The Game & Watch: Super Mario Bros. handheld officially released on November 13, and it gives you yet another way to enjoy the legendary platformer. However, there are also a number of little Easter eggs and secrets that you can use, and Nintendo gave us some tips on how to access them.

Once you beat Super Mario Bros. for the first time on the device, you'll gain access to a new hard mode. This mode was lost when turning off the original NES, but thanks to the advances in technology, now you never have to lose access to it! That is, of course, unless you lose the Game & Watch altogether. It's not very big.

If you hold down the A button when on the title screen, you'll unlock "Infinite Mario" mode, which removes the life limit and lets you keep playing indefinitely. This is a great option if you're getting the system for a younger player, or if you've gotten a little rusty over the years.
