Despite the smoky skies in Moscow, some kids are having fun dashing around on a cross between a QR classic scavenger hunt and a Russian night race. (That's drag-racing to you guys).

So while the QR codes give clues as where to find the next one, and the fastest one to get to the end destination wins, it's really just a fun promotion for as a promotion of MTS's data plan.

There's a new game every week, and redcode.mts.ru is where you solve the puzzle to claim your prize. The campaign continues until September.
