Whilst the sheer number of online casinos trying to woo you to play their online slot games can be somewhat overwhelming, this fierce competition comes with the pleasant benefit that the promotional bonuses offered to keep and retain players have become pretty keen.

Of course it’s vitally important to choose where to play based first and foremost on the reputation of an online gaming site for secure and fair play but, if that box is ticked, hunting out the best online casino bonus packages can be a canny way to get the best value for money out of your online slots sessions.

Casino bonuses come in several flavours, but the most common incentive you’ll see advertised is the “Welcome Bonus” aimed at bringing new players through an operator’s virtual doors. These typically break down into two types – the ‘no deposit’ bonus and the ‘match’ bonus. The first is a very attractive bonus to any new player seeking to explore a site’s online slots, since it’s a gift of a bundle of free cash to splash on your entertainment without requiring any deposit into your new player account after signing up.

The ‘match’ bonus is a complementary incentive of free bonus money that is calculated as a percentage of a player’s first deposit of real money into their account. The common figure for this is 100% so it effectively doubles your spending power, matching your first deposit pound for pound up to a specified limit.

After you’ve pocketed a site’s Welcome Bonus, you’ll often find that’s not the end of the bonus story at the best online casinos since retaining your custom is becoming increasingly important too, so be aware of the loyalty bonuses on offer when researching where to play. These are less uniform than the Welcome Bonus packages, but common rewards are ‘comp’ or loyalty points that accrue as you make use of your account and can be redeemed for cash or prizes, or reload bonuses that are offered as ‘match’ bonuses on a deposit other than your first as a new player.

One final bonus to look for if your primary concern is playing the best online slots is a freespins bonus. This is becoming an increasingly popular offer, and is a gift of a fixed number of freespins to play on specific slots – a nice way to try out some great games with the added excitement of winning extra bonus money from those free-spinning sessions.

Now, betting sites and online casinos are clearly not operated as charities so all extra bonus money paid to you will come with some rules attached – for obvious reasons it would be madness if you could simply cash it out straight away – and this is called the ‘wagering requirement’. Put simply, this is a requirement that all bonus money (and only bonus money) has to be played through a specified number of times before the player can freely cash it out.

There may also be limitations on which games can contribute to a wagering requirement and how much of each wager is counted. This can all seem a bit complicated, however if you regard bonus money as simply extra funds to spend on playing your favourite slots you’ll find it’s a great way to wring the best value-for-money out of your online sessions.
