Winning Slots Guide.

Is there a strategy to win?

This is a question many players ask themselves every time they fire up the online casinos, is it possible to turn the odds to your own advantage?

The answer is yes!

1 Bankroll Management

Online slots games are quite unique in themselves where one slot can play and pay completely different to another.

There is a method to play within reasonable stakes to your Bankroll, for example it’s not advisable to play £10 spins on a high variance slot like Rgaing Rhino with £200 Bankroll, as the slot pays at very limited intervals.

What we mean by this is Variance, one slot can pay enormous pays but at very few intervals, so the wait for a hit may be 100s of spins, while others pay out smaller wins at far more regular intervals.

We can class these games as High Variance Slots and Low Variance slots.

The most effective strategy with is to play the High Variance slots on lower bets to allow you a better chance for that mega win.

And the low variance slots play on bigger stakes for the more regular wins.

2. Free Play Slots

Take some time trying out the Slot games on demo and free play mode to get used to the dynamics of the game.

Make sure you hit the bonus rounds to try out all the different options (many slots have different bonus round picks).

By trying out the slots you can learn which is the high variance and low variance games, make sure to lower the bet in the high variance games.

Try out our 1400 Free Play Slots Here.

3. Return To Player RTP

Each individual slot is unique and has its own algorithm (random generator), when choosing what slot to play there can be a few points to consider.

However the number 1 has to be the Return to Player %, most online slots vary from 92% – 99%, anything less than this you should really look to avoid (unless it has a progressive jackpot you want to chase).

Here are some of our Favourite Super High Variance games where 1000x Stakes can hit pretty often

  1. Raging Rhino 95.91% RTP
  2. Dead or Alive 96.80% RT
  3. Break Da Bank Again 95% RTP
  4. Reel Steel 95.90& RTP
  5. Book of Dead 96.21% RTP

Here is the list of our top 5 Lower Variance slots, excellent when you have a deposit bonus to wager through.

  1. Steamtower 97% RTP
  2. Wonky Wabbits 96.50% RTP
  3. 1429 Uncharted Seas 98.60% RTP
  4. Blood Suckers 98% RTP
  5. Big Bad Wolf 97.34%

4. Deposit Bonuses

When making a deposit especially as a new player the online casinos will offer you an incentive, mainly matched deposit offers.

These all come we an attached wagering requirements and max bet levels, you should read fully the terms to make sure you don’t breach them.

The wagering can be an multiple of the matched amount you receive or a combination of the Deposit + Bonus.


Deposit £100 Bonus £100  Casino require 50 x the bonus amount in wagering = £5000 to wager.

Deposit £100 Bonus £100 Casino require 20 x the bonus + deposit in wagering = £4000 to wager.

Bonuses can be great value as they allow you to play at higher stakes with free money, however the wagering can be tough to beat and the choice of slots can make of break your balance.

Check out our Free Slot Game of the week, those crazy WONKY WABBITS, provided by NETENT, 96.5% Return to Player RTP.

This is a wacky 5 reel 14 payline slot, with a bonus feature built in to the base game. The wild symbol replicates on the reels and position itself in the best position possible. The wild symbols are stacked on reels two and four and its possible to get a full screen of wilds paying a huge 1500x your stake. This is a fun game and a lot of slot players recommend completing wagering on it. If you fancy a quick spin of the reels of the game just click the picture and you can try it in free play. It certainly checks in as one of our Best UK Slots Free at SlotWinner Uk.

Grosvenor Casino Review

Independent Casino Reviews Grosvenor


Grosvenor online casino has been live since 2001 and is part of the Rank Interactive group which started operations circa 1937. Since partly to the takeover of Gala in 2013 Grosvenor has become the largest land based operator in the UK and is one of the most recognisable brands around operating well over 50 casinos.

The internationally renowned IGA gaming awards announced Grosvenor to be operator of the year in 2013

The site itself offers a no download casino, with a smooth interface and mobile/tablet compatibility.

Slot Games

Grosvenor offers a huge selection of providers to include WMS, IGT and hard to find NOVOMATIC games which offer some really superb high variance slots. In total there are over 250 slots to choose from and we found that the servers were fast and responsive and we didn’t experience any crashes. We would recommend trying out PHAROH’S TOMB or BEETLE MANIA which are pretty hard to find slots for UK based players and very offer some real mega win potential.

Live BlackJack and Roulette

Grosvenor online casino offers its own poker games, both video poker and table online poker, a selection of online blackjack games as well as the opportunity to bag one of its many progressive jackpots. There is also a very wide selection of live roulette games where you can chance your arm against the live wheel.

Many variations of arcade games, such as Deal or No Deal, Virtual Horses, and Bouncy Balls. Video poker games include Multi-Hand, 3 Card Brag, Triple Play Draw Poker and Game King Jacks or Better.

The rich assortment of card and table games includes various blackjack variants, such as Perfect Pairs Blackjack, Hi Lo Blackjack, and Vegas 3 Hand Blackjack. You can enjoy the land-based Pinball Roulette online, as well as other forms of what is the most popular table game in the world. Try your luck at Classic Roulette, Double Bonus Spin Roulette, or Real Deal Roulette.

Bonus and Loyalty Programme

As a land, based casino member, you can receive £20 FREE without depositing one penny, all you need to do is follow the link above or below and Simply enter your membership details on the registration page, once you have registered via SlotWinner.co.uk you will receive £20 into your account, with no deposit needed.

If you are not a land based member there is still an incredibly low wagering bonus of £20 matched deposit with only 5x wagering attached, this gives you a great chance of cashing those winnings.

As you play at Grosvenor you will accumulate play points these can also be earnt at the land based properties. Points are made at 1 comp point for every £10 wagered and 100 comp points = £1

These points can be redeemed for many goodies which range from free spins to IPADS and luxury holidays. The reward program seems very generous with a great varied selection of gifts.


Grosvenor has some of the most popular banking methods for both withdrawing and depositing. Debit cards including Visa/MasterCard, credit cards the same. E-wallets Neteller Skrill and PaySafe. But one great addition is they are one of the very few online casinos offering PAYPAL for both withdrawal and depositing which is a great bonus in my opinion

Withdrawal Times vary, for E-wallets it is normally within 24 hours, but debit cards can take until 72 hours


We at Slot winner UK find overall  Grosvenor a very solid site with a monster reputation and umbrella firm behind it, having some rare slot providers especially for the UK market makes the game play fun and entertaining. The cashier has many options and normally processes in 48 hours makes this a go to online casino for integrity and game play, try it out.

Casumo is one of the market leader and offers a huge selection of games, the reward and loyalty system is unusual and some may prefer other options. However this site is leading the way in customer support and trustworthiness and must be near the top of any online players list and I must admit this is in my personal  top 3 of online casinos it really offers everything you want as a player.

Here at Slot winner Uk we find that the site is very smooth and easy to navigate with a live customer support service, the game severs are fast with no discernible lag .

New players at 21 Casino can enjoy 21 free spins on Starburst as soon as they register a new account – no deposit necessary. This 21 theme is carried on throughout the site in the promotions page, while more lucrative bonuses are also available on first, second and third deposits to give plenty of free cash for new players.

The live casino allows players to play games against live dealers. Here you can select from various types of roulette and blackjack and play via video linkup to feel the excitement of a live casino from the comfort of your own home.
