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.

See Appendix FLASH for Colour Flash variant identification.

• 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.
