Bit of an odd one. Emika's announced a four date UK tour, but not announced which cities she'll be playing in. Instead, you 'preorder' a ticket for your city, then the four cities who gain 150 preorders first will have gigs put on there.

This is a new one on me. There's no venues or dates listed, so what if you order a few tickets and it's somewhere terrible or on a date when something else is happening?
