iders Greentube have released their first Novomatic 3D slot, Marilyn’s Diamonds.

The game includes Reel Refill, a new feature that sees sliding symbols replace spinning reels.

Symbols slide into their vertical position, with the winning symbols exploding when revealing a winning combination, leaving the symbols above them to slide down and fill the empty position, thus creating win chains.

The new slot, which is already available on the site of Greentube business partners GameTwist.com, also sees Marilyn’s Diamonds fly across the screen in 3D when a winning combination is shown.

Greentube CEO Thomas Graf said: “We take great pride in being at the forefront of the global remote gaming industry, being innovative and bringing state of the art products and services to our customers and end users.

“During 2013 our partners will see even more great Novomatic and Greentube innovations being made available through our online, mobile and terminal-based systems.”
