Once Upon a Time Overview
Step into a storybook world with Play'n GO's Once Upon a Time, a visually charming online slot that weaves together elements from beloved fairytales. Released in 2014, this classic title has stood the test of time, offering a straightforward yet engaging gaming experience that continues to attract players who appreciate a well-crafted theme over complex, feature-heavy mechanics.
Game overview — official provider screenshot
The game is set against the pages of an ancient storybook, with symbols depicting iconic characters and items: you'll find a valiant Prince, a captive Princess, a cunning Witch, a fearsome Dragon, and magical items like a Rose and a spellbook. The audio complements the theme perfectly with a gentle, mystical soundtrack and satisfying sound effects that enhance the narrative feel.
This slot is ideally suited for Irish players who enjoy medium-volatility gameplay with a balanced pace. It's perfect for those who want a session with consistent, smaller wins and the potential for a rewarding bonus round, without the extreme swings of high-variance games. It’s also a great choice for fans of classic fantasy and fairytale themes.
Verdict: Once Upon a Time is a solid, reliable slot from a top-tier provider. While it may not boast the cluster pays or cascading reels of modern megaways slots, its strength lies in its charming execution, fair math model, and a rewarding Free Spins feature. It's a delightful choice for a casual spin when you're in the mood for a bit of storybook magic.
RTP, Volatility & Max Win
The game operates with a theoretical RTP (Return to Player) of 96.20%, which is above the industry average and aligns with Play'n GO's reputation for fair and player-friendly math models. This percentage indicates a good potential return over an extended period of play.
RTP and volatility breakdown view
Classified as a medium volatility slot, Once Upon a Time strikes a fine balance. You can expect a mix of smaller, frequent wins to keep your story going, punctuated by less frequent but more valuable payouts, typically triggered during the Free Spins feature. This makes it an excellent choice for players with a standard bankroll who want entertainment without excessive risk.
The maximum win potential is 2,500 times your stake. While not the colossal 10,000x+ seen in some newer titles, this is a very respectable top prize for a classic 20-payline game. Hitting the max win would require an exceptionally lucky combination of stacked high-value symbols during the Free Spins round with multipliers applied. It offers a tangible and exciting goal for your fairytale adventure.
Bonus Features & Free Spins
Once Upon a Time keeps its bonus structure elegantly simple, focusing on one primary feature that holds the key to the game's biggest rewards.
Theme, design and symbol layout
The Wild Symbol (Spellbook)
The ancient Spellbook acts as the game's Wild symbol. It can substitute for all other regular symbols to help form winning combinations across the 20 paylines. Landing multiple Wilds on a payline can also result in a win on their own. It appears on reels 2, 3, and 4.
The Scatter & Free Spins Feature (Magic Mirror)
The Magic Mirror is your key to the main event. Landing three or more Mirror Scatters anywhere on the reels triggers the Free Spins round. You'll be awarded an initial 10 free spins.
The magic happens during this round. Before each free spin, one regular symbol (excluding the Wild) is randomly chosen to become an expanding symbol. If enough of that chosen symbol land on the reels in a spin, they will expand to cover their entire reel, dramatically increasing the chance of big wins. Furthermore, all wins during free spins are subject to a 3x multiplier, which can lead to some truly royal payouts. The feature can also be retriggered by landing more Scatters during the round.
