In-game betting has changed how many watch sports, and even some gamblers warn of consequences

Wayne Madd woke up with a name on his mind. Call it a hunch or feeling, it was a wager he felt he had to make. Like thousands of other Canadians, the twenty-something Toronto sports fan has the betting bug and finds himself making a series of bets almost every night.

One of his favourite bets: guessing which player will score first. On this night in early May, as the Toronto Maple Leafs faced off against the Florida Panthers in an NHL playoff game, his money was on Leafs forward Noel Acciari.

"I bet $25 dollars and it's a $650 payout. It's going to happen. I just have a good feeling" Madd says. "I woke up this morning and I was like, Noel Acciari is going to score the first goal. Every game I bet the first goal. When I wake up in the morning, a name pops into my head and I make that bet." 

As it turns out, Madd's premonition didn't pan out. Accari didn't score in what was a 4-2 loss by the Leafs in Game 1 of the team's second-round series against the Stanley Cup-bound Panthers.

But on this rain-soaked May evening, Madd is among thousands of Maple Leaf fans who have gathered just outside the arena to watch their beloved team on a giant screen, many of them furiously glancing at their phones and then back up at the game, following the prospects of their wagers as much as they are the actions of their team.
