An electronic puzzle comprises a puzzle body including a plurality of lightable positions, each each of which is capable of being illuminated in one of a plurality of colours. Digital circuitry establishes a colour state vector defining a pattern of colour changes for each lightable position. Control circuitry interconnects with the digital circuitry to change the colour of at least one of the lightable positions to the next colour in the colour state vector in response to a player's manipulation of the puzzle body.
