Feature slots are fast becoming the most popular variation of the humble slot machine, both offline and online. The reason for this is simply that they are usually a lot more fun and add some variety to the age old formula of spinning reels and matching symbols.

The types of feature offered vary greatly, from free spins to multipliers and even mini games where you have to complete a task with a guaranteed cash reward. Online feature slots are getting more and more advanced, for instance, the recent release of the Tomb Raider™ video slot offers, free spins, multipliers, gamle options plus two different feature mini games.

The release of the Tomb Raider™ slot machine is also a landmark for the online casino industry as it's the first game to use an officially licensed trademark. Not surprisingly, Spin Palace were one of the first online casinos to offer this new slot machine and they're also offering all new slots players a special welcome bonus of $150 to mark the occasion. This special offer only runs until January 1st 2005 so be sure to make the most of it whilst you can!
