Discover the river's treasures

My impression of the game is that it can take you on a unique adventure like no other game. The gameplay mechanic and the rate at which it makes the spins is relaxingly paced.

This is in stark contrast from most online slots today that are made to go from zero to sixty in a matter of seconds.

Our Spirit of the River slot review outlines gameplay features, payouts, bonus features and my recommendation whether the game may be worth playing or not. If you think this is the game to play today, you can claim a new casino bonus and enjoy the stuff.

Play Spirit of the River Online

SG Digital has equipped the game at hand with a layout of four vertical and six horizontal rows. Winning outcomes are counted for symbols that land on adjacent reels, from left to right and from top to bottom.

The game comes with a special symbol represented by an orb. This symbol adds one animal token to the meter on the right, which can have an effect on the winning outcomes if all four are filled within the current set of 20 spins.

Part of the Spirit of the River slot are runs of 20 spins during which the animal tokens can fill up the meter and trigger the main bonus feature.

Slots Selection's experts haven't seen a game with this particular mechanic, which makes it unique and sought after. SG Digital had released it as a land casino slot so finding this game at an online casino presents an opportunity to play Spirit of the River.

About Spirit of the River Slot

If there are any takers, you can begin playing by pressing the Spin button which can be found on the rocks that are closer to the bottom. The middle area on the same rock face contains the Autoplay button and the topmost rock has the coin stack symbol.

To change the default bet press the latter button. Spirit of the River has a range that goes between 20p and £50.00 per spin. If you change your bet to a lower amount while you've collected two or three tokens, there is a chance that you may lose one or two.

My advice is to play Spirit of the River slot with the same bet until you've completed the 20 spin cycle. If you want to view the paytable and get information for the symbols' values, you need to press the cog button followed by question mark.

Graphics, Design and Symbols

The game brings us to a pristine lake that is formed by a large and not so pristine waterfall in the background. In the front are the reel set, the settings on the right and the priestess on the left.

The latter part of the gameplay is constantly in motion as the woman wearing a large feathered headpiece is controlling a levitating orb with her hands.

These details make Spirit of the River appealing and entertaining. In the center of the action is that which unfolds on the reel set whose symbols portray elements of a Mesoamerican culture.

It was good for a chance to look at symbols that aren't royal cards. The small-paying symbols category consists of pictograms and the high-paying category consists of three royal figures from the royal Aztec court.

At any rate, all of the symbols, the graphic design and the visual effects are glued together for what appears to be a complete online slot.

Spirit of the River Slot Payouts, Volatility and RTP

In terms of payouts, the game has a very wide range of values. Our expectations were met in that regard. In view of the six-row stack of a reel set and eight rows in the bonus feature,  the payouts for the small symbols are like peanuts for your wager.

You can only get 0.05x your bet for landing three brown pictograms of the same kind. The middle tier of symbols represented by three pictograms is slightly better, but you'll need six of the same kind to win 0.5x your bet, which is half of what you would have wagered.

Nevertheless, the game does have the ability to lay down multiple matching symbols from time to time. The small payout values for individual symbol kinds can be offset during the free spins bonus and this is where we can direct our hopes to land a big win.

Over to the high-paying category, you can win between 0.25x your bet for three and 10x your bet for eight warrior symbols. The priestess' symbol pays double for every combination.

Spirit of the River Slot Features

Free Spins Bonus

I announced at the top how the the main feature can trigger. To summarize, once you get a scatter symbol the game begins a 20 spins cycle during which you need to collect all four tokens which are considered bonus symbols.

Spirit of the River awards you 8 spins but if you collect additional four tokens during the bonus, the game will add five extra spins to the list.

Another notable detail is the free spins bonus does come with a wild symbol while the base game doesn't.

Reel Modifiers

Each free spin will include one of the four added modifiers in play.


Random rows on the reel set will expand to eight grid squares. One caveat is that the expanded rows can't host a scatter symbol.


This modifier will scatter several mystery symbols on the reel set which then convert into a symbol of the same kind.


This added feature brings about several wild symbols to random locations on the reel set.


Probably the most coveted modifier, the octopus can add a random multiplier value between 2x, 3x, 4x, 5x or 10x.

Play Spirit of the Wild Slot on Mobile

This game looks a tad odd on a mobile screen, any mobile screen unless you are playing on tablet. This is because the expanding reel set does appear constrained within the confines of your mobile. Nevertheless, you can follow how the action develops and enjoy the game.

David Lame: Bad Magician Slot

This is an odd title, isn't it? We've all probably heard of one particular guy whose name sounds like Dave Lame but let's not mention it. At any rate, you can sense the premise here. The details are: medium to high volatility, 96.10% RTP and a maximum win potential of 4,048x your bet. On this game you can benefit from a two-way-pay system and a number of interesting features.

Our Final Verdict

This game isn't for everyone. You can go through a long stretch of spins and not be met by a single winning outcome that's worthy any particular money. On the other hand, the free spins bonus comes with added inventory that can make the game blossom in its true spirit. Do I recommend it? Yes, but do pace your bets.
