Temple Stacks Online Slot Review and Demo Guide
Yggdrasil’s Temple Stacks gives players from 243 to 832 ways to win. Its reels feature ‘Splitz’ mystery stacks, re-spins, a hybrid sticky wild and scatter, and free spins. It is Yggdrasil’s first slot with Splitz mechanics.
Theme and Story Line
The game is set in a South American jungle during the Aztec era, where the reels spin among relics and symbols from the ancient Aztec Empire.
Graphics, sound and animation
Temple Stacks was one of Yggdrasil’s latest slot releases in 2020. The developer’s 3D artwork and animation expertise supports smooth play on mobile and desktop, and is evident here. The reels shift as you spin, accompanied by detailed artwork, softly beating drums and distant Aztec instruments.

Top Casinos to Play Temple Stacks:
Gameplay
Temple Stacks has a 5x3 reel layout, though it can change on any spin. The number of ways also varies, from the standard 243 ways to a maximum of 832. There are no paylines: matching symbols can land anywhere on the reels, provided they meet the 2 rules used to calculate wins.
- The combination must start with its first symbol on reel 1
- Each subsequent symbol must appear on an adjacent reel
As a result, combinations run from left to right. A 4-symbol win, for example, needs the same symbol on reels 1-2-3-4. If it lands on reels 1-2-3-5 instead, it counts as a 3-symbol combination because reel 4 has no matching symbol.
Splitz mystery stacks, re-spins and free spins can all help create winning combinations. The menu opens a paytable with 10 regular paying symbols. The top symbol is the red square, paying 50 coins for 5 in a row.
To see the paytable in cash rather than coins, open settings and switch off ‘Display values in coins’. The same section offers detailed sound controls and autoplay strategies, including conditions for stopping auto spins.

Bonuses and Free Spins
Splitz Mystery Stacks: A Splitz symbol can split into 12 matching symbols anywhere across the reels. These extra positions increase the number of ways to win, helping form 4- and 5-symbol combinations and multiple combinations at once.
Hybrid-Wild/Scatter: This symbol is both a wild and the scatter for free spins. When 2 land on the reels, it acts as a wild and triggers re-spins; 3 symbols start the free-spins round.
Re-spin: In Temple Stacks, Evan Carrington explains that landing 2 hybrid wild/scatter symbols triggers a re-spin. Both 2 wild symbols remain on the reels as sticky wilds for the duration of that re-spin.
Free Spins: Land 3 hybrid wild/scatter symbols to trigger free spins. Landing 3, 4 or 5 starts the bonus game and adds 20, 200 or 2,000 coins, respectively, to the accumulated free-spin bonus winnings. Choose from 4 free-spin levels; the number of free spins depends on how many hybrid wild/scatter symbols land.
Here are the available choices for 3/4/5 scatters:
- Steel: 15/20/35 free spins with 3 – 9 Splitz mystery stacks
- Bronze: 9/12/21 free spins with 4 – 10 Splitz mystery stacks
- Silver: 6/8/14 free spins with 5 – 11 Splitz mystery stacks
- Gold: 3/4/7 free spins with 6 – 12 Splitz mystery stacks
The same combinations listed above can also retrigger the free-spins feature.
Bet Sizes, RTP and Variance
The ‘Coin Bet’ box fixes the spin at 20 coins. Adjust the cash stake by changing the ‘Coin Value’ box, which ranges from 0.005 to 1.00.
- Minimum Bet: 0.005 cash per coin x 20 coins = 0.10
- Maximum Bet: 1.00 cash per coin x 20 coins = 20.00
Yggdrasil lists this slot’s theoretical RTP as 96.1%, split between 59.1% Base Game RTP and 37.0% Free Spins RTP. The supplied review also describes the variance as medium to high; this is an opinion, not a promise of results.
Conclusion
The review presents Temple Stacks as a distinctive online video slot from Yggdrasil. Its changing grid ranges from 243 to 832 ways to win, while the Splitz Mystery Symbol can add positions for larger combinations. The hybrid wild/scatter and choice of 5 free-spins rounds bring further variety, making Temple Stacks worth considering for players after a different format.
