Description

Diamond Mystery - 40 Imperial Crown deluxe is a regal fruit-and-crown slot in the Diamond Mystery series with five reels, four rows and a 40-line setup. Developed by Greentube, the title fits the online casino slot catalogue through a presentation centred on a royal fruit-machine design with crowns, gems, polished fruits and decorative gold trim.

The game uses a 5 reels and 4 rows format with 40 win lines. Its core rhythm is organised around regular symbol combinations, special icons and a feature layer that is introduced through clearly marked symbols rather than through complex menu navigation.

The visual identity focuses on crowns, diamonds, classic fruits, sevens, Wilds and Scatter-style stars. Symbol values are arranged in a direct hierarchy, so the main icons, Wild-style symbols and feature markers can be identified without interrupting the reel view.

In functional terms, the game combines a royal fruit-machine paytable with Diamond Mystery-style gem presentation and special symbols such as Wild and Scatter icons. The overall structure keeps the theme, grid layout and feature triggers separated in a clear and matter-of-fact way.
