Best Sites to Compare Casino Bonuses and Wagering Rules

Online casinos always compete for clients’ attention, and incorporate lucrative bonuses with potentially large chances to win a big prize as one of the primary approaches for attracting more leads. Flashy welcome packs, cashback, freebies, reloads, and other mouthwatering propositions sound tempting, but the real value of a good offering lies in its terms and conditions.

For players who want to get the maximum from an activated perk and avoid unfair rules, it’s worth analysing a casino proposition at trusted reviewing websites. While not all of them are fair because some platforms promote bonuses from affiliate casinos lacking transparency, we have 4 top websites that provide honest data about bonuses and analyze attached wagering rules. Let’s discover how they can help gamblers searching for a possible way to improve their gaming results.

The Most Widely Offered Casino Bonuses

Before signing up for a particular operator, we also recommend reading what each bonus means and how it can benefit your gameplay. There are several types of promotional offerings which you can find at the majority of casinos:

• Welcome pack – the first option players meet when registering an account. It usually looks like a 100% add to the deposit and can also be enhanced by freebies or special points (to exchange in their shop).
• Free spins – allow clients to spin reels in slots without spending a cent from their casino account.
• Cashback – usually goes as a percentage (5-15% or more) of the stakes spent during a particular period. Money is returned to the players’ balance.
• Reload – can be activated after wagering back a welcome pack. Also may be represented as a % of a deposit or FS.
• No deposit bonus – one of the rarest options not offered by every casino brand. Customers don’t have to spend money to receive it.
• VIP/Loyalty bonuses – rewarded to the most valuable players who regularly stake on various online games and are members of the special club. Users accumulate points and then can exchange them for gifts and unique treats.
