The game shows a recommended color above the model. Bolt heads use a realistic dark Phillips cross while their metal color remains the matching cue. The recommended color receives a subtle pulse.
π¨
Match three colors
Every removed bolt enters temporary storage. The message below the slots tells you how many more of the current color are needed. Three matching bolts clear automatically.
β οΈ
Avoid a storage jam
If every holding slot fills with unmatched colors, you are jammed. Plan ahead and remove colors that can form a set of three.
Many bolts are completely hidden beneath outer panels. They appear only after the covering fasteners and component are removed. Bolts behind another bolt also remain inaccessible until the front bolt is gone.
