Pokemon X and Y has been a huge success for Nintendo and their 3DS as the game has sold around 12 million copies combined since its October release.

For the month of February the game sold 130,000 units in the U.S. alone, reported NZ Gamer. On its launch weekend, the game moved over four million units.

Since X and Y, handheld sales have gone up as well too because of all the bundles available. A 2DS bundle was available at Target and Toys R' Us, which each store selling one version of the game as a bundle. There was also a 3DS XL model in the UK.

What is most impressive about the sales of the game, is the amount of 3DS handhelds there are in comparison to the game. Upon the four million sold on launch weekend, there were only 35 million 3DS' sold at the time.
