Congratulations go to:

I will post the answer to the problem later this week, but there is a discussion on-going at our Mathematics Competitions Community on Google Plus. Unlike the standard Tower of Hanoi, colouring the discs creates some limitations in the possible moves. It also destroys the simple formulas that are associated with the standard puzzle.

This could form the basis for an interesting project. Start with a 2-colour Tower of Hanoi, with alternating colours, and see whether you can find a pattern such that you can calculate the number of moves needed to solve a 100-disc tower!

More on this coming soon...
