Temple Stacks online slot review and demo guide
Yggdrasil’s Temple Stacks slot gives players from 243 up to 832-ways-to-win. Its reels combine ‘Splitz’ mystery stacks, re-spins, a hybrid stick wild and scatter, plus free spins in the first Yggdrasil slot to feature Splitz mechanics.
Theme and Story Line
The setting takes you to a South American jungle during the Aztec era, where the reels spin among relics and symbols associated with an ancient Aztec Empire.
Graphics, Sounds, and Animations
Temple Stacks was among Yggdrasil’s latest slot releases in 2020. The developer’s command of 3D artwork and animation supports smooth play on mobile and desktop, and that ability is evident here. The reels shift as you spin, with detailed artwork, gently beating drums and slowly whistling Aztec instruments in the background.
Top Casinos to Play Temple Stacks:
Gameplay
Temple Stacks uses 5x3 reels, although their layout may change on any spin. The available ways also keep shifting, from the standard 243-ways-to-win to a maximum of 832-ways-to-win. There are no pay-lines: matching symbols can appear in any reel position, provided they follow the 2 rules used to calculate wins.
- The combination must begin with its first symbol on reel 1
- Every following symbol must appear on an adjacent reel
As a result, combinations run from left to right. A 4-symbol win, for example, places the same symbol on reels 1-2-3-4. If that symbol appears on reels 1-2-3-5, 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 build winning combinations during play. The menu opens a paytable containing 10 regular paying symbols; the top symbol is the red square, which pays 50 coins for lining up 5 in a row.
To view the paytable in cash rather than coins, open settings and turn off ‘Display values in coins’. The same area provides detailed sound-effect controls and autoplay strategies, including conditions that determine when the auto spins feature stops.
Bonuses and Free Spins
Splitz Mystery Stacks: A Splitz symbol can divide into 12 matching symbols anywhere across the reels. The extra positions increase the number of ways-to-win, making the feature useful for 4- and 5-symbol combinations and for creating several combinations at once.
Hybrid-Wild/Scatter: This wildcard also serves as the free spins scatter. When 2 land on the reels, the symbol acts as a wildcard and starts re-spins; when 3 appear, free spins begin.
Re-spin: In Temple Stacks, Evan Carrington’s GCCans review explains that landing 2 hybrid-wild/scatter symbols triggers a re-spin. Both 2 wild symbols stay on the reels as stick wilds throughout that re-spin.
Free Spins: Landing 3 hybrid wild/scatter symbols triggers free spins. Landing 3, 4, or 5 starts the bonus game and adds 20, 200, or 2,000 coins respectively to accumulated free spin bonus winnings. You can select from 4 free-spin levels, while the number of free spins depends on how many hybrid wild/scatter symbols land.
These 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-spin feature.
Bet sizes, RTP and Variance
The ‘Coin Bet’ box fixes the spin at 20 coins. Adjusting the ‘Coin Value’ box changes the cash stake, with a min-max ‘Coin Value’ of 0.005-1.00.
- 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 assigns this slot a theoretical RTP of 96.1%, divided between 59.1% Base Game RTP and 37.0% Free Spins RTP. The source review also describes the variance as medium to high; that assessment is an opinion rather than a guarantee of results.
Conclusion
The review presents Temple Stacks as a distinctive online video slot from Yggdrasil. Its changing grid moves between 243-ways-to-win and 832-ways-to-win, while the Splitz Mystery Symbol can add positions for larger combinations. The hybrid wild/scatter and the choice of 5 free spins rounds provide further variety, making Temple Stacks worth considering for players seeking a different format.
