The Four Inventions - Review, Demo Play, Payout, Free Spins & Bonuses

Introduction

This is an interesting slot with a unique theme you probably haven't seen in many (or any) other slots. The Asian-themed slots game is based around the idea of four iconic inventions. These inventions make up the game's highest-paying symbols. It's certainly an attractively designed game with smooth gameplay and some great graphics. Many gamers will love the fact that there is a Power setting, which makes it possible for you to buy the bonus feature rather than waiting for it to be triggered. More on this later. For other, more traditional Asian-themed slots, check out our relevant section of games.

Theme, Graphics & Soundtrack

The theme of this game is great Asian inventions, which might sound a little niche to say the least! While there are countless Asian themed slots out there, we've never seen one that focuses solely on great inventions. The game is very sleek and stunningly well designed. The graphics are fast and smooth with no lagging or sluggish loading times. The game is accompanied by a charming musical soundtrack and extra sound effects whenever certain things happen - such as when you land a scatter symbol or trigger a win. We wholeheartedly recommend you take a look at some of our other EURASIAN Gaming slot demo titles for more great-quality graphics and animations.

How to Play The Four Inventions

This is a very simple game to play, and it couldn't be easier to get started. Here are some step-by-step instructions, however, just in case you need them.

1. Launch the game and wait for the intro montages to end.
2. Locate the bet per line display.
3. Use the arrows on either side of the bet per line display to cycle through the available bet options. The total bet display to the right will change as you adjust the bet per line.
4. When you're happy with your total bet, hit the spin button.

That's it! There is also an autoplay function, which lets you set up a pre-determined number of spins. If you set this up, you can stop it at any time by clicking the stop button.

Bet Sizes & Paytable Wins

This is a fixed payline slot with 25 lines, so all bets will be a multiple of 25. The smallest bet available is 25 coins. The largest bet available is 200 coins per line, but the exact bet sizes and currency used might well vary across different sites. The max win available from a single payline is 800x your line bet from the fire symbols. However, the maximum single win is from a 200x your total bet bonus, which you can trigger in the free spins bonus round only.

The Four Inventions Bonus Features

The Four Inventions has a rather unusual free spins feature that you're bound to love. You can trigger the free spins by landing three scatters on the reels. You'll be taken to another screen with four different sets of reels, all of which spin one after the other. Each of the four reels represents one of the four invention symbols, and the associated symbol is displayed to the side of the reels. Every time any of the reels lands a win, that set of reels will spin again, giving you more chances to win. Another cool feature is that any time a win formed by one of the invention symbols lands, those symbols get added to the number of spins each set of reels has left. For example, a winning combo of four of the paper symbols would add another four spins to the paper set of reels. In the event that all four sets of reels are winning at the same time, you'll get a bonus prize of 200x your total bet! The free spins feature ends when all wins have finished playing out and all the stored free spins of each set of reels have been used up. It might sound complicated, but you'll soon work out what's going on if you're lucky enough to trigger this feature!

Overall Review - Our Verdict

8/10. There might be a few too many dead spins in the base game, but the fantastic and unique free spins round certainly counts for something. We've never seen a free spins round quite like this. While it could potentially be a dud, there is also the possibility of winning more and more free spins as the winning combos add up, meaning this could go on for quite some time. If you love this slot, it's also worth your time to check out Caishen's Gold slot, which you'll also like.
