Miitomo might not be available globally yet but if you've used our handy guide then you'll know it's pretty easy to get it on your device no matter where you happen to be in the world.

Since the game launched there's been a lot of interest - which is perfectly understandable, given that it's Nintendo first serious attempt at a smartphone release - and dedicated players have spent the past few days digging deep to find any secrets it might contain.

The guys over at GameXplain have discovered a handful of cool Easter Eggs which are easy to miss. These are all focused on the comments section, where you can leave replies to questions or other people's answers.

Some are pretty simple - typing "Dog" or "Cat" makes your Mii's face change momentarily - but the most interesting has to be "Direct", which makes your character do the iconic Nintendo Direct stance made so popular by the late Satoru Iwata. "Game Boy" also generates the famous "Mario Coin" sound.
