Competition between online casinos has led to an increase in bonus offers and other incentives. Typically, the higher the casino bonus the rare it is. One of the rare online casino incentives is the 400% bonus which multiplies your initial deposit by four. If you intend to try your luck on an online casino, you should consider starting with a 400% bonus when you sign up.

What to keep in mind when claiming a large casino bonus
Most huge bonuses have wagering requirements that have to be fulfilled before you can cash out your winnings. Keep in mind that these conditions vary from one casino to the other. First, check if the bonus has an expiration date. Bonuses can be cancelled if not used within a specified period. Other things to consider include games you can play with the bonus and minimum required deposit.
