Lines Grand Patron by BGAMING is a 5x3 slot with high volatility and 20 paylines. The game is designed around the Prison symbol feature, where special symbols on the extra reels can lock matching paytable symbols on the main grid for a respin. If Prison symbols appear on both extra reels, the main reels are filled with one random paytable symbol, creating the possibility of a larger line win.
The slot also includes a matching-symbol mechanic that can drop three copies of the same symbol onto the main grid when the same icon lands on both extra reels. Wild symbols are included in this feature, and multiplier symbols can raise the value of winning combinations for a spin. When two multipliers match, their values are added together and applied to wins for that round.
A demo version is available to play for free, which allows players to practice before playing for real money. Bet sizes range from 0.2 to 25, and the listed RTP is 96.67%.
