Puzzle pieces mechanics are key for me. Drag and drop each piece into its correct position on the transparent image. i find that grouping similar colors is a good strategy to finish faster.
Dragging and dropping pieces to fit the image is the main action, choose difficulty easy medium or hard then scatter pieces appear across screen for you to arrange.
No extra buttons or toggles are stated.
Quick strategy is to identify edge pieces first, then group similar colors. This builds a strong foundation to arrange the scattered pieces faster.
