A relaxing and addictive puzzle: colored nuts scattered across bolts, and your job is to group them until each bolt has a single color. The rule is simple—you can only move a nut onto an empty bolt or one whose top nut shares the same color—but as you level up, more pieces and colors appear at once, and you have to think several moves ahead to avoid getting stuck. Hard mode levels hide the color of some nuts until you move the piece above them, so you have to take calculated risks. If you get stuck, there are aids like undoing, restarting the level, or adding an extra bolt to gain space. Behind each solved set, there's also a garden that you gradually restore. How to play: tap the nut you want to move and then the destination bolt; it can only be placed on an empty space or on a nut of the same color.
