- A very unique game from popular developer BTG
- 3D rotating tower allows wins around the edges
- Takes some getting used to but it’s surprisingly fun
Big Time Gaming breaks the mold with Crystal Towers, a visually inventive 3D slot that abandons traditional reels in favor of a rotating cube tower. Played on a floating island, the game challenges players to form cluster wins on a 5-row grid that can grow into 10 during bonus rounds.
With high volatility, a 96.36% RTP, and a 36,085x max win, this slot offers both stunning presentation and serious payout potential. The Match 5 cluster mechanic, cascading wins, and rotating tower add puzzle-like strategy to every spin, especially as the game transitions into an expansive free spins feature.

Crystal Towers Slot Bonuses and Features
Match 5 Cluster Wins. Wins are triggered by matching at least five adjacent symbols, horizontally or vertically. Winning clusters disappear, triggering a chain reaction as symbols fall and new ones appear. What sets this apart is the 3D rotating tower, which allows matches to wrap around edges.
Wild Types. Crystal Towers includes three types of Wilds, each with unique functionality:
- Regular Wilds – Substitute for any adjacent pay symbol except Multiplier and Trigger Wilds.
- Multiplier Wilds – Substitute as above and also apply a multiplier boost to any win they’re part of. If more than one is involved, multipliers are stacked.
- Trigger Wilds – Award 10 free spins when part of a winning combo. Multiple Trigger Wilds in separate wins grant additional sets of 10 spins.
Free Spins Mode. Triggering 10 Free Spins via Trigger Wilds launches a more dynamic version of the game:
- The tower expands to 6 rows and 96 symbols, increasing as follows:
- Spin 3, 5, 7, and 9 – One additional row added per milestone
- Max expansion: 10 rows and 160 symbols
- From Spin 2 onward, only the bottom 1–2 rows are cleared, allowing the upper tower to remain mostly intact for compounding wins.
- Up to 10 Wilds may be randomly added at the start of each round.
- Additional Trigger Wild wins retrigger +10 free spins.
Bonus Buy (non-UK only). Players outside the UK can buy 10 free spins for 60x the stake, with an RTP of 96.37%.
Conclusion
Crystal Towers from Big Time Gaming is a fresh, bold experiment that stands out in the sea of standard slots. The rotating tower, cluster-win mechanic, and chain reactions combine to create a dynamic puzzle-slot hybrid that keeps players engaged from start to finish.
I love the way free spins expand the tower with each milestone, increasing the number of symbols and therefore the chance for bigger wins. Add in stacking multipliers, frequent retriggers, and the rare 36,085x max win, and you’ve got a title that rewards patience and persistence. This slot is certainly a game not just for you, but for BTG who are doing something very different here. But I love to see innovation, and I think this slot stands out for a lot of the right reasons. There are improvements that could be made, perhaps with a newer version, but this one is clearly testing the waters and I look forward to seeing what else they can do.
