Ariana Online Slot Overview

Ariana is a 5-reel video slot that takes you beneath the ocean waves with a mermaid-themed adventure. Developed by Microgaming (now part of Games Global), this online slot features 25 paylines and was released in May 2015.
Underwater and Mermaid Theme
The Ariana slot immerses you in an underwater world filled with ocean life and mythical mermaids. You’ll see symbols like dolphins, sharks, starfish, and colorful fish swimming across the reels. The main character is Ariana herself, a beautiful mermaid who serves as the game’s wild symbol.
The visual design brings the ocean floor to life with detailed graphics and a soothing color palette. The background shows an underwater scene with light filtering down from the surface. While the high-value symbols match the aquatic theme well, the lower-paying symbols use standard playing card icons (10, J, Q, K, A) in different colors.
Release Date and Developer
Microgaming launched the Ariana slot in May 2015. Microgaming is now part of Games Global, one of the largest developers in the online casino industry. The company has created hundreds of online slots over the years.
This game showcases Microgaming’s ability to blend engaging themes with solid gameplay mechanics. The developer designed Ariana to work smoothly on both desktop computers and mobile devices.
Game Type and Layout
Ariana is a standard 5-reel video slot with 25 fixed paylines. You can adjust your bet per spin from $0.25 to $250, making it suitable for both casual players and high rollers. The game has an RTP of 95.48% and medium volatility.
The slot includes several features:
- Wild Symbol: Ariana expands to cover entire reels
- Scatter Symbol: Triggers the free spins bonus
- Free Spins: Activated by landing three or more scatter symbols
- Expanding Wilds: During free spins, wild symbols expand more frequently
The controls are user-friendly, with options for regular spins and autoplay mode.
Symbols and Special Features

Ariana features a well-designed symbol set that works together with several special mechanics to create winning opportunities. The game’s wild and scatter symbols interact with the expanding symbol feature to deliver its most significant payouts.
Wild Symbol and Stacked Symbols
The Ariana logo serves as the wild symbol in this game. It substitutes for all regular symbols except the starfish scatter to help complete winning combinations. You’ll find this wild appearing on reels 2, 3, 4, and 5.
Stacked symbols are a key part of the game’s mechanics. When symbols stack fully on the first reel, they trigger the expanding symbol feature on other reels. This applies to both regular symbols and high-value symbols like Ariana herself, treasure chests, and coral reefs. The stacked symbol mechanic creates opportunities for expanded wins across multiple reels at once.
Starfish Scatter and Scatter Wins
The starfish acts as the scatter symbol in Ariana. You need three or more starfish symbols anywhere on the reels to trigger the free spins bonus round. Unlike regular symbols, scatters don’t need to land on specific paylines to award prizes.
Landing three or more starfish scatters awards 15 free spins. The scatter symbols pay based on the total number appearing on screen, regardless of position. During the base game, scatters contribute to your overall winnings while also serving as the gateway to the bonus feature.
Expanding Symbols and Expanding Wilds
The expanding symbols feature activates when you land a full stack of matching symbols on reel 1. When this happens, all matching symbols on reels 2, 3, 4, and 5 expand to fill their entire reel. This creates substantial winning potential across multiple paylines simultaneously.
During free spins, the expanding mechanic becomes more powerful. Any high-value symbol appearing on the reels can expand, not just those stacked on reel 1. This means you have increased chances for full-screen symbol coverage during your 15 free games. The expanding wilds don’t function separately from regular expanding symbols but follow the same expansion rules when part of a stacked set.
Free Spins and Bonus Rounds
The Ariana slot offers a straightforward bonus system centered around free spins that activate through scatter symbols. During these rounds, expanding wilds boost your winning potential significantly.
Triggering 15 Free Spins
You need to land three or more starfish scatter symbols anywhere on the reels to activate the free spins feature. This awards you 15 free spins automatically.
The starfish scatter symbols don’t need to appear on adjacent reels or specific paylines. They can land in any position across the five reels. This makes triggering the feature more achievable compared to slots with stricter scatter requirements.
Once activated, your 15 free spins play at the same bet level and payline configuration you used on the triggering spin. You don’t need to place additional bets during the free spins round.
Retriggering the Free Spins Feature
You can retrigger the free spins feature while already playing your free spins. Landing three or more starfish scatter symbols during the bonus round awards another 15 free spins.
These additional free spins add to any remaining spins you have left. If you retrigger with 5 spins remaining, you’ll have 20 total spins to complete. There’s no stated limit on how many times you can retrigger the feature during a single bonus round.
Expanding Wilds During Free Spins
The Ariana logo wild symbol expands to cover entire reels during free spins. When the wild lands on reel 1, it stretches to fill all three positions on that reel.
This expansion creates more opportunities for winning combinations across multiple paylines. A full reel of wilds can connect with matching symbols on other reels to form several wins simultaneously.
