Early signs point to THQ's art tablet accessory for Wii, uDraw, as being a sales success.
The publisher is not releasing figures as yet, but has enjoyed a dramatic leap in its share price since the $70 peripheral's release on November 14.
At the start of the month THQ's shares had dipped to a recent low of $3.90, but yesterday were up 31.8 per cent to $5.14 - the company's highest value since June.
THQ is known to have produced 1.3 million uDraw units, scaled up from 1 million after a positive retailer response.
Reuters reports that the accessory reached seventh in Amazon.com's videogame charts, in a period of strong competition from the likes of Black Ops and Kinect.
"U-draw is selling so well I'm afraid they'll rename the company THQ-Draw," joked THQ VP Danny Bilson on Twitter last night.
