26: Tombola (2016)

Tombola is one of the more low-key operators in the egaming sector but caused something of a stir this year when, for the first time, it ventured outside of bingo to launch tombola Arcade. With an eye on social responsibility, the venture has stayed true to tombola’s low-stakes heritage, a strategy which has seen it rule the online bingo roost in the UK for a number of years. The firm has also managed to maintain a top three position in the Spanish and Italian markets.