The expanding wild mechanic only activates during free spins, not during base game play. This makes the bonus rounds significantly more valuable than regular spins.
Bonus Rounds Mechanics
The slot uses a single bonus round structure focused entirely on the free spins feature. There are no pick-and-win games, wheel spins, or multi-level bonus stages.
During free spins, all wins count at the standard paytable values. You don’t receive multipliers on your wins, but the expanding wilds compensate by creating more winning combinations. The medium volatility means you’ll see a mix of smaller and larger wins throughout your 15 spins rather than just one or two big payouts.
Gameplay Mechanics and Controls
Ariana operates on 25 fixed paylines across five reels, giving you multiple ways to land winning combinations with each spin. The game includes standard controls for adjusting your bet size and activating automated play features, while sound settings let you customize your audio experience.
Paylines and Ways to Win
The game uses 25 paylines that remain active on every spin. You can’t adjust the number of active paylines, but you can control your total bet by changing the coin value and number of coins per line.
Winning combinations form when matching symbols land on active paylines from left to right. The paytable shows exactly how much each symbol combination pays based on your current bet level.
You can set your coin size between $0.01 and $5, and wager up to 10 coins per line. This creates a betting range from $0.25 to $125 per spin, making the game accessible for different budget levels.
Autoplay and Quickspin Features
The autoplay feature lets you set the reels to spin automatically for a predetermined number of rounds. You can typically choose from options like 10, 25, 50, or 100 automatic spins.
Most versions include advanced autoplay settings where you can set loss limits or win limits that stop the feature when reached. You can also configure the autoplay to stop on any win or when the free spins bonus triggers.
The game doesn’t have a dedicated quickspin button, but the standard spin speed keeps gameplay moving at a steady pace without unnecessary delays between rounds.
Sound Settings and Customization
You can access sound settings through the game’s menu or settings panel. The controls let you adjust or mute both the background music and sound effects independently.
The underwater soundtrack plays continuously during regular spins and intensifies during winning combinations and bonus features. If you prefer a quieter experience, you can turn off the music while keeping sound effects active, or mute all audio completely.
These settings save your preferences for future sessions at most online casinos that host the game.
Betting Options and Payouts
The Ariana slot offers a wide betting range and clear payout structure. The game uses fixed paylines and straightforward multipliers that make calculating potential wins simple.
Bet Sizes and Max Bet
You can place bets starting at 25p per spin, which makes the game accessible if you prefer low-risk play. The max bet reaches £500 per spin, accommodating players who want to wager larger amounts.
The game features 25 fixed paylines across 5 reels and 3 rows. This means every spin covers all paylines, and your total bet is divided across these lines. You can adjust your bet using the stacked coins icon below the spin button. The wide range between minimum and maximum bets gives you flexibility to match your budget and playing style.
RTP, Volatility, and Top Win
The game has an RTP of 95.48%, which sits below the industry average of 96%. This means the slot returns roughly £95.48 for every £100 wagered over extended play.
Ariana features medium volatility. This suggests you should see wins at a moderate frequency with payouts that balance between small and medium-sized amounts. The maximum win reaches 240x your stake. While this top win is modest compared to high-volatility slots, it can become significant at higher bet sizes. A max bet of £500 would result in a top prize of £120,000.
Wagering Requirements
Wagering requirements apply when you play Ariana with bonus funds at online casinos. These requirements determine how many times you must wager bonus money before withdrawing winnings.
Most casinos count slot games at 100% toward wagering requirements. Check your casino’s terms to confirm that Ariana contributes fully to these requirements. Your bets on this game should help clear bonus requirements efficiently since slots typically offer the best contribution rates.
Playing Ariana Online: Real Money and Demos
Ariana is available in both free demo mode and real money versions at online casinos. You can test the game without risk before committing your bankroll, and the slot works smoothly on both mobile devices and desktop computers.
Free Play and Demo Versions
You can access Ariana’s demo version without downloading software or creating an account. The free play mode gives you virtual credits to explore all game features, including the expanding symbols and free spins bonus round.
Demo mode lets you practice bet management and understand the game mechanics before risking real money. You’ll experience the same RTP of 95.48-95.50% and all 25 paylines as the real money version. The only difference is that you can’t withdraw any winnings from demo play.
Many casino review sites host the Ariana demo directly on their pages. This means you can start playing within seconds without registration requirements.
Mobile and Desktop Experience
Ariana runs on both mobile and desktop platforms without performance issues. The game uses HTML5 technology, so you can play directly in your browser on smartphones, tablets, and computers.
The mobile version features user-friendly controls adapted for touchscreens. All buttons are sized appropriately for finger taps, and the interface adjusts to fit different screen sizes. You can set your bet amount, spin the reels, and activate autoplay with simple gestures.
