Colossal Diamonds Slot 

Opting for a more simplistic design in terms of its gameplay, the Colossal Diamonds slot from AGS takes heavy inspiration from early fruit machines. Using a style of playgrid often associated with classic slot games, as well as many retro symbols across the reels, this April 2024 release still incorporates a couple of modern elements. From mixed pay mechanics, all the way to wilds that feature multipliers, the Colossal Diamonds slot is an authentic-looking release that deviates slightly via its bonuses.

A defining aspect of the Colossal Diamonds slot is its playtable, which has 3 reels. Although this might sound fairly common, it is the fact that these reels produce only 1 row of symbols per spin that makes the layout so unique and captures the essence of old-school casino games. As you may expect, considering the setup at hand, there is just a single payline stretching across the polished white reels, a far cry from the counts seen in many contemporary online UK slots today. 

Similar to those found housing classical paintings within museums, the playtable has a frame made from marble and red wood that is decorated with some ornate golden patterns. Sitting directly above all of this is the Colossal Diamonds slot logo that has a giant jewel in the middle of it, fitting when factoring in the name of this release. The rest of the backdrop displays a polished red wall that matches the inner border of the reels, something which contrasts with the blue game buttons along the bottom of the screen. Even with online slots like Gerard’s Gambit and Lucky Rabbit Fortunes featuring the same style of playgrid, the simplified visuals in the Colossal Diamonds slot make this release completely different.

There are four main categories of base game symbols in the Colossal Diamonds slot. These include the cherries, the BARs, the 7s, and the game logo, all of which are their own unique colour and appear in different sizes, matching the retro theme that AGS have chosen.

Lower Value Symbols:

Red Cherries

Single BAR

Triple BAR

Medium Value Symbols:

A number of coloured diamonds have also been added to the Colossal Diamonds slot; however, these have all been selected to act as wilds if they appear across the playgrid. There are no other scatters or bonus symbols, with AGS instead trying to keep the blueprint for this title as straightforward as possible. 

Before getting into the extra bonuses in the Colossal Diamonds slot, it is worth making note of the manner in which the single payline operates in this title. Once the reels stop spinning, each reel is not guaranteed to have a symbol align with the horizontal payline, as they could either appear above or below this designated path. Combinations can only be formed if all 3 reels have a matching symbol across the sole payline.

However, through the inclusion of a ‘mixed pays’ system, it is not only matching symbols that might be able to form combinations. If a mixture of BAR or 7 symbols are landed simultaneously, there is the chance for a combination to be determined, even if these do not match in size or colour, just like in Triple Treasure.

The coloured diamond wilds can only land on the 3rd playgrid reel, and if they do so, they can step in for any other base game symbols across the single payline. However, what makes this Colossal Diamonds slot different from most other retro releases is that its wilds feature multiplier values. Depending on their colour, these can front 2x, 3x, 4x, 5x, or 10x values that may be applied to any combinations they are involved in.

Despite taking a lot of inspiration from some of the first fruit machines, the levels of accessibility when it comes to this Colossal Diamonds slot are very much modern. Through the inclusion of HTML5 technology in this release, and a majority of other UK casino games from the studio over at AGS, the quality is able to remain the same. This software automatically adapts the game to different screens without there being any downgrades, keeping the experience the same on tablets, computers, and smartphones. 

All in all, the Colossal Diamonds slot manages to deliver a modernised gameplay formula, even with its old-school layout, thanks to the modified wilds it includes. The visuals do not stray too far from the classical blueprint established by the genre it joins, making it a fitting addition to this popular sub-category of games.

If the 3x1 playtable and its single payline are something you like in the Colossal Diamonds slot, there are many other releases with the same setup, including Free Reelin Joker and Joker Fruit Frenzy.
