Slot review: Once Again Upon a Time

Once Again Upon a Time is a Betsoft fairy tale sequel that drops you right back into the classic setup: a brave knight, a princess in trouble, and a dragon that looks like it owns the whole kingdom. The vibe is storybook and colorful, but the gameplay is more “feature hunting” than cozy spinning. Most of the base game is standard line wins with a twist from stacked mystery spots that can suddenly turn a dull spin into something decent. The real reason you stay is the Hold and Win side of things. It feels like the game is constantly teasing it, then making you work for it.

Slot overview: Once Again Upon a Time

This slot uses a 5 reel, 3 row layout with 25 fixed paylines. Betsoft lists the RTP at 96.11%, with very high volatility and a 23.67% hit rate on the official page. The commonly listed bet range is around 0.25 to 30, and the maximum win is reported up to 12,285x.

Main mechanics include Stacked Mystery Symbols, Free Spins, Hold and Win, a BOOST symbol that increases bonus values, and a Buy Bonus option.

Slot features: Once Again Upon a Time

Wild: Wild substitutes for all symbols except Bonus, Boost, and Scatter.
Stacked Mystery Symbols: Each reel includes stacked mystery positions. Before a spin, those mystery spots are replaced with one random symbol, and all mystery spots use the same symbol for that spin. This can suddenly stack a premium symbol or helpful filler across the reels.
Free Spins: Landing 3 Scatter symbols awards 8 Free Spins. During Free Spins, only high paying symbols appear on the reels, so the feature is less about small drips and more about trying to land a few stronger hits.
Hold and Win Feature: Trigger by landing 6 Bonus symbols, or 5 Bonus plus 1 Boost. You start with 3 respins. Bonus symbols are the ones you want locked on the grid, and Boost is the one that pushes their values higher.
Boost: Boost only matters for Hold and Win. If it lands as part of the trigger, it increases the values of the Bonus symbols on the reels.
Mystery Bonus: This symbol can appear during Hold and Win and turns into a random prize type: Mini, Minor, Major, Mega, or Boost. It is basically the feature’s wild card, because it can upgrade what you already have on screen.
Royal Fortune: In the base game and in Free Spins, any Bonus symbol that lands can give a chance to win extra Hold and Win rounds. It is like a little “surprise door” into the main feature.
Buy Bonus: The game includes a Buy Bonus button for instant access to the Hold and Win feature with 3 respins. Commonly listed at 65x the bet.

Our verdict: Once Again Upon a Time

This feels like a slot with a good feature core, but a base game that can run out of charm quickly. The stacked mystery positions keep normal spins from being totally flat, and Free Spins having only premium symbols is a nice change of pace. But the experience still revolves around Hold and Win, and if that feature does not show up often, the session can feel like you are just spinning through the same chapter again and again. When Hold and Win lands with Boost and a Mystery Bonus swing, it can be genuinely fun. Still, the very high volatility plus possible lower RTP versions mean it is not always the most rewarding fairy tale to replay.

Our rating 4.5/10
