A recent sports betting bust in India illustrates the often unheralded ingenuity that many bookies are capable of employing to ensure that sports bettors are able to enjoy their chosen form of entertainment.

Last week, Indian media outlets reported the arrest of seven individuals accused of operating an illegal cricket betting ring out of a luxury flat in the state of Uttar Pradesh. The bookies reportedly utilized online betting exchange Betfair to set real-time in-play betting odds on Indian Premier League (IPL) matches for their wagering clients.

So far, nothing all that remarkable about this bust. Until you get to the gang’s technology, which was custom designed for the group by a local electrician with skilled hands and a gift for not asking too many questions.

The electrician rigged up a connection of 16 bog-standard Nokia mobile phones (chosen for their long battery life) that enabled the bookies to simultaneously communicate with multiple punters. For this, the electrician charged the bookies the low, low price of Rs 27k ($420), with a 32-handset model available for Rs 50k.
