Why choose a such a large deposit bonus?

The obvious advantage is the free bonus funds that you receive when making your first deposit. This large initial bonus boost is ideal for those bingo players who are looking to fully test and try out a bingo site before going on to gamble with more of their own money. These free funds enable you to play a wide selection of different games, so enabling you to become comfortable with the software and little quirks. These large 400 deposit bonus offers can help reduce the risk of bingo players gambling their own money and then being left disappointed. Not only this, with such a large bonus on offer it means you can play even more games of bingo and so increase your chances of winning or picking up and additional prize.

The pitfalls and dangers of a 400% deposit bonus

It may seem odd; but there is one area where bingo players need to be careful when looking for 400% bingo bonus sites. Virtually every bingo site that offers a 400% deposit bonus will apply a wagering requirement which is often hidden away in the terms and conditions. A wagering requirement is the amount you will need to wager, gamble or play through before you’ll be in a position to be able to withdraw any winnings you make from your bonus funds. You can make a withdrawal before hitting the wagering requirement, but you will forfeit any bonus that you may have accrued. A usual wagering requirement is 4X your initial deposit plus any bonus funds that you receive. An example would be that you deposit £10 and get £40 free. If the wagering requirement is 4X you’ll need to wager £50 4X before you can withdraw the bonus funds. This equates to £200 that you’ll need to wager. Therefore, although a large bonus offered can be ideal for fully testing out a bingo site, it can also leaves bingo players disappointed when they try and withdraw their bonus winnings.
