Sign Up Bonuses
Sign up bonuses enjoy the distinction of being the largest, most popular and most common of all casino bonuses. This is probably why all online casinos offer it. Most people choose an online casino based on the amount of money offered in the bonus. This is wrong as the amount mentioned can come with lots of clauses like only available after multiple deposits etc. These clauses are not mentioned except in fine print and can thus be a huge pain. However if you plan to stay with the same casino over time this bonus might not be such a bad idea. Another type of sign up bonus is the 'refer-a-friend bonus' which you can be entitled to if you were referred there by a friend.
Sign up bonuses differ from each other based on the amount offered, the percentage offered, the wager you must place to avail of them, the finer details attached to them etc. Sign up bonuses that do not require deposits are very rare and very small. Still they are good marketing techniques. A sign up bonus aims at getting you to spend more at the casino and get you more interested in it. Matching bonuses have the best odds of cashing out.
Once you download the online casino software, register as a real player and make a deposit you will recieve your bonus. Once you read the terms and conditions and the matching percentage you can make your choice.
