100 Paylines (left to right)
GameArt took the old bar-top fruit machine and blew it up to a glowing five-reel, four-row cabinet. 100 Lucky Sevens runs on 100 fixed paylines that pay left to right, and the whole thing is wrapped in neon: red 7s, gold bells, and a candy spread of cherries, plums, grapes and watermelon slices. The RTP sits at 96.41%, which is fair for this kind of release, and the volatility lands in the medium band. So your bankroll won't get wiped in ten spins, but you're not chasing life-changing money on every press either.
The Wild is where it gets interesting. It only shows up on reels 2, 3 and 4, never the outer two, and it does one thing well. When it can finish a win, it stretches to cover the entire reel it landed on. That's an Expanding Wild, and a single one in the middle can light up several lines at once if the right fruit feeds in from the sides. It stands in for everything except the gold-star Scatter.
Those stars are the real prize. Three or more of them hand you 10 free spins, and the expanding Wilds keep doing their thing all the way through. Catch another three scatters mid-feature and you bolt on 10 more spins, with no stated ceiling on how often that re-trigger fires. Don't fancy grinding the base game? A gold Buy Bonus coin sits to the left and drops you straight into the round, though the RTP shifts to 96.64% if you go that way.
Every win can also be gambled. Guess red or black on a card to double it, or call the exact suit to quadruple, up to five times in a row before it locks. You can switch the whole thing off in settings if risk isn't your thing. One small gripe: the base game has no multiplier or upgrade to lean on, so most of the excitement is parked inside the free spins. Outside of that, it's clean, bright, and built for quick sessions.
