Finding Diamonds in the Gameplay

Triple Diamond Slots look very retro in appearance in comparison to newer slots. It is the definition of a classic slot.

It features three brightly coloured, almost cartoon-like Diamonds in the middle of the slot. These symbols are surrounded by bright purple borders around the reels and buttons.

The most common Symbols are the typical black rectangles with “BAR” written in the centre of them, ranging from 1 to 3 on the same symbol. The symbol that stands out the most is the Triple Diamond Logo symbol.

It features a circle with the words “Triple Diamond” written around the inside, along with the same 3 diamonds shown at the top of the slots main screen.
