Nintendo's Mario Party 9 is out this week in Europe with a North American release to follow, but if you're not sure what's new in this 11th instalment in the series — don't forget Mario Party DS and Mario Party Advance — Nintendo's put together a video to explain.

The trailer highlights some of the brand new boss fights with Mario series staples including Wiggler and Blooper that await once players reach the end of the board.

We'll have our Mario Party 9 review very soon.
