How Sound Design Affects the Players' Experience

Experts from the Rosloto company are glad to tell you about the features and benefits of using sound in online casinos. They will also discuss how the right music affects the audience's behaviour, contributes to its involvement, and increases the operator's profits.

About the Concept

This is the art of creating and customising sound effects, background music, and voice guidance that improve the gameplay, form a favourable environment, and have a positive effect on the emotions of customers.

Sound design is an important component of the user experience and contributes to the increase of retention indicators. Today, the solution is actively employed for land-based entertainment machines and interactive slots.

The main milestones in the tool's development in the gambling niche:

• 1895 — Charles Fey from the US invented the Liberty Bell casino product. It was supplemented with simple audible signals: the ringing of coins, clicks, and drumbeats during the reels spinning.
• 1963 — the Bally brand released the Money Honey electromechanical slot. It integrated familiar sound effects such as ringing, buzzing, and winning tunes.
• 1976 — Fortune Coin Company presented a solution with a built-in melody synthesis chip. Thanks to this, machines with several rhythms began to appear in the market.
• 1990s — the design of this kind became more sophisticated. Among the innovations, it is worth highlighting thematic soundtracks (like the noise of a spinning roulette wheel) and 16-bit music inspired by video games.
• 2000s — developers began to use digital effects. Music became adaptive: it could change depending on the phase of sessions and the punters' results. Microgaming, Playtech, Amusnet, and other software vendors became leaders in this field.

Basic Elements of Sound Design in Casino Entertainment

Let us consider what components modern developers use most frequently.

Musical Background

It creates a positive atmosphere on a gaming site and sets the mood (calm, exciting, or relaxing). A popular technique is the addition of a light lounge or jazz.

In slots, such tunes may differ depending on the theme of each product. Providers use oriental motifs in solutions aimed at an Asian audience, rock in dynamic slots, and arthouse in futuristic digital releases.

Poker and roulette are often complemented by classic melodies, which are never boring even during long sessions.

Sound Effects (SFX)

The most popular techniques in online casinos are the following:

1. The sound of the reels spinning. This is an important tool in slots since it imitates a real machine.
2. Clicks, flashes, fanfares, fireworks, and other signals. They enhance positive emotions in case of a victory, and prolong the joy and delight of a large prize or jackpot.
3. Interaction peals. They can be heard after pressing buttons and icons or when scrolling through the menu. Such options make the interface more responsive and understandable for the audience.

Voice Comments

In card games or roulette, dealers can vocalise the moves, thus creating a sense of being in an offline casino.

These hints increase gamblers' involvement and make the process of staying on the site more interesting. Even beginners who are not familiar with such entertainment will be able to understand its rules.

Slot machines often contain phrases that emphasise the success of clients:

• Big Win;
• Mega Jackpot;
• Good Luck and other commentary behind the scenes.

Providers also use animated characters that accompany the gameplay. They voice hints, help to complete difficult tasks, celebrate the victories of users, and encourage them in case of failure.

Winning Signals

These are short and memorable melodies. Most often, they are associated with luck and the reception of big prizes. The larger the reward, the more intense and solemn the sound becomes.

If people hit large jackpots, they can hear:

• fanfares;
• applause;
• fireworks;
• drums, etc.

Adaptive Sound

It changes depending on the situation during sessions, helping gamblers to better understand what is happening. A striking example is the acceleration of the melody when the bonus round is activated.

A change in tone attracts the clients' attention on a subconscious level, increasing their involvement and interest in the outcome of rounds. One of the trends is the use of neural network voices for instant adaptation to audience requests. For example, the pitch of comments can change depending on the customers' success.

Spatial Audio Design

It is used for navigating multiplayer entertainment or dynamic slots. Sound instruments help create the effect of presence in a real casino, which is especially important for iGaming platforms such as VR portals or solutions with live dealers.

The component enhances the immersive experience due to the in-your-face kind of sound. Thus, dice can fall in different places, and the roulette wheel may spin at several tables at once. Audio design ensures different audibility of all these melodies, as if the person is really in an entertainment location.

Psychological Impact of Sound on Gamblers

Music is extremely important for the formation of the right ambience in an online casino. It creates powerful incentives that increase the duration of sessions and encourage further placement of bets.

