Tiki Thunder Review

Are you ready to unearth these ancient secrets? Wilds amplify every spin, cascading wins can boost your multipliers, and even the island itself can explode with bonus potential. Don't forget that there are also fast ways to get straight to the best bits if you're prepared to put your hand in your pocket.

Gameplay & Features

Loading Tiki Thunder up reveals a cluster pays mechanic, and you’re dealing with a fairly standard grid. You have low and high paying symbols, picking you up a win across these grid positions, and above the game area, you'll see the multipliers. 

Regular payouts are worth up to 12.50x if you can get a group of 12 or more purple masks.

Each time a win takes place, additional symbols join where the winning symbols were removed. This continues as long as new wins appear. You must have five or more matching symbols that touch vertically or horizontally to grab a win. 

When all the winning symbols disappear, and the new ones join the game, a wild symbol is automatically applied to one of the empty spaces. Each avalanche that takes place will also double the win multiplier, and this resets at the start of each game round. If you reach the lava multiplier, you'll go straight to the next level without needing a win. 

Golden masks can add up to three wilds to the grid. A thunder surge can make the win multiplier increase by a random number of places. There are also giant symbols that can improve your chances of landing a win. 

Bonus Game 

Three, four or five bonus symbols will get you up to 12 free spins, and the win multiplier doesn't reset. With each winning sequence, this progressive multiplier continues to grow, and by your last few spins, you may have something quite substantial to play with. 

You can increase your base bet by 50% and increase your chances of triggering the free spins bonus at the same time. You can also go straight to the free spins feature by paying 100x. There are other direct payments that will trigger different features.

Thunder Surge

The multiplier at the top of the game area continues to grow with each winning sequence. However, you can make this process a lot quicker but triggering a thunder surge. It can activate at the start of any game round and increase the random multiplier by several steps to help boost your next win.

Free Spins

You need at least three bonus symbols to get the free spins feature up and running. 12 free spins is the maximum available, and you'll see the win multiplier start at x1. It continues to grow as it did in the base game, but it won't reset when you hit a losing spin. During the bonus, a gold mask can activate to retrigger the bonus round.

Win Potential

As soon as you see that there's 40,000x up for grabs, you might be hoping for an instant max win opportunity. It can come via a feature or a jackpot, but it isn't present in Tiki Thunder. You're going to need to increase that multiplier figure a number of times to see something decent turn up, and do it the hard way! I'm not sure how long it would take to actually get to 40,000x, but a big run of wins during the bonus game could get you close.

Design

Wooden carvings, flames, palm trees and some tribal drums are pretty standard offerings for a game with this theme. A nondescript Pacific island is presumably where this slot calls home, and you can pick it up and play on a range of devices. Mobile phones are quite happy reproducing this subtle grid slot on the smaller screen.

Our Verdict

Tiki Thunder could be looking to steal the limelight from other 40,000x max win games. It intends to do so via that doubling multiplier, and it gets a little help from some giant symbols and wilds at the same time. These are some powerful features that also appear in other creations, but they could work well together to bring something special to your balance.
