There’s a fine line between slot machine developers and casinos marketing to children and marketing to the child inside all of us.

However, NJ online casinos manage to walk the line this time every year with a plethora of holiday-themed online slots because everyone loves Christmas. Most even manage to take just enough of a mature angle on the theme to avoid being accused of trying to attract players younger than 21.

Best of all, many of the holiday-themed games at NJ online casinos offer massive jackpots. Nothing beats the joy of giving, except maybe the joy of winning towering stacks of cash playing slots at NJ online casinos.

Start with this list of the best holiday-themed online slots that players can find all-year round on the best NJ online casino sites in the business:

Secrets of Christmas

Secrets of Christmas is a five-reel, 25-line Christmas-themed online slot with a jackpot of $400,000 just waiting to be won.

The theme has players sitting in a rustic cabin in a snowy winter wonderland experiencing the joys and rewards of the holiday season.

The game features a variety of familiar Christmas symbols like candles, gingerbread houses, cookies and milk, stockings, wreaths, and tree ornaments.

Plus, holiday classics dominate the soundtrack. The Santa Claus symbols are wild and the Scatter symbol is a box of toys.

Mostly, players spend their time helping Santa sort his gifts, but now and then the Christmas cheer is spread around when they find the Free Spins bonus and Wild Reels.

Three or more scatter symbols appearing anywhere on the reels trigger 10 free spins. But first, players get the chance to play a bonus game where they pick from 20 Christmas gifts to win various free spins bonus features. The amount of picks a player receives depends on the number of scatter symbols that appear.

The features available include:

• Anywhere from two to 10 additional free spins
• Multipliers
• Wild reels
• Additional wilds

The NetEnt-designed game launched worldwide in 2016 and is available at several NJ online casino sites, including Golden Nugget.

Jolly’s Gifts

Jolly’s Gifts is a five-reel, 40-line holiday-themed video slot with a hefty maximum payout of $250,000.

Picture snow falling lightly in the background, as Jolly and her animal friends spread a little Christmas cheer. This game also features a variety of familiar holiday symbols like gingerbread men, toy soldiers and Christmas gifts.

Plus, there are great bonus features like respins and wilds.

The Jolly’s Wild Respin appears randomly. All wins are paid and then the reels respin with a wild reel showing up at random. Wild reels then move one reel to the left and another respin is awarded.

Floating wilds appear after each wild reel movement and remain onscreen for a single respin only. The feature continues until the wild reel reaches the first reel.

The Free Games feature awards 12 free games when the Free Games symbols appear on three reels. Gift Box symbols are wild during free games.

Players trigger the Jolly’s Mystery Gifts feature when the gift box symbols appear stacked on all reels. A random symbol replaces all gift box symbols.

Game developer Side City Studios launched the online slot in 2017.

Jolly’s Gifts offers the players a chance to experience the joy of the season any time of year at a variety of NJ online casinos, including 888 Casino NJ.

Snowflakes

Snowflakes is a five-reel, 25-line online slot that’s more winter-themed, but with a $250,000 maximum payout, it’ll fit the holiday-themed bill here just fine.

The slot’s symbols are mostly snowflakes, and even though we all know that each snowflake is unique, the idea is still to match up similar ones. Find a block of ice and its wild, while the balls of ice represent the game’s scatter symbol.

Players can trigger two Snowflakes bonus games at any time. Plus, there’s a free spins bonus round.

Players trigger the Icy Wild feature randomly and it turns as many as five regular snowflake symbols wild.

Players randomly trigger the Wild Wind feature before their next spin. It puts up to five wild symbols on the reels as well.

Finally, the Frozen Wilds free games feature awards anywhere from seven to 15 free games. It hits when anywhere from three to five scatter symbols appear. Wilds are sticky during free spins, making this feature a rather lucrative one.

This NextGen-designed online casino slot may not scream out Christmas like the others on the list, but it’s certainly capable of spreading its share of holiday cheer.

It is available at a select number of NJ online casinos, including Resorts and Mohegan Sun.
