Book Of Gods

Right, so Book of Gods from Big Time Gaming takes the well-worn Egyptian mythology theme and gives it the BTG treatment – which means you’re looking at something a bit different from your standard book slot. The setup runs 5 reels with 10 paylines, and while that sounds fairly traditional, this developer rarely does things by the book.

The star attraction here is the free spins feature, triggered by landing three or more book scatter symbols. You’ll get 10 free spins to start, and here’s where it gets interesting: a special expanding symbol is chosen at random before the round begins. When this symbol lands during free spins, it expands to cover the entire reel, potentially filling the screen with matching symbols. The expanding mechanic doesn’t require symbols to be on adjacent reels either, which can lead to some decent wins if you land the right symbol enough times. Re-triggers are possible too, adding another 10 spins when you hit three or more scatters again.

What’s worth noting is the volatility sits somewhere in the medium to high range, so you’ll need a bit of patience between those bonus rounds. The theoretical RTP isn’t publicly available for this one, which is frustrating – always worth checking with your specific casino before committing serious bankroll. Base game action can be a bit quiet, typical for this style of slot where most of the heavy lifting happens during the feature. When those expanding symbols align properly though, particularly if you land a high-paying symbol as your special, the potential is definitely there.

Big Time Gaming’s production values are solid throughout. The graphics lean into that ancient Egyptian aesthetic without going overboard, and the whole thing runs smoothly enough. It’s not reinventing the wheel – book slots are ten-a-penny these days – but the BTG touch means it handles well and the maths model feels fair. If you’re into this genre and fancy something from a respected provider, it’s a decent choice for a session.
