Hmm. Good question! It depends, really. If you can get your tickets to open on your phone properly, so you can see them clearly, then our scanners should be able to pick them up just fine.
However, if you can’t open the tickets on your phone, or if your screen is cracked or damaged in some way, then you’ll need to print off your tickets to get into The Maze.
If you’re not sure – for instance, if your screen is a little bit damaged – then best to print them off, just to be sure.
