The number of Android-based gaming devices is growing fast with yet another one, the Wikipad tablet, being officially announced yesterday.

The device, consists of a tablet that slots into a proprietary game pad, is the latest of a flurry of Android devices that have included Nvidia's Project Shield, the Archos Gamepad, the Ouya, the Gamestick, the Sony Ericsson Xperia Play as well as a raft of white-labelled portable gaming consoles.

Wikipad will also launch a 10in model soon although we’re not sure whether the dual-analog stick controller will be a good match.

As for the 7in model, it is very similar to the Google Nexus 7 with some notable improvements. Like the Asus-built device, it is powered by a quad-core Nvidia Tegra 3 SoC with 1GB of RAM, 16GB onboard storage, a 7in 1,280 x 800 pixel IPS display with a “scratch-resistant military grade” layer, Android 4.1 Jelly Bean, a front-facing 2-megapixel camera, a microUSB port, a 4,100 mAh battery, dual-band Wi-Fi and Bluetooth 4.0.

In addition, the 7in Wikipad also includes access to Nvidia’s TegraZone, a microSD card slot and a microHDMI port. The tablet and the controller weigh 760g together.

The Wikipad will go on sale in spring in the US for $249, around £160 and will be available in a number of territories outside North America.
