On the Subject of Not The Screw

Don’t... screw up...?

• Use the color of the holes to determine a starting and ending position in the grid below.
• Your current row is marked by the position of the A button. If B is to the left of both C and D, you are in the left two columns. If B is between C and D, you are in the middle two columns. If B is to the right of C and D, you are in the right two columns. If C is left of D, you are in an odd column. If C is right of D, you are in an even column.
• The ending position’s column is indicated by the position of the red hole. The row is indicated by the position of green among the non-red holes.
• To traverse an edge, put the screw into the hole of the edge’s color and press the lettered button associated with that edge. Pressing a lettered button that does not match up with the selected color will incur a strike.
• You must travel through every color, every letter, and every number at least once. You must not travel through the same edge twice in a row. You must not land on the ending position without completing all the previously mentioned requirements, although doing so will still move you to that cell.
