What Happened Last Night in Bariloche?

A lover of mathematics and statistics, you decide to take a break from your vacation to visit the Bariloche Casino and pull off the big heist with your friends — a team game to run the martingale your grandfather told you about a thousand times since you were a kid. The job was going perfectly until one of your friends fell ill and you had to step in to cover his bet. You didn’t have the money, but miraculously a helpful loan shark approached, offering to cover the stake in exchange for your flashy Rolex President — yes, the very lucky watch that has been in your family for nine decades and that you “borrowed” from your father before the trip. The ball dropped in slow motion, you closed your eyes and when you opened them again you watched it bounce whimsically until it landed on the damned 0. Frustration turned into fury — whether from the extra drinks you’d had while winning or from the panic of losing a family heirloom, you can’t say — but in a foolish move you snatched the watch from the loan shark and ran off, crashing headlong into the Casino security team. After a futile scuffle, you slowly blacked out as you saw the guards dragging you and your friends down the hotel-casino corridors. With a brutal hangover, you wake up locked in a hotel room; in just one hour the police will arrive to take the loan shark’s statement and the Casino authorities’ report.
