On the Subject of Decolour Flash

Whether you think you can or think you can’t, you may be spending too much time thinking about it.

• A Decolour Flash module cycles through three displays with a break indicating the end of the sequence. Each word-colour pair refers to a position in the hexagonal diagram below. The colour refers to the colour of the cell, and the word refers to the single-letter abbreviation in the cell.
• Note down these three positions — your goals. Then press either button.
• The display will then cycle three positions with no break. These positions are the vertices of a triangle in the diagram.
• Press the ‘NO’ button to remove the currently-displayed vertex from the triangle and add the other vertex that would form another triangle with the remaining two vertices, thus moving your position in the diagram.
• Travel to each of the goals in order. Press ‘YES’ when a goal is displayed.
• After reaching all three displays, travel to the central cell of the diagram to disarm the module.
• Attempting to move off the grid, pressing ‘YES’ on an incorrect display, or moving to the central cell without submitting all three goals will incur a strike.
• Hold ‘NO’ for at least one second to return to the initial sequence. This will erase your progress and take you back to the starting position.
