The New Nintendo 3DS has its very own easter egg to unlock when players load up the build-in web browser.
The trick, which becomes available when players tap out the iconic Super Mario Bros. theme on the touch-screen, brings up a neat brick/block breaking game. The tapping sequence can be input when opening a new tab/browser on the device, which will prompt up a "Stage Select" screen.