Let us consider how sound design affects the audience:

1. Emotional involvement. Musical backgrounds create an atmosphere of excitement and provide a feeling of deep immersion. Slow and soothing tunes can reduce tension, while dynamic ones, on the other hand, spark interest and make people want to continue playing. Slot developers often use this feature.
2. Enhancement of the reward effect. The sounds of triumphant notes (fanfare, coins, and applause) stimulate the release of dopamine, the pleasure hormone. Therefore, even small wins are always accompanied by such peals, creating the illusion of frequent victories. The addition of bright jingles makes users feel successful and special.
3. Creation of rituals and habits. Repetitive melodies (for example, the rotation of digital reels or the ringing of falling coins) become part of the routine. The effect is associated with the concept of a conditioned reflex. Gamblers begin to associate the selected sounds with pleasure and, as a result, return to the website more often.
4. Reinforcement of randomness. Such effects enhance the sense of predictability. This gives the illusion of control: clients think that they can “feel” the moment of a successful round.

How Music Affects Customer Retention

The operator's priority tasks are extending the sessions' duration, achieving the average game check, and making the LTV (Customer Lifetime Value) indicator higher. Competent sound design will make it easy to achieve the desired KPI metrics.

Background Melodies

Calm and unobtrusive tunes help the audience relax and spend more time in a casino.

In dynamic entertainment, the music becomes intense and accelerates, thus motivating users to make quick decisions:

• increase bets;
• replenish the account;
• purchase additional features to gain an advantage, etc.

Winning Sounds

Even if the gambler's reward is less than their initial stake, the accompaniment makes this victory meaningful and important.

A popular technique is to add a triumphant melody during “fake” wins (when the first bid can be higher than or equal to the final prize).

Sound Contrast

Important moments (for example, waiting for a bonus to appear) are followed by silence, which is then replaced by a sharp and loud tune. This creates the effect of surprise and holds the attention of casino visitors for a long time.

Adaptive Moments

This is a change in the musical arrangement depending on the person's actions. Thus, in bonus rounds, the melody becomes more intense and rich. It forms an impression of a “special moment”.

Trends in Sound Design for Online Casino Products

The latest tendencies in the development of content for iGaming platforms are:

1. High-quality realistic effects. Whispers, background conversations, and atmospheric noises are increasingly added to card and board games, creating a sense of presence. Providers also use studio recordings of real noises (such as coins, tokens, or roulette).
2. 3D sound. These are binaural beats that recreate the atmosphere of a real casino complex. Thanks to them, the melodies on virtual platforms are three-dimensional: they come from different directions and enhance immersion.
3. Personalisation. This is the ability to select and customise the sound design to the client's preferences. Many developers are also testing the capabilities of artificial intelligence to individualise tunes based on the interests and requests of players. It is expected that such an option will appear in online casinos very soon.
4. Cinematic arrangements. Most often, this is the addition of melodies from popular franchises, if the provider has previously received a licence to use the author's music.
5. ASMR effects. This is a whisper, a soft click, and light animation. They create a feeling of meditative gameplay that can quickly involve the audience and hold its attention for a long time.

Slots with the Best Musical Design

Let us consider products that have become popular with many gamblers from different parts of the world:

1. Gonzo's Quest. This series of video slots from the Swedish company NetEnt tells customers about the adventures of the Spanish conquistador Gonzo, who is looking for the lost city of El Dorado. The tunes here include the sounds of the jungle and falling stones, as well as other authentic melodies.
2. Immortal Romance. This is a vampire game with a deep storyline and atmospheric arrangements. Each character has a unique theme, and sound effects emphasise the mystical and romantic environment. The release was presented by the Microgaming European provider.
3. Viking Runecraft. Such digital entertainment from Play'n Go takes punters to the world of Scandinavian mythology with mysterious characters and huge payouts. The epic soundtrack uses traditional instruments and choral inserts, creating a feeling of grandeur and bright adventures.
4. Dead or Alive 2. This is a sequel to the popular Wild West-themed slot from NetEnt. There, people can hear the sounds of gunfire, creaking saloon doors, and a melody that immerses casino visitors in the world of fearless cowboys and wise sheriffs.
5. The Phantom of the Opera. Microgaming's product is based on the famous musical. The vendor added original tracks from the production and effects related to theatrical themes.
