How to play
If it’s fast you want then press the “Play” button and play it as a game. Set your difficulty level and press “Start”. This will fast-forward you through time so you can control the grid for a whole day in just 10 minutes. See how well you did by colour of your sparks: green for excellent, blue for OK and red for “Oops, I could do better!”.
Although you can’t actually play the game from here, you can watch a video of one.
