100 Lucky Sevens by GameArt is a 5x4 slot game with 100 paylines and 11 symbols. The 7 symbol acts as the Wild, substituting for all symbols except the Scatter star. Wilds appear only on reels 2, 3 and 4, where they expand to cover the full reel and create stacked reel effects.
The star symbol is the Scatter. Three Scatters trigger ten Free Spins, while additional three-Scatter combinations during the bonus round award ten more spins. Scatters do not pay directly, and the Wild symbol does not produce a separate payout. The game is available in a demo version, allowing players to play for free and practice before playing for real money.
With a reported RTP of 96.41% and bet sizes from 0.1 to 100, 100 Lucky Sevens presents a fixed-payline format focused on classic slot mechanics. The review page near the demo launcher gives a brief overview of the main features, including the Wild expansion and the Free Spins bonus game.
