Sort Works Nuts & Order: top-nut rules and move planning
Sort Works Nuts & Order sorts coloured nuts between bolts. Select a bolt to lift its top nut, then choose a destination with a matching top colour or no nuts. Sort all nuts by colour to complete the level.
Check a move before making it
Only the top nut can move. Compare its colour with the tops of the other bolts and look for an empty bolt. A buried nut must be uncovered before you can select it.
For planning, ask what the move will reveal and where that newly exposed nut could go. An empty bolt can provide temporary space, but filling it is not automatically progress. Look for a continuation before using it.
When the position becomes crowded
Check every top colour again. Do not assume that a legal transfer will improve the position. If you decide to retry using an option available in the game, change the decision that used up your working space instead of repeating the same sequence.
About levels 102, 127 and 282
The suggestions above are not verified solutions to these numbered levels. A level answer needs the exact starting arrangement from this game. Compare the number of bolts and every colour in each stack before following a video or a list of moves. A matching number alone does not identify the same puzzle.
Not a screw-removal puzzle
This game sorts nuts by colour. It does not ask you to remove screws so wooden planks fall. For that different task, see the screw-puzzle collection.
