How to Play your UK Casino Bonus

Playing a casino bonus by best practice is not all that hard. You mustn’t give up after your first try. With our strategy, you will see results after playing half a dozen bonuses before you can see our strategy work.

The main thing is to have a bankroll to play your bonus with. It might be that you get unlucky on your first three tries due to spinning dead spins as we call it. This is when you will have no win at all and be one of those unlucky players that have an RTP of below 70%. Of course, this can happen, but with enough spins, you should be around 95% in RTP.

For those of you who are completely new to the online casino, RTP means a return to player and is the percentage of winnings or what you get back from your bets. The average of RTP on the slots we suggest you play is 96% or higher.

Follow these Quick Bonus Guidelines Before Starting

These are some quick guidelines you need to check before depositing and playing your casino bonus. All our casinos listed in the list check through these. You will at times find a casino that we have not listed so it’s then important they follow these important criteria.

  • Make sure the casino has a Gambling Commission License – You can find it at the footer of the page,
  • Check the wagering requirements of the bonus – Never play above 50X wagering on deposit and bonus,
  • Check the maximum bet – Some casinos have a maximum bet of the bonus, this is quite ok as long as it is not below £5,
  • Maximum Win – Some casinos have maximum win whilst playing a casino bonus – Stay away completely from them,
  • Check which games are excluded from wagering – Some casinos remove the possibility to wager on Table games and certain slots, this is quite ok as long as the list is not over extensive.

These are the simplest rules that you will encounter when playing your UK casino bonus. If you get a green light on all of them you are good to go.

Moving on to Playing your Casino Bonus

Once you have chosen the casino it is time to deposit. If your wallet allows it, you can always try to maximise your bonus. If a casino gives 100% up to £200, this means that you deposit £200 and play for £400. Most important in the beginning is that you get a decent win. We recommend playing medium volatility slot which can give you a medium-big win pretty fast: Reel Rush, Jack Hammer, The Invisible Man, Neon Staxx, Justice League or similar.

Some casinos give out the information of volatility on the slots which is a great guideline for players. Getting that win that triples your bankroll is crucial in the beginning so that you can simply move on to wager your bonus. We usually play 1.2% of our bankroll when moving on to a game and always change the game after hitting the bonus round or that big win.

Wager your Casino Bonus

When it is time to wager your casino bonus, we move on to less volatile slots. These slots are giving a lot of small wins on a lot of spins and to a lot of players. Some of these slots are restricted by online casinos so make sure you check the list which one you can play. If Blood Suckers from Netent is available, this is the first one you should go to. Low volatility and a high RTP of 98% makes this slot perfect for wagering.

Some casinos display the RTP so that all players can see them. One of those is Cashmio Casino. You can simply click the information button on your slot and check both volatility and RTP of the slot. Similar slots that are perfect to wager bonuses on are Starburst, Lights, Steam Tower and Stickers.

High Bets at the End to Maximise your Winnings

This is completely optional since it can mess up with your winnings big time. After finishing or nearly completing your casino bonus wagering, you can move on to high volatility slots to get one last Big Win before cashing out. We put this as optional as with volatile slots the chances of winning big are pretty slim. Slots like Wish Master, Dead or Alive or Gonzo’s Quest are perfect for this kind of gameplay. Hitting it big there at the end will secure many casino bonuses that you might play in the future.

Playing without a Casino Bonus

Those players who don’t like their money getting stuck in wagering requirements can, of course, play without a casino bonus. We are just like that and we call ourselves in and out players. We go in, play a pretty few spins on high bets compared to our bankroll and then cash out straight after a medium to the big win. The key to this is to cash out in time and not get greedy. Our sessions in this player behaviour usually round-up around 200-400 spins.

Example: Deposit £200 and we play £5 bets on reel rush or Neon Staxx. Hitting a bonus game usually puts us on a bit over £400 in the bankroll. At this time we always make a withdrawal of £400 doubling up our deposit and securing our sessions winnings. The leftover will go to the ultra volatile slot where our bankroll allows us to bet 20 spins pr. bankroll. Let’s say we have £60 left then we spin £3 bets on a pretty volatile slot like Dead or Alive.

This is all you need to know about playing casino with and without a casino bonus. Remember to have fun and most important don’t get greedy and cash out when you hit that wonderful BIG WIN.

History of Online Casino Bonuses

As we mentioned above, we will cover everything in this article around casino bonuses. We often wonder why online casinos give out casino bonuses to give players a bigger edge around the casino. Therefore we have asked these questions to the Casino Manager of Cashmio casino. We will keep interviewing Casino Managers through the year to gather their thoughts and strategies within the business. How they think the future of casino bonuses will evolve.

Gamification Casino Bonuses

A lot of the new casinos invest heavily in gamification, making the user experience much funnier in the casino. This means that the casino bonuses are usually lower and given after performing certain tasks within the casino. There are more loopholes where we can find value in optimising the gameplay at the casino.

Cashmio Casino, for example, has daily missions within the casino. Every day you have three missions that you can play within the casino. Playing these missions with minimum bet gives back around 100% of your bets. You will earn free spins or cash coins at this particular one. All you have to do after is wager the casino bonus according to our guide above and you are all set to get some value out of the casino.
