Book Of Demi Gods III Slot Review
A gnarled tree trunk fills the left edge of the screen, its dark foliage fading into blue mist, and a warm-lit ruin glows faintly behind the reels. Book Of Demi Gods III, from Spinomenal, is one of the purest book games you’ll come across: everything outside the bonus round exists to get you into it, and one pick made before a single free spin decides how the round goes. That’s a bolder choice than it looks in a format this crowded. It plays on a 5×3 grid with 10 fixed paylines and an RTP of 96.14%.
Five Reels, Ten Lines and a Very Busy Wild
All symbols pay left to right from the leftmost reel, and only the highest win on each line counts. Wins are multiplied by the bet per line, and multiple line wins in one round add together into the total. With just ten lines, the paytable is short and steep.
The character symbols are a helmed Viking, a red-haired woman, a green elf warrior and a fire demon, with the royals filling the bottom of the table. Values below are multiples of the total bet:
- Viking (helmed warrior): 2 pays 50x, 3 pays 500x, 4 pays 5,000x, 5 pays 25,000x
- Red-haired woman: 2 pays 25x, 3 pays 200x, 4 pays 2,000x, 5 pays 10,000x
- Green elf warrior / Fire demon: 2 pays 25x, 3 pays 150x, 4 pays 500x, 5 pays 3,750x
- A / K: three of a kind pays 25x, climbing to 200x for four and 750x for five
- Q / J / 10: from 25x at three up to 125x at four and 500x at five
The ceiling on the reels is the Viking’s 25,000x for five of a kind, a serious number for a ten-line game and the figure every full-screen expansion is chasing. The drop beneath it is steep by design. Only the top three symbols are worth writing home about.
The wild does double duty here, and it carries more weight than a normal substitute. It counts as any symbol on the lines, and it’s also a scatter: three or more anywhere on the reels pays out and triggers the free spins round.
On ten lines, a scattered wild that pays is a meaningful part of the base game’s income:
- 3 scattered wilds pay 2x the bet and trigger 10 free spins
- 4 scattered wilds pay 25x the bet and trigger 10 free spins
- 5 scattered wilds pay 250x the bet and trigger 10 free spins
Scatter prizes are paid in addition to any regular line wins from the same spin, so a triggering spin can pay twice. Everything around the reels is familiar: auto play with a configurable spin count that can be paused at any point, a turbo mode for shorter rounds, and bet controls that lock during free spins.
Free Spins: The Wheel and the Expanding Symbol
The Free Spins Wheel
Three or more scattered wilds award 10 free spins at the same bet per line as the round that triggered them. Before the spins begin, a wheel appears loaded with every symbol in the game except the scatter wild itself. Spin it, and whichever symbol it stops on becomes the expanding symbol for the whole round.
It’s a small piece of theatre that does real work. Landing the Viking as your expanding symbol and landing the 10 are very different rounds, and the wheel decides which one you get before a single free spin plays out. The buy feature sends you through the same wheel, so there’s no way past it.
The Expanding Symbol
After each free spin’s result is determined, the chosen symbol expands to cover its reels and form new paylines on top of the existing ones. Two rules govern it. The expansion only happens if it produces a win, and the expanding symbol pays in all active lines, whether or not the winning symbols sit on consecutive reels.
That second rule is the generous one, and it’s the reason the round can fill a screen. Expanded symbols count separately from the original result, so a full grid of the top symbol pays the line wins and the expansion both. It’s the most open-handed reading of the mechanic you’ll find in the format.
Retriggers
Free spins can retrigger, and a retrigger awards 10 additional free spins. The expanding symbol stays as the wheel chose it, so a retrigger extends the round you already have rather than rolling the dice again. Landing more scattered wilds mid-round is the only way to lengthen it.
Buy Feature
There’s a buy option for players who’d rather skip the wait. The Buy Feature purchases an immediate free spins round: clicking the button opens a window where you set the bet you’ll play the round at, and the buy price adjusts to match. Confirm, pay, and the wheel spins straight away.
Because the price scales with your chosen bet, the purchase is proportionate at every stake level. The wheel still decides your expanding symbol after the buy, so paying your way in doesn’t protect you from a low-value pick. What you’re buying is the round itself, not the outcome of it.
Our Honest Verdict
Overall Rating: 7.2/10
This is a game you wait in and then hope in. The mist and the ruins don’t do anything while you’re waiting, and neither do the reels most of the time; the reason to sit through ten lean lines is one spin of a wheel that decides your whole bonus round before it starts. When that pick lands well, the round underneath it delivers more than most book games manage.
The strength is the expanding symbol’s rulebook. Paying across all ten lines regardless of where the symbols sit, on top of the original result, is as generous as this mechanic gets anywhere, and it’s what makes a Viking-covered grid worth chasing. The weakness is that there is genuinely nothing else. Buy the round or wait for it, either way you’re playing the same single feature, and the wheel can still hand you the 10.
It suits book-format players who want the classic loop without decoration, and the mist makes the waiting prettier than most. Anyone after layered features or steady small wins won’t find them under the trees. The gods here hand out one gift, and it’s the right one.
