Diamond Cart is the first in a catalogue of new slots which use a brand new Revolving Reels mechanic. Any wins will be awarded before the reels rotate 90 degrees clockwise, new symbols will then be populated from the top. This will continue until the game eventually loses. It is the latest 2D/3D hybrid game to be released on the Vulcan framework. The base game has a mixture of 2d/3d elements, mainly to give a natural appearance to the carts as they roll on the tracks across the screen. There is also a fully 3d jackpot game that features a mining cart on a rail track. The cart will move down the track and stop at junctions. The player is prompted to choose a direction (left or right) until the cart comes to the end of the line at a room with various gems and treasures.

The Miner Multiplier modifier will increment a multiplier (starting at x2) for every spin until a win is achieved. The more losing random spins occur, the higher the multiplier will become until a win lands. Once a win is achieved the multiplier is applied to every subsequent win in that game cycle.

The Miner Movement modifier will spin in a losing combination on the reels but then the miner can pull his lever to rotate the reels 90 degrees until a winning combination is achieved on the reels. This modifier is a guaranteed win spin.

During the Free Spins feature each reel rotation (winning cascade) will increase the multiplier by 1 increment. Therefore, should a winning combination occur after entering Free Spins, the multiplier will increase from x1 to x2 on rotation and any wins that follow will be multiplied by x2. On that same spin, if there is a further win after the reels rotate, the multiplier will move to x3, and so on. The multiplier will persist and increase through all Free Spins, cascades and retriggers and never resets or decreases until the Free Spins are exhausted. This can lead to huge multipliers and huge win amounts in this volatile feature.

Diamond Cart also has a 3D jackpot game that allows the player to choose their path through the mines in the hope of eventually finding the huge progressives jackpot or one of 3 the smaller fixed pots.
