresh icons while keeping your score and special pieces. If no scoring swaps remain, the game refreshes itself. Undo rewinds up to eight turns or refreshes, including their scores and goals.
Keyboard: use arrow keys to move focus. Enter or Space selects a piece; select a neighbour to swap. Shift + an arrow swaps directly. Escape clears your selection. The game saves after every completed turn.
