The combination of a promoted price cut and the release of a marquee title has helped drive Wii U sales up by 200 per cent in the US.
Nintendo of America did not offer specific numbers but said the system's sales had trebled during September (compared to August figures).
Half way through the month, the company slashed the price of its Wii U deluxe version by $50 and promoted its new flagship game The Legend of Zelda: The Wind Waker HD, which appears to be the deciding factor in the sales spike.
Similar growth has been registered in the UK. The release of The Wind Waker HD across Britain has helped drive system sales up by 685 per cent, providing respite from the console's poor performance at retail.
For the majority of the year, the Wii U's commercial performance has flat-lined in the UK and underperformed in the US.
The corporation's handheld business, however, remains as buoyant as ever. Sales monitor NPD reports that the Nintendo 3DS has become the best-selling game system in the United States for the fifth straight month.
That momentum is expected to carry on into October, with Nintendo releasing a cheaper version of the handheld called 2DS, as well as Pokemon X&Y, which in a weekend managed to sell 4 million units around the world.
