Diamond Charge Extra is a simple but fast paced slot machine from Iron Dog Studio. With only five paylines, the regular wins will be few. The payouts will come from the Collect Feature and the Hold & Win Feature, both of which can deliver fixed jackpot wins. The symbols are playing card icons and gemstones. The bright colours and simple designs are perfect for playing this video slot on the smaller screens of smartphones. The usual facilities like Auto Play and Quick Spin are included, so you can customize your gameplay.

The huge disadvantage of Diamond Charge Extra is its extremely low Return To Player of 93.33%. This is not a suitable slot game for real money play. Read the review and if you enjoy the features go ahead with the demo version using the play money provided.

The bet range of $0.10 to $50 is more suited for low roller players. 

How to read the paylines?

Diamond Charge Extra slot game has five paylines running across a grid of 5 reels and 3 rows. You will need three or more like symbols appearing on successive reels starting from the first one to be awarded payouts. The paylines are displayed in the image below.

How to read the paytable?

The paytable shows the amounts payable for the different win combinations. Not all symbols pay the same. The highest payouts are awarded by the wild symbol. You will note that as you change the bet, the payouts in the table will change. The paytable in the image below is for the largest bet of $50.

The table below displays the payout multipliers for each symbol. The table will allow you to work out the payouts for all bets without toggling the game rules. It will also help you to compare the payout table of Diamond Charge Extra with that of other slot games.

Diamond Charge Extra does not have the usual free games feature, but there are two other bonuses that more than make up for it. 

Bonus Features

  • Wild Symbol Yes
  • Scatter Symbol No
  • Payout Multipliers No
  • Bonus Game Yes
  • Free Games No
  • Gamble Game No
  • Bonus Buy No
  • Fixed Jackpot Yes
  • Progressive Jackpot No
  • Auto Play Yes

Collect Feature

The Golden Diamond (with extra charge) is a Special Collector symbol that appears only on reel 3. Then there are Cash symbols in the form of gold coins that can appear on the other four reels. The Bonus Cash symbols have multiplier values from 1x to 10x the stake. The Jackpot Cash symbols award one of the fixed jackpots. The Mini pays 20x the stake; the Minor pays 50x the stake; the Major pays 150x the stake; and the Mega pays 1000x the stake. 

The Cash symbols do not contribute unless there is at least one Special Collector symbol on the grid in the same spin. When this trigger occurs, the total value of the Cash symbols, based on the selected stake, are added and credited to the player’s account.

diamond-charge-extra-slot-collect-feature-img

Hold & Win Feature

The Hold & Win feature is triggered when a Special Collector symbol and at least four Cash symbols appear on the reels in the same spin. You start with three respins. The paylines are disabled as are the regular symbols. You will have only Special Collector symbols, Cash symbols, and Blank symbols (in the form of a diamond silhouette)

The Special Collector symbols are sticky and remain on the reels. On each respin they collect all the multiplier and jackpot values from the Cash symbols. If a Cash symbol lands on the grid, the number of respins are reset to three. If you get three respins without any Cash symbols the Hold & Win feature ends.  

diamond-charge-extra-slot-hold-and-win-feature-img

Ante Bet

The Ante Bet increases the staked amount to 1.5x the selected bet. The payouts are based on the selected bet, but the reels are different and the chance of triggering the Hold & Win feature is doubled. There is no change in the Return to Player.

This section analyses the risks and returns associated with Diamond Charge Extra. You should understand these before deciding whether to play this slot game. 

Maximum Wins

The maximum win in any spin is 5,000x the bet. This limit is on par with most slot games. Once you reach this limit the spin will end, even if you have respins left in the Hold & Win feature. 

diamond-charge-extra-slot-mega-win-img

Volatility

With only five paylines, the slot game would be expected to have high volatility. However, our experts have determined the volatility to be in the higher end of the medium range.  

Return to Player (RTP)

We do not recommend any slot for real money play that has an RTP of less than 94%. There are many video slots with high RTP listed at Jackpot Slots Canada and you may try those.

Diamond Charge Extra is ideal for mobile gaming. The sharp and simple symbols stand out against the plain blue background to the reels. The diamond sitting above the reels keeps collecting the Cash symbols, converting them to diamond chips which keep piling up till the Hold & Win feature is triggered. 

The trigger is announced through a background of multi-coloured gemstones that create the impression of looking into a trunk full of jewels. During the Hold & Win feature the background turns to a dark ruby red. The slot game music is upbeat as well.

Editor’s Verdict: Diamond Charge Extra is not a game that you should play with your own funds. The RTP of 93.33% is way below par. It is true that you may occasionally win, but it is a losing proposition in the long run. You will find all these features in slot games with returns over 96%, so there is no need to risk your money here.

There is no harm in playing this slot in the demo version, especially on smartphones and tablets. The visuals are engaging. Because of the medium volatility, the Hold & Win feature triggers fairly often. You can always activate the Ante Bet since you are not playing with real money.

Diamonds are a recurring motif in online slots. You will find them in retro slots and in mining slots. So much so, that a diamond is a slot player’s best friend. Here are some of the top-tier diamond slots.

Play_responsibly

At Jackpotslotscanada, we understand how fun casino games can be. However, we also want to ensure you always stay safe. If you ever feel like your online gaming is negatively affecting your personal and financial life, you should start using responsive gambling tools and try to protect your players with personal limits on deposits, wagers, and losses.

For more extreme cases, a self-exclusion can help you steer clear of real money casinos from six months to several years. Even when enjoying the best online slot machines for real money, it’s important to play responsibly. Some of the best resources for responsible gambling in Canada include Centre for Addiction and Mental Health, Gambling Therapy, or GamTalk. Learn more about responsible gambling.
