01Core mechanic
Stack matching colored nuts onto bolts until every set is perfectly sorted.
02How a run ends
The run usually fails when a move creates isolated gaps or removes the free space needed to rearrange later pieces.
03Opening plan
Spend the first turns reading the full board, identify the non-reversible move and preserve at least one flexible route.
04Common mistake
Do not solve only the most obvious local match; check what that move leaves behind for the following turn.
05Advanced tip
Keep one bolt empty as a buffer and finish nearly complete colors before breaking apart a useful matching stack.
