Sanctuary (Big Time Gaming) – Review & Demo Play

Sanctuary Slot Overview

Sanctuary is a Big Time Gaming video slot set against pyramids and a red sky, soundtracked by The Cult’s She Sells Sanctuary. It plays on 6 reels, 4 rows and 4,096 ways to win. Stakes run from 10p to £20 a spin, with a default RTP of 96.38% and a very high volatility profile. The base game leans on full reel wilds, while free spins can lift you into up to four simultaneous gaming grids, backed by Win Exchange and an optional Bonus Buy.

Sanctuary Slot Information

Behind the transparent six-reel window in Sanctuary sits a towering pyramid capped in gold, with a red to yellow sky pulsing to a laid-back riff. A frame marks the four middle reels, separating them from the first and last; Wild Symbols land only within that frame on reels two to five. Wins form from left to right on adjacent reels, needing three or more symbols, bar the top skull pharaoh. The slot runs smoothly on mobiles, tablets and desktop.

Sanctuary Slot Features

Two Full Reel Wild Symbols drive the base game in Sanctuary. Gold and Purple expand to cover all four rows on any of reels two to five, substituting for regular pays and counting as a single symbol. Any win involving a Purple Wild is multiplied by x8, which can swing a spin in style. These full reel wilds are switched off during free spins, keeping their fireworks for the base while the bonus round pivots to sticky setups.

Land three to six scatters to trigger seven free spins played on one to four gaming grids. Before starting, you may gamble on a segmented wheel to upgrade the number of grids; miss and you take the black number shown, with zero ending the feature. During the round, an Ankh can land on reels two to five to place a sticky wild in that position on all grids. Fill a reel with four sticky wilds to create a full reel x4 wild and add three spins, up to twelve extra.

Sanctuary also carries BTG’s Win Exchange and a Bonus Buy. Hit a win of 80x bet or more, and you may exchange 80x for seven free spins. Pocket between 25x and 80x, and you can risk the entire amount on a wheel for a shot at those seven spins. If you prefer skipping the base grind, you can buy the feature for 80x. Availability varies by jurisdiction, so check what your version offers.

Sanctuary Slot RTP & Volatility

RTP and volatility in Sanctuary strike a familiar BTG balance. The default return to player sits at 96.38% on standard spins, nudging to 96.39% when you access free spins via Bonus Buy. The maths model is very high volatility, mixing dry spells with sharp bursts when features line up. Headline potential reaches 44,070x the bet in free spins, with up to 20,480x possible in the base game. The game uses a 6x4 layout with 4,096 ways, allowing hits to form across adjacent reels.

Sanctuary Slot Paytable & Symbols

Sanctuary uses ten regular-paying symbols. The lower set is 9, 10, J, Q, K and A, paying around 0.5x to 1.2x the bet for a six-of-a-kind. The higher-paying group features the Eye, a scarab, an Anubis-like figure and a skull pharaoh. Land six of these for 1.5x to 15x the stake, with the skull pharaoh also paying from a two-of-a-kind. Payouts apply left to right on adjacent reels from the first reel, in line with the 4,096 ways engine.

Specials tie the theme together. Gold and Purple Full Reel Wilds appear on reels two to five in the base game, covering an entire reel and substituting for regular pays; any win with a Purple Wild is multiplied by x8. The Pyramid acts as the Scatter to trigger free spins. In free spins, the Ankh cross lands on reels two to five to place a sticky wild that duplicates to the same position on all grids, with four on a reel upgrading to an x4 wild and adding three spins.

Sanctuary: Slot Verdict

For me, Sanctuary hits that rockin’ good game vibe without shouting. It doesn’t wave monster multipliers around, yet it quietly goes about knocking together thrilling action. The Purple full reel wild can flip the base in a heartbeat, while sticky wilds across multiple grids give the bonus a proper lift. I’ve seen the base throw big spikes, and the feature push hard when reels stack up. It feels like a hard-working performer with a deep groove.

I’d add a note of caution on the gamble wheel. Upgrading grids can pay, but the ride can be brutal if the pointer lands badly, so I tend to ladder up only when the odds look fair. With 44,070x on the table and 96.38% RTP, there’s plenty of headroom for sessions that sing, backed by that classic track. If you want a straight route, Win Exchange and the Bonus Buy give clean entry to seven spins.
