One more pull, Bob tells himself, and i'll win back the money i lost. Bob has been playing at the video slot machine for a few hours. He won $100 in his first few attempts.and although he did win a couple of times again, it was only $1 to $5 at a time. Bob tried placing the maximum bet thinking that it might work but even after playing over four hundred times, he hasn't made more than a couple of dollars. In fact he has already last $300 Why does Bob continue to play the video game even after losing $300.
