Naughty Nick's Book

Naughty Nick's Book from Play’n GO takes the book-slot format to the North Pole, with Santa's house in the background and Santa, reindeer, elves and stocking stuffers on the reels. It is a 5-reel, 3-row slot with 10 paylines, medium volatility and a 96.28% RTP, with stakes from €0.10 to €100.

Nick's book is both wild and scatter. It completes line wins, pays anywhere up to 500x the total bet, and three or more trigger 8 free games. Before the round starts, a special expanding symbol is chosen, and it spreads across its reel whenever that creates a win. More books during the feature retrigger it. After any win, a gamble lets you double the prize on a colour guess or quadruple it on a suit. The top win is €750,000, so it fits players who enjoy the classic book mechanic in a festive setting.

The book is the top symbol, and Santa, the reindeer, the stocking stuffers and the elves make up the premium set; some symbols pay from just two on a line. Card ranks A to 10 fill the lower tier. Bets are set in the control bar from 0.10 to 100.
