General info about the Demi Gods series
Everything in the slots revolves around a common theme: Greek mythology, its gods and heroes. Spinomenal tries and has tried to add something interesting to each new title. So, the entire package of slots is quite impressive in terms of bonus features, e.g. you have free spins, win multipliers, stacked wild respins, expanding wilds, extra wilds, moving reel respins, shifting reels and over a dozen other on-reel bonuses and special features.
To make our research more vivid, let’s take a look at the fourth series, which comprises the following video slots:
This is the smallest collection of episodes in the entire series – you have only three:
- Book of Demi Gods IV Thunderstorm
- Book of Demi Gods IV
- Demi Gods IV
Demi Gods IV short review & our impressions
Well, the first reaction was a surprise when we saw the game had 50 paylines. One would expect a no-payline structure from a 6-reel slot – maybe, Megaways or a classic ways-to-win structure.
The lowest 1-cent bet per line turns into 50 cents per spin, which is inappropriate for some low rollers. On the other hand, the $500 max is a perfect deal for high rollers.
Demi Gods IV has good bonus content. Apart from a classic wild symbol, which acts as a regular substitute, the video slot has three random features that can trigger at any time during normal play.
There are also free spins, which are also very good, because there’s a bonus wheel triggered at the very beginning. It determines the extra bonuses that will accompany your free spin rounds. Let’s look closer at three random bonuses in Demi Gods IV.
Synced reels in Demi Gods IV
The login behind the Synced Reels is well-known to experienced players. Two or more adjoining reels show the same set of symbols, which increases the probabilities for a winning combination. The game can randomly generate a set of 2, 3 or 4 synced reels – certainly, the last option is preferable and potentially most beneficial of all.
Power Spin in Demi Gods IV
This is another random feature that removes low- and medium-valued symbols before a spin, leaving only more profitable icons on the reels. It has three levels, chosen by the game randomly and automatically. As a result, you can have a more impressive cash prize than usual.
Random win multiplier in Demi Gods IV
Sometimes, during a normal game, a random multiplier of x2, x3 or x4 will apply to the existing winning combination. There’s nothing special about the feature.
Free spins in Demi Gods IV
The feature is triggered when a bonus symbol lands on reels 1 and 6 at a time. Before free spins start, a Bonus Wheel activates. It determines which random bonus, described above, will run for the entire duration of the free spins. To boost your FS further, you can buy another spin of the Bonus Wheel and win an extra feature or upgrade the current one. Whatever the case may be, you always get 10 free spins, which can be re-triggered.
Max win in Demi Gods IV
Now comes the most interesting part. The top bet in Demi Gods IV is $500 ($10 per line). Based on the paytable (see below), we can calculate the theoretical payouts you can get per one best-paying combination. So, when 6 Temple symbols appear on a payline, you can win $500 / 50 x 1,000 = $10,000.
Do not forget about bonus multipliers up to x4. Besides, profit-generating combos can land on more than one payline. Therefore, we can conclude Demi Gods IV is a very good video slot in terms of payouts. Its highest RTP is 96.2%, which is also pretty good.
Book of Demi Gods IV – two slots
Both slots look and feel identical. Book of Demi Gods IV and Book of Demi Gods IV Thunderstorm have the same symbols and bonus features. They differ in the background picture (one is fully coloured and another is grey) and a few essential features that are not visible at first sight – you should enter the paytable to find them. The common features in both slots are:
- Scatter Wild symbol: It substitutes for other symbols as a wild and triggers 10 free spins when 3 land in any position. Besides, they pay out x2, x25 and x250 for 3, 4 and 5, accordingly.
- Free spins
- Expanding symbol during FS
- Bonus Buy: It costs x104 bet.
- Maximum win: $50,000 per spin
The differences in the video slots:
| Parameter | Book of Demi Gods IV | Book of Demi Gods IV – Thunderstorm |
|---|---|---|
| RTP | 88.94% – 96.14% | 88.92% – 96.18% |
| Paylines | 10 | 5 |
| Max bet | $100 | $50 |
| Free Spins | All symbols can be expanding during FS | Only high symbols can be expanding during FS |
As you can see above, the two Book of Demi Gods IV slots are similar. If we were to choose which to play, we would rather pick the basic version, not Thunderstorm.
