Diamond 7 (Greentube) – Review & Demo Play

How to Play Diamond 7

Diamond 7 runs on a five by three setup with fixed lines. You bet on all five each spin, so I set stakes with the Bet per Line control and leave the Lines tab alone. The range mirrors the Novomatic spec at 8 to 200 coins per line, giving a total of 40 to 1,000 coins per spin. Spins are quick, the interface is clean, and the pace suits a classic fruit-themed slot with punchy base game hits.

I use Autoplay for brisk sessions, up to 100 spins, then jump into the Paytable to check values at my stake. Desktop, tablet, and mobile all feel smooth, and the reel rhythm stays consistent across devices. The glittering Diamond 7 sits at the top of the ladder and can land big returns on a single spin, so I chase clear line-ups rather than fancy mechanics. It is straightforward, and that is the appeal.

Diamond 7 Symbols & Payout

Symbols stick to fruit machine roots. Cherries, lemons, oranges, and plums handle the lower tier, while grapes and melons sit above them. The star acts as a scatter and pays from any position, cutting through line rules when three or more land. The headliner is the Diamond 7. Line up five and you are looking at the million-coin ceiling, with smaller sets paying down the scale. It is all about clean sets of identical icons.

Payouts scale with stake size, so I always check the in-game paytable before I push limits. Star scatter wins top out at 50,000 coins in the table I saw, which helps pad sessions when lines go quiet. Low symbols keep things ticking, the premium fruits lift the averages, and the Diamond 7 drives the headline outcomes. As ever with fixed lines, clarity matters, so I track which reels favour the stronger sets.

Diamond 7 Free Spins and Bonus Features

There are no wilds, no free spins, and no side bonus rounds in Diamond 7. I like that the feature set stays lean. Star scatters pay anywhere to break up dry patches, then the gamble feature kicks in after wins. Pick the card colour for a shot at doubling, with a chance to go higher on some versions, which adds bite without slowing the flow. The focus stays on fast base game action and line-driven payouts.

Diamond 7 RTP, Maximum Win & Volatility

RTP sits at 95.66 percent on the Novomatic sheet, with medium volatility that blends steady hits and punchy spikes. The maximum win reaches up to 1,000,000 coins through high-value Diamond 7 combinations, so the ceiling is there if the grid aligns. High stakes players can lean into the 1,000 coins per spin top end, but I find the lower brackets give a tidy rhythm while still letting the star scatter and 7s do their work.

Diamond 7 Verdict

Diamond 7 takes the fruit slot template and polishes it with a gemstone look and fast spins. Five fixed lines keep decisions simple, which I enjoy when I want pace. The base game does the heavy lifting, and that suits me fine on mobile and desktop alike. I rate the star scatter because it pays from any spot, and the Diamond 7 symbol carries real weight when lines connect. That mix keeps sessions lively without a wall of features.

I lean on the gamble feature after small to mid wins, as the card guess adds a neat layer without dragging the session. It is easy to tap in and out, so I keep control of the risk. The visuals have a crisp, blue gloss that fits the theme, yet the math profile is the real draw here. You get traditional play with proper top-end potential rather than a maze of mechanics.

If you want a traditional fruit machine with straight rules, Diamond 7 does the job. Start in free play to feel the spin speed and line cadence, then scale stakes when the flow suits your bankroll. I keep it tight, chase clean five-of-a-kind lines, and let the scatter and 7s set the tone. For me, this slot hits that sweet spot between quick sessions and a headline prize worth chasing.
