Santa's Puzzle by Endorphina is a five-reel, four-row slot with 50 paylines and high volatility. The game uses Wild symbols that substitute for all symbols except the Bonus symbol, while the listed RTP is 96.06% and bets range from 0.1 to 50.
The main feature is the Puzzle Bonus Game, triggered when four Bonus symbols land on reels 1 and 5. In the bonus round, players work on a 5x4 empty puzzle grid, with three attempts to land each piece. Successful placements reveal parts of a hidden image, reset the remaining attempts to three, and award the multiplier attached to that grid position, which can reach x16.
Santa's Puzzle also includes twelve themed images linked to individual girls and months, with a complete picture unlocking an HoHoHot Prize worth 1,000x the total bet. A Classic Risk Game is available to double winnings up to ten times. This demo version lets players play for free and practice before playing for real money.
