I have had to sit in front of my computer screen, spending an hour or so most days over the past five weeks, working through the offers. That said, it has not been completely free. I don't even have to pay tax on my winnings. The money I have made has been absolutely risk free, it's not been about gambling but about playing the system – and it was inspired by Guardian Money. I've taken up 31 offers so far – and I've made in the region of £770. Over the past month I have researched and used every decent online free bet introductory offer from a bookie.
