Wii Fit has barely broken a sweat to romp to the top of the UK All-Formats Top 40 in its first week on sale.
In the process it hurdled the previous Nintendo record set by Mario Kart just a few weeks ago to become the third fastest-selling game ever, netting around GBP 16.3 million.
Mario Kart Wii managed to hold onto second, though, although sales were down a significant 62 percent. And Mario & Sonic at the Olympics clung on at third to make it a Nintendo-dominated podium for the week.
Further down and Gran Turismo 5 Prologue took four, PES 2008 took five, and Call of Duty 4 climbed a little to six.
Then came SEGA Superstars Tennis at seven, Brain Training at eight, UEFA Euro 2008 at nine and Rainbow Six Vegas 2 at 10.
Big movers this week were WWE SmackDown vs Raw 2008 up from 34 to 21, while Condemned 2 tumbled down from 13 to 25, and Carnival Games plunged from 12 to 22.
Interestingly Halo 3 managed to bump its way back into the charts at 31, just below the other new entry this week, SingStar Summer Party.
