Different types of slots

Three reels slots

Three-reel slots are the original, classic slot machines. The idea, and the design, date from the age of mechanical gaming machines. This would originally have included features such as a side-mounted metal handle to spin the reels, giving you a chance to line up the symbols and gain a win.

Five reels slots

Digital technology and mass online access have revolutionised slot design. Unrestricted by physical space, modern slots now have five or even seven reels. That leaves plenty of room for more symbols per reel, bigger jackpots, and greater excitement.

Progressive slots

Progressive slots became available soon after the development of video slot games. Just like a lottery rollover, a progressive slot jackpot continues to increase until somebody wins a massive jackpot. Though a progressive jackpot can be limited to one slot machine, the idea has been harnessed to connect hundreds, if not thousands, of linked slot machine networks.


Multiplier symbols increase your winnings by a certain ratio. The amount of the increase varies according to the game rules. Some multipliers operate on regular game reels, while others only apply to particular features or bonus games.

Bonus games

Bonus games come in various forms, but all give you a chance to win extra money by playing a bonus feature game. You can qualify for a bonus game by completing a gameplay task. This then takes you into a ‘game within a game’ to earn your bonus. Some bonus games have elaborate storylines or complex features and demand specific skills, while others are straightforward.

Multi-payline slots guide

The first slot machines had just one pay line and lining up three identical symbols produced a win. However, today’s multi-pay line slots allow players to bet on many different pay lines. In multi-pay line environments, a win can often be achieved by lining up game elements in many directions, so it pays to be familiar with the game pay-out rules to understand your betting options.


Tips on playing slot games online

Make most of bonuses and promotions

Many online casino sites that offer slot games will also offer various and plentiful bonuses and promotions to ease you into the process of playing slot games.

Such bonuses and promotions can offer free spins, free multiplier increases and high jackpots – all benefits which will enhance your slot game experience and perhaps even your winnings.

Choose slots that fit your personality

The beauty of slots is their diversity and variety. There is a slot game out there for everyone and one tailored to every single type of player.

Do you want a relaxing experience with calming music? Are you full of energy and love a splash of colour and visual stimulation? Are you an opportunist – would a highly volatile slot offer you a more enriching experience?

Choosing a slot that matches your preferences can be critical to a successfully fun session in front of the reels. A slot that fits your personality is much more likely to be your friend and offer you what you are looking for, so take some time to look for the games that resonate with you.

Study the pay tables

Studying the pay tables will help you understand what combinations offer prizes, which symbols/lines to aim for, and if a game is ideal for you with your budget.

Check the pay tables

It is always essential to play within budget, and there are never exceptions. You should always set a budget before a session and ensure that you stick to that budget.

The danger of an open session with no set limits/boundaries is that upon landing on a losing streak, you can quickly lose track of the amount of money you have deposited and realise too late how much you have parted ways with.

Knowing when it is time to call it a day is the key to being a successful slots player. Setting a budget is the only consistent way to do this.

The most critical aspect of playing slot games is playing within your budget.

Online slots offer a much wider variety of slot games and even more opportunities to win.

Research the best online slots for an unlimited game inventory to suit your every mood, budget, and desire.

Aim for smaller jackpots

Slot games with smaller budgets tend to hit the biggest pay-out more often and offer you a greater chance of winning the maximum prize.

Unlike massive jackpot prizes that trigger once in a blue moon, smaller jackpot games have been known to pay out multiple times in one evening.

Scatter symbols

Scatter symbols can appear in any position on any reel. They are a reward feature which will gain you a win or allow access to another bonus feature – a free spins round, for instance. In most games, these are among the highest-paying symbols, which is why their design often reflects the slot game’s overall theme.

Total bet

This feature tells you how much your next gameplay will likely cost, including the bet total for each line and the number of lines you have chosen to bet on.

Volatility or variance

Volatility is a very important issue for slot players. Generally speaking, high-volatility slots give you bigger wins less often, while low volatility slots give you smaller wins but pay out more frequently. Low volatility slots are an excellent option for players whose budget is limited because they pay out little and often. Being reasonably predictable, they are also a good option for casual players.

Wild symbols

Think of a wild symbol as much like the joker in a pack of cards – they can be substituted for any other symbol and thus used to complete a winning line and gain a pay-out. Slots developers have tweaked the way wild symbols function in some slot games. So now you can take advantage of expanding wilds, shifting wilds, sticky wilds, cascading wilds, stacked wilds and more.



How do online slots pay-out?

Online slots pay-out when a player lines up winning symbols. While it varies from game to game, there are a certain number of pay lines and symbols that trigger a pay-out. This pay-out is based on the combination of symbols, the bet size, and the symbols’ value.

Winnings are paid out in cash to your account or in bet credits depending on any promotional offers.

Are online slots random?

Yes. Online slots are as entirely random as real slot machines. They pay out based on a random number generator, a programme that cycles through number combinations to determine the result of your spin.

When betting at William Hill, you can feel assured that your spin is thoroughly random and unpredictable. The house maintains an edge, but every slots player has the potential to experience wins, while big jackpots are frequently won online. At William Hill, we maintain a fair and equal platform for all players, and all illegal tactics found will immediately be stopped.

Is there a trick to slot machines?

There is no real trick when it comes to winning with slot machines. Many players will claim to have discovered a method that will boost their odds and winnings, but in reality, all slot machines are designed to pay out randomly and unexpectedly.

One way to enhance the odds of winning, programmed into the game by developers, is the theoretical return to the player above a specific number. It is worth checking which games offer this as it allows you to determine how many players have gone before and choose your moment to start spinning the reels.

Of course, it is not foolproof as slot machines are games of probability. Any factor that may alter probability will be programmed into the specific game, so is unlikely to ever drastically affect the results.

Are online slots rigged?

All slot games listed on William Hill’s website are hosted on licensed platforms and are certified by independent third-party authorities. There is no way William Hill can have any influence on how the games function or pay-out.

No rigging is involved with any games on the William Hill website. External developers design all games to be completely random and unpredictable.