Desktop players get the same gameplay with larger visuals and more screen space. The controls remain straightforward regardless of which device you choose.

Theme, Graphics, and Sound Experience
Ariana takes you beneath the ocean’s surface into a mermaid’s realm filled with sea creatures, treasures, and vibrant coral formations. The game combines polished visuals with calming audio to create an immersive underwater adventure.
Visual Elements and Animation
The game displays five reels against a deep blue ocean backdrop that mimics the look of being underwater. You’ll see gentle animations throughout gameplay, including swaying seaweed and glowing coral reef formations that add movement to the scene. The graphics maintain a high-definition quality that keeps the underwater theme consistent.
The visual design focuses on a mystical ocean atmosphere where light filters through the water. Ariana herself appears as a stacked symbol on the reels, rendered with detailed artwork that makes her stand out from other icons. When you land winning combinations, the symbols light up with brief animations that highlight your wins without overwhelming the screen.
The color palette uses shades of blue, purple, and teal to reinforce the ocean setting. Each spin reveals polished graphics that work well on both desktop and mobile devices.
Audio and Music Setting
The soundtrack features soothing, ethereal music that matches the underwater theme. The audio creates a relaxing atmosphere during regular spins, then increases in intensity when you trigger wins or activate bonus features.
Sound effects include gentle water sounds and chimes that play when symbols land on the reels. You have access to sound settings that let you adjust or mute the audio based on your preferences. The music maintains a calm pace that suits longer play sessions without becoming repetitive or distracting.
Notable In-Game Symbols
The symbol set includes both thematic and standard icons. Ariana serves as the highest-value symbol and appears stacked on the reels. You’ll also encounter a treasure chest and dragon-like sea creatures as premium symbols.
The starfish acts as the scatter symbol, appearing in bright colors that make it easy to spot. Lower-value symbols use playing card ranks from 10 through Ace, designed with a decorative ocean style. The Ariana logo functions as the wild symbol, substituting for most other icons to help create winning combinations across the 25 paylines.
Frequently Asked Questions
Players often have questions about slot mechanics, bonuses, and fairness when choosing games like Ariana. Understanding payout rates, security features, and participation options helps you make informed decisions about your gameplay.
How can I increase my chances of winning on casino slot games?
You cannot change the outcome of individual spins since slots use random number generators. However, you can manage your bankroll wisely by setting limits and sticking to them.
Choose games with higher RTP percentages, like Ariana’s 95.48%, as these return more to players over time. Playing all available paylines also ensures you don’t miss winning combinations.
What bonuses are available in popular online slot games?
Most online slots offer free spins rounds that activate when you land specific scatter symbols. Ariana includes a free spins feature with expanding wild symbols that can create larger wins.
Wild symbols substitute for other symbols to complete winning combinations. Some games also feature stacked symbols that fill entire reels, increasing your chances of multiple wins on a single spin.
Bonus rounds may include pick-and-win games or multipliers that boost your payouts. The specific bonuses vary by game, so you should check the paytable before playing.
Are there any strategies for playing progressive jackpot slots effectively?
Progressive jackpot slots typically require maximum bets to qualify for the top prize. You need to check the specific requirements for each game before playing.
Set a strict budget since progressive slots often have lower base game RTPs than regular slots. The reduced return compensates for the large jackpot potential.
Play during off-peak hours when fewer players are active, though this doesn’t change your actual odds. Remember that progressive jackpots are extremely rare wins based purely on chance.
What are the typical payout rates for top-rated online slots?
Most reputable online slots have RTPs between 94% and 97%. Ariana offers an RTP of 95.48%, which falls in the middle of this range.
RTP represents the theoretical return over millions of spins, not your individual session results. A 95% RTP means the game returns $95 for every $100 wagered over the long term.
You can usually find RTP information in the game’s paytable or help section. Licensed casinos are required to display this information for player transparency.
How do online slot tournaments work and how can I participate in them?
Slot tournaments give you a fixed amount of credits and a set time limit to accumulate wins. Your total wins determine your ranking on the leaderboard.
You typically pay an entry fee to join, though some casinos offer free tournaments for registered players. Prizes go to the top finishers based on their final scores.
Check your casino’s promotions page to find available tournaments. You’ll need to register before the start time and be available during the tournament window to compete.
What are the security measures in place to ensure fair play in online slot games?
Licensed online casinos use random number generators that are regularly tested by independent auditors. These RNGs ensure each spin’s outcome is completely random and cannot be predicted or manipulated.
Reputable gaming authorities like the Malta Gaming Authority and UK Gambling Commission require regular audits. Game providers like Microgaming, which created Ariana, must meet strict fairness standards.
You can verify a casino’s licensing information in the footer of their website. Look for certifications from testing agencies like eCOGRA or iTech Labs that confirm game fairness.
