Diamond Chief Slot Review

Diamond Chief from Ainsworth is a slot game bursting with exotic animals and an inhabited island full of beautiful scenery. But beneath the reels lay a treasure trove just waiting to be discovered. You are invited to take a journey into the unknown and get up close with many creatures that may become extinct. As you spin the reels, you will not only come across animals, but you will also come across wilds, scatters, multipliers and free spins – but not only that, you could win a life-changing 500,000 should you charm the diamonds onto your reels.

Ainsworth (aka Ainsworth Game Technology) have a series of slot games that fit into a high roller category of slots. This means that all of the slot games that make up this genre allow players to stake a maximum of 10,000 a spin in the hope of trigger substantial amounts of cash. Crystal Cash, Gran Bazaar, Cash Cove and Crazy Goose are other titles in this series, but unlike these high roller slot titles, diamond Chief only offers a 500,000 non-progressive jackpot for the same stakes.

Blooming Good Design

This slot machine has been designed to resemble a tropical jungle or island, with its masses of green shrubbery, trees and crystal clear skies. Wood binds the reels together in a strange structure; reels 1 and 2 and three symbols high whilst reels 3, 4 and 5 are four symbols high. This design of the reels can be found with the Crazy Goose slot game too. Symbols that fall upon those reels are; Diamond Chief logo, diamond, waterfall, elephant, gorilla, hippo, tropical bird and card values 9, 10, J, Q, K and A.

Players will have no difficulty in making their bets or understanding how to play the game, thanks to the control panel beneath the reels – this puts you in control at all times. Use the autoplay feature to automatically spin up to 100 spins at a time or press the large red spin button manually if you’d like to play the game yourself. In our opinion, the autoplay feature takes all the fun out of the slot game.

Reel Info

Ainsworth specialise in 5 reel, 100 payline slot machines but you can control the paylines and bet per line to suit your own budget. Minimum stakes are just 0.01 a line, so for all 100 you will be staking 1.00 a time. More lines in play, the more chances you have of triggering a win or the free spins feature.

Maximum stakes are indeed 10,000 like the other high roller slot games offered by the company, but unlike the other slots, all of the symbols on the Diamond Chief reels allow you to win at least your stake back and more.

Take the Flying Horse slot for example, it offers a 10,000 maximum spin but only two symbols offer a higher cash sum than the stake being made. Every symbol within this slot game will offer 10,000 up to a cool 500,000. Five of a kind of the diamonds will return that 500,000 non-progressive jackpot.

Features to expect

Three or more of the diamond symbols offer 10 free spins. During the free spins bonus mode, the symbols on the reels will change to offer much lower cash amounts than those symbols found within the base game. Not only that, but there will also be the inclusion of a tribal shield into the free spins bonus – this will act as another scatter symbol (one that doesn’t offer free spins). Whenever the shield appears, a multiplier value of either 2x or 3x will be applied to the winnings. Two more diamond symbols will award 5 additional free spins.

Diamond Chief logo is the wild symbol and will replace every other symbol (bar diamond) to help create a win on your paylines.

Overall feeling

The big cash certainly comes from the non-progressive jackpot, but triggering that may not actually happen – so to get your hands on big wins you will have to trigger the free spins bonus. The free spins offer large amounts of wins thanks to the combination of wilds and multiplier values of 2x or 3x.

Diamond Chief is a great addition to Ainsworth’s portfolio of games and will suit all types of players – not just high rollers. We found this slot game to be a medium to high variance slot game and features a return to player (RTP) percentage of 94.37%.
