Lines Santa's Vault by Push Gaming is a Christmas-themed slot with a 3x3 reel layout and low volatility. The game uses five paylines, with bet sizes starting from 0.10. Its RTP range is listed between 85.84% and 96.37%, depending on the version shown.
The feature set centres on Enhancer Reels, where Addition Symbols increase values and Multiplier Symbols raise them further. Instant Prizes can land on reels 1 and 3, offering coin values and jackpot awards such as Mini, Minor, Mega, and Grand. A Vault Collector on reel 2 helps gather these prizes, while coins stacked into the vault can build towards extra rewards.
The bonus game begins with three spins and uses dynamic resets when Instant Prizes land. A Sticky Collector starts on reel 2, with up to three Collectors possible during the round. Players can use the demo version to play for free and practice before playing for real money, while reviewing the paytable and bonus trigger conditions.
