Many bingo operators offer a free bingo no deposit bonus to new players in order to attract them to their bingo room. This used to be 1 or 2 pound a player, but now sites like Foxy Bingo and Astro Bingo offer £10, Wink Bingo and Gone Bingo £15, and £20 is available from Cyber Bingo. But is all this free bingo really free? The answer is yes... to a point! Some bingo players think that a bingo site is going to give them free money and then if they win, payout on that free money. In an ideal world that'd be nice, but bingo sites are businesses and unfortunately they can't afford to pay out in this manner. In fact the free bingo money is really there to get you to spend money.
When choosing a bingo site it's well worth reading the terms and conditions associated with any bonuses given, including deposit bonuses. Usually if you win using free cash you'll be required to make (and play) a deposit. This may be £10, or in some cases as much as 4 times your winnings. It's very rare to be able to cash out without ever spending money at a bingo site!
So yes free bingo money is free, but it comes with terms and conditions attached. More and more bingo sites are becoming wary of loopholes and therefore closing them up. For example Loquax Bingo used to get multiple same user sign ups for free bingo, however this has now stopped.
It would be a shame if bingo sites stopped the free bingo bonus altogether or switched to a deposit bonus deal like Gala and Mecca Bingo offer. However, for that never to happen players need to become atuned towards the bingo site and see it as a place of fun and enjoyment, not a resource to get free cash in their pockets.
