Ruby Bingo members have until the end of February to get involved in a special promotion that provides the chance to live free of energy bills for a year.
Energy Buster runs right through until February 28th, with each member of the site receiving one entry into the prize draw for every £10 wagered on Ruby Bingo's online bingo tickets. However, there are also other ways to earn a place in the prize draw, some of which take place in specific areas of the site - such as the Cloud Nine bingo room.
"You will be able to earn extra entries by bingoing on the Energy Buster pattern in Cloud Nine!" the online bingo site explains.
There are other advantages to wagering on Ruby Bingo over the course of February, with payouts for the people who participate the most. By combining the number of tickets bought with their face value, the online bingo site is able to determine who is its most loyal customer - and promises to pay £75, with runner-up sums of £50 and £25 for second and third.
Anyone finishing elsewhere in the top ten is promised £10 in bingo bonuses to put towards their tickets in future months.
