Diamond 7™ by Greentube is a gemstone-themed video slot built on a 5-reel, 3-row layout with 5 fixed paylines. The paytable shows fruit and crystal symbols alongside a prominent 7, with prizes awarded for matching combinations from left to right. The rules panel also notes that scatter symbols pay anywhere on the reels and can be added to line wins.
The game includes a gamble feature after a win, allowing players to choose red or black for a chance to increase the payout. A collect option, autoplay function, and bet controls are visible in the interface, while the stated RTP is 95.66% and the stake range runs from 0.4 to 100. Players can use the demo version to play for free and practice before playing for real money.
Visually, Diamond 7 uses a jewel-toned casino style with crystal motifs, gold framing, and bright symbol artwork. The central 7 symbol is the highest-value icon in the paytable, and the presentation focuses on clear reel visibility and straightforward slot mechanics.
