Drac's Stacks

Count Dracula has been a slot character for decades, but rarely with this much going on behind the mirror. Drac's Stacks, released by Massive Studios on 6 December 2023, is a 5x6, 50-line game where stacked Mirror Symbols hide paying symbols, wilds or Vampire Bats - and the bats carry the prizes.

It remains a regular pick more than two years after launch. Juice's own games page listed $5.97M wagered across 2.7M bets over the 30 days to mid-October 2026.

Theme and design

The setting is Dracula's castle, played for laughs rather than scares: a cartoon Count, swarms of bats and tall stacks of mirror symbols. The mirrors are a clever fit for a vampire theme, since what they show is not necessarily what you get, and that idea runs through the whole mechanic.

How Drac's Stacks plays

The grid is 5 reels by 6 rows with 50 fixed paylines. Line wins are the base layer, as on any lines game. The second layer comes from the Mirror Symbols, which often land in stacks and then reveal what they are: a regular symbol, a wild, or Vampire Bats.

When mirrors turn into symbols or wilds, they feed straight into the paylines. When they turn into bats, the Bats feature starts, and that is where the instant prizes and multipliers come from.

Features in Drac's Stacks

Mirror Symbols

Mirrors are the key symbol. They land often stacked, and each reveals a regular paying symbol, a wild or Vampire Bats. A tall stack of mirrors turning into wilds can light up several paylines at once; a stack turning into bats starts the prize feature.

Vampire Bats

Every bat position picks one of several outcomes:

• Instant Prize: worth 1x to 5,000x the total bet.
• Multiplier: x2, x3, x5 or x10. Multipliers are added into a Total Multiplier, and the spot respins. At the end, the Total Multiplier applies to all instant prizes.
• Collector: gathers the prizes and collect values on screen, and the spots respin.
• Transform: in the base game, turns a whole reel into bats.
• Scatter or Super Scatter: counts towards the free games.
• Extra spins: in the bonus only.

The respins on multipliers and collectors are what make the feature build: each one opens space for another bat outcome before the round settles.

Free Games

Three scatters on reels 2 to 4, or two scatters plus one Super Scatter, award 8 free spins, and the scatters can also come out of the Bats feature. The bonus comes in two versions. In Free Games, bats can add +1, +2 or +3 spins, and the Transform covers two reels instead of one.

Super Free Games

Super Free Games is the stronger version. Here the bats can add +2, +3 or +5 spins, the Transform covers three reels, and the multiplier values step up to x3, x5, x10 and x25. The Total Multiplier is progressive through the round and applies to line wins as well as instant prizes, which gives the Super round the most potential.

Bonus buy and enhancers

The buy menu is fully priced:

• Enhancer 1: 2x the bet, five times the chance of the bonus.
• Enhancer 2: 10x the bet. Every bonus triggered is a Super Free Games round, and mirrors reveal only wilds or bats.
• Bonus Buy 1: 110x the bet for Free Games or Super Free Games, chosen at random.
• Bonus Buy 2: 500x the bet for Super Free Games with mirrors revealing only bats or wilds.

Availability of the buy and the enhancers depends on the casino and your jurisdiction.

Volatility and who it suits

Drac's Stacks is rated high volatility, and with a 50,000x ceiling that is no surprise. Instant prizes run from 1x to 5,000x before multipliers, so results vary enormously from one Bats feature to the next. The base game keeps things moving with line wins and mirror reveals, but the big numbers sit in the Super Free Games.

It suits players who like layered bonus features and a clear path from base game to big bonus. If you prefer a simple lines game, the number of moving parts may feel like a lot.

Our verdict on Drac's Stacks

Drac's Stacks is a dense, well-structured game. The mirrors give the base game constant reveals, the bats turn those reveals into a feature with real variety, and the Super Free Games add a progressive multiplier that reaches line wins too. A fully priced buy menu and a 50,000x ceiling round it out.

The RTP is the one point of confusion, with listings ranging from 96.5% to 96.74%. Check the game's info screen.
