Lines Christmas Factory by Vibra Gaming is a 5x3 slot with 25 paylines and medium-high volatility. The game is built around a festive factory theme, with an RTP range shown in the game data from 75% to 95% depending on version. The maximum win is 4,500x the stake.
Key features include stacked Elf Wilds, which substitute for regular symbols, and the Red Letter Money Respins bonus. That feature starts when six or more red letter symbols land, awarding three respins that reset when new symbols appear. The Candy Bonus free spins round is triggered by three Free Spins symbols on reels 1, 3 and 5, giving eight spins and the chance to add more during the round.
This Christmas Factory demo version is available to play for free, which can help players practice before playing for real money and review the bonus mechanics in a risk-free setting.
