King Casino currently offers 20 Extra No Wagering Spins, which gives 20 spins on Big Bass Splash. The offer is aimed at new players, so it fits best if you are opening an account for the first time and want to try one specific game. To take part you need a minimum deposit of £20. The offer is valid for 7 days, and its wagering entry reads No wagering on winnings. The key terms are shown above, so the rest of this page explains what they mean in practice and where the offer may not suit you. T&Cs apply.
If you are comparing this offer with others, the two questions to ask are what you have to do with any winnings and how long you have to do it. The wagering entry answers the first question and the validity period answers the second. Read the full terms before you claim, because the summary above does not replace them. The sections below cover how the spins work, which mistakes can stop you getting value from them, and who should skip the offer.
How this bonus works in practice

Wagering is the number of times a bonus or its winnings must be played before they can be withdrawn. For this offer the wagering entry reads No wagering on winnings, which means winnings from the spins are not subject to a playthrough requirement. Many bonuses work the other way, where winnings have to be wagered before anything can be taken out, so this is the first difference to check when you compare offers. T&Cs apply.
The spins are limited to Big Bass Splash. They cannot be used on other slots, live tables or the rest of the games, so the game you choose is the whole offer. Because the choice is so narrow, the mechanics of that one game matter more than they would in a general promotion. Its paytable shows which symbols pay and by how much, its features explain how bonus rounds are triggered, and its RTP and volatility describe how it tends to pay over a long run.
Volatility is the easiest of these to misread. A higher volatility game usually pays in fewer, larger wins, while a lower volatility game tends to pay smaller wins more often. Neither the RTP nor the volatility predicts what a single session will return, because every spin is random. Treat them as background on how the game is built, not as a forecast.
The offer is valid for 7 days. That period is one of the key terms, so plan to use the spins within it rather than leaving them for later. Before you deposit, check that you know the eligible game, the minimum deposit and the time limit, and decide whether that game suits you. If you want a wider range of promotions, the bonuses section lists what King Casino offers across different types of bonus. T&Cs apply.

What can stop you getting value from it

The most common problem is missing the eligible game. The spins only work on Big Bass Splash, so opening a different slot first will not use them. Check the game name before you start, and go to it directly rather than browsing the lobby for a similar title.
The second problem is the time limit. The offer is valid for 7 days, which is a short window if you only play occasionally. If you are not likely to play within that week, the offer is not a good fit, and it is better to skip it than to rush through the spins. T&Cs apply.
The third point is the entry cost. The offer needs a minimum deposit of £20, so the spins are not separate from your own money. Only deposit an amount you can afford to lose, and do not add money to chase a result. You can read about how deposits work before you fund your account.
Finally, read the full terms before you deposit. The table above gives the main conditions, but the complete terms are where any other requirements are set out, and they apply to you whether or not you have read them.
Is it worth taking?

This offer suits a player who already wants to play Big Bass Splash, is ready to make the minimum deposit of £20, and can use the spins within 7 days. The no wagering on winnings term is its strongest feature, because it removes the playthrough step from any winnings the spins produce. For a player who knows the game and plans to play it soon, that is a clear advantage. T&Cs apply.
It is a weaker choice if you want a choice of games, a longer period to use the offer, or a larger package. The spins cover one game and a short window, and the deposit is needed before you can take part. If those limits matter to you, it is reasonable to skip this offer and look at what else is available.
Whatever you decide, the deposit is your own money. Only put in an amount you can afford to lose, and stop if the play stops being enjoyable. If gambling starts to cause you problems, the safer gambling page explains the support available.
