A FRESH NEW LOOK The redesigned main menu puts everything one tap away: - Scroll Quest – multiple guided coding adventures, from first steps to tricky puzzles - Free Play – an open coding canvas for your own inventions CODING ADVENTURES WITH DASH Travel through the African Grasslands, the Arctic Wilderness and even Outer Space to uncover new ideas for your robot. Transform Dash into a ferocious lion, dodge asteroids together, play a game of Marco Polo, and much more. Every challenge introduces a new coding concept – sequences, events, loops, conditions and variables – through play. CREATE YOUR OWN INVENTIONS When you're ready, jump into Free Play and build anything you can imagine. Once your program is finished, transfer it to Dash – the next time you turn Dash on, it runs your code without being connected to an iPhone or iPad. HOW TO GET STARTED 1.

The update brings new sounds, personality and abilities and may take up to 10 minutes. 4. Start with Challenges to learn the basics, then explore Free Play.
