Purple light, gold trim, and three glowing lamps give this release a clear Arabian fantasy frame from the start. Greentube uses 3 Mystic Lamps to build a feature driven slot around gem scatters that can add multipliers, a second screen, or extra lives in the bonus round. That puts it close to newer slot games where the bonus setup shapes most of the session.
Rich violet tones cover the screen, while gold frames and jewel colours keep the setting close to classic magic lamp fiction. The higher symbols use character portraits, a treasure chest, a flying carpet, and a coin pouch, so the theme stays tied to palace treasure rather than desert travel. Lamps and gems carry the main feature identity, and the art keeps them easy to spot against the darker reel area. In an online casino lobby, that presentation reads clearly and quickly, with enough detail to hold the theme without crowding the grid.

Three Green, Gold, and Pink Gem scatters in any mix open the free spins round and place 3 spins on the counter. The trigger gems turn into Coin scatters, five more Coins are added straight away, and each new Coin resets the count while all landed values and jackpot symbols stay locked until the feature ends.
A Green Gem in the trigger adds a random multiplier above each reel for the feature. When three Coins fill one reel, the values on that reel are multiplied by the number above it, with possible values from x1 to x20.
A Gold Gem adds a second game screen and runs two feature boards at the same time. Both boards copy the trigger Coins, then continue on their own, so the full result only pays once both screens finish.
A Pink Gem changes the starting count from 3 to 4 free spins. New Coins in that version reset the total back to 4, which gives the feature more room to hold its values and jackpots on screen.
Mixed gem triggers stack their rules instead of choosing one path over another. That means Green and Gold can place reel multipliers on both screens, while Pink and Gold keep each screen on a 4 spin reset.
The reel set stays fixed all the way through play, yet the way wins model gives the screen more flexibility than a line based layout. Symbols need to connect from the first reel across consecutive positions, so regular wins stay simple to read even when scatters land at the same time. Wilds only enter on reels 2 and 4, which shifts more help into the middle of the grid than the outer edge. In an online casino setting, that makes the base game feel steady, while most of the real variation comes from the gem trigger and coin collection rules.
Greentube keeps this one focused on one main idea and then changes that idea in a few clear ways. We like the fact that each gem alters the same bonus round instead of sending play into several unrelated features, as that keeps the rules easy to follow. The double screen option adds the most visual change, while the multiplier version gives the feature a stronger payout swing without making the base game harder to read. This suits readers who want a compact structure, visible symbol functions, and a bonus round that can develop in more than one direction.
