About Greentube

Greentube GmbH describes itself as the leading full-service provider in the online and mobile gaming sector. Slots are the core of its catalogue, alongside table games, video poker and video bingo, and the company also sells platform products to operators. Its office list runs from Bratislava and Belgrade to Birkirkara in Malta, Waalwijk in the Netherlands, Vancouver and Athens.

For players, Greentube means a handful of classic games that have been reworked many times. Its site gives Win Ways its own section, next to the Diamond Link and Diamond Mystery series.

Series and Sequels

Book of Ra. The original has nine lines, and three or more Books trigger 10 Free Games with a special expanding symbol. Book of Ra Deluxe moves to ten lines with a paytable that matches the original symbol for symbol. Later editions change one thing each. Magic can build up to nine special symbols, and Temple of Gold lets the number of Books that trigger the bonus set how many special symbols you get.
Sizzling Hot. A five-line fruit slot where five 7s on a line pay 5,000x the line bet. Quattro runs four of them at once.
Lucky Lady’s Charm. A ten-line game in which the Lucky Lady doubles any line win she helps to form.

How the Games Play

Greentube’s edition names are a code, and once you know it you can read any title in the range.

6. A sixth reel that you switch on with an Extra Bet, which doubles the stake. In Book of Ra Deluxe 6, six Explorers on a line pay 15,000x the line bet, three times what five pay.
10. Two reel sets play on every spin, a 4×5 set with 25 lines and a second set beside it, for 100 lines in total.
Win Ways. Lines are replaced by ways, up to 117,649 on six reels, and wins trigger reactions.
Cash Connection. Six special symbols in the main game start Lock and Spin, a respin feature with a collection of prizes.
Twin Spinner. Two copies of the game spin side by side on one screen.

Many of these games keep the gamble feature of the originals, where a win can be risked on a 50:50 call.

Volatility and RTP

Greentube’s classics return less than most modern slots. Book of Ra and Book of Ra Deluxe are both listed at 94.26%, Sizzling Hot Deluxe at 95.66% and Lucky Lady’s Charm Deluxe at 95.13%. Most of the later editions sit at about 95%, and Lucky Lady’s Charm Deluxe 10 is the highest we list at 96.02%.

Greentube rules pages express prizes as multiples of the line bet, and most don’t state a volatility rating or a single maximum win. Those fields are blank on many of our Greentube pages for that reason.
