Most metal structures are held together with screws and bolts, this pair is inseparable, while there is only one screw, and there can be several bolts, as in the game Screw Sorting. You are asked to sort and distribute the bolts by color, screwing them onto a screw in four pieces of the same color. Each level will offer you its own set of screws and bolt colors. The tasks will gradually become more difficult. The number of flowers will increase. You can only transfer bolts to an empty space or to a part of the same color if there is space on the screw in Screw Sorting.
