The Library

Released in 2025, The Library is the first title from Kitsune Studios casino software, launched under the Hacksaw Gaming umbrella. 

The game introduces itself with a familiar mechanic—Stackways—which Hacksaw fans might recognize from earlier releases like Mayan Stackways or Ronin Stackways. 

Paired with a subtle nod to 'Book of' slots in the free spins round, this slot mixes familiar ground with a new visual direction. High volatility, a 10,000x max win, and a huge number of ways to win—up to 3.2 million—make this one worth checking out for players who enjoy feature-heavy gameplay with strong payout potential.

Theme and Symbols

Themed around a classic library, this game sets up shop in what looks like a cozy, book-filled study. It’s a calm, grounded environment—no flashy animations or elaborate fantasy worlds here. The reel symbols pull in some literary icons too, with stylized versions of famous figures like Dante and Poe among the high-paying symbols. 

Low-paying symbols are your standard 10 to A cards, while premiums are the four literary characters. A 5-symbol win on the low end gets you 0.5–0.6x your bet, while premiums pay 1.5–3x. It’s a setup that leans heavily on features to deliver the big wins, rather than line hits.

It’s a nice touch, even if the designs feel slightly AI-generated at times. Overall, the aesthetic is solid, if not overly inventive—more warm and familiar than groundbreaking.

Betting Options and Special Features

This online slot runs on a 5x4 grid and gives players up to 100,000 ways to win in the base game. In free spins, this can expand all the way up to 3.2 million ways. There are no wilds to help out, which is unusual, but the Stackways mechanic fills in the gap. Betting starts at 10 cents and goes up to $/€100 per spin, with an RTP of 96.34% and high volatility—so don’t expect small frequent hits.

The core of the game is Stackways. These symbols randomly appear and stack 2 to 10 matching symbols on a reel, but only if doing so creates a win. There are two types: normal Stackways (stack 2–4) and revealing Stackways (stack 5–10), and the stacked symbol is chosen to optimize potential wins from the current grid layout.

The free spins round—called Stack the Shelves Spins—is triggered by 3 scatters and comes with 10 spins. One regular symbol becomes the “Special” symbol, and if it lands on 3+ reels, it stacks and pays. Stackways can appear too, boosting the number of symbols on that reel even further. You can retrigger with +2 or +4 spins by landing 2 or 3 scatters, and hitting 4 scatters upfront upgrades the bonus to Super Stack the Shelves Spins, where two special symbols are active instead of one.

There’s also a Bonus Buy feature with multiple options: pay 3x your bet for bonus-boosted spins, 50x for guaranteed Stackways, or 150x to jump right into the Stack the Shelves feature.

Conclusion

For a first release by Kitsune Studios, The Library holds up well. It’s got a focused mechanic, decent math, and the kind of scaling win potential that will appeal to players chasing big hits. That said, the theme isn’t doing anything we haven’t seen before, and the lack of wilds may feel limiting to some. Still, if you're into Hacksaw's Stackways games—or like the idea of getting millions of ways to win from a library-themed slot—there's enough here to keep you spinning.

Fans of Mayan Stackways or Ronin Stackways will likely feel right at home, though The Library keeps things a little quieter in both visuals and atmosphere. It’s a good fit for experienced players who enjoy feature mechanics and aren’t reliant on wild-heavy setups, and it’s also approachable enough for newer players looking for something a little different.
