In this guide, we talk about some of the most profitable online slot games in Norway as of 2025. Not only do these titles promise fantastic entertainment, but they also possess great payout potential for fortunate players. Following is our carefully curated compilation of the best paying 5 slots based on RTP, users' ratings, and game features.

1. Millionaire Genie – RTP 96.00%

Millionaire Genie is an old-school online slot with a proven track record of delivering life-changing jackpots. Developed by Section 8, a special 888 Casino provider, this slot has enchanted users with its magical Arabian theme and potential to win massive amounts of up to €500,000.

Part of what makes Millionaire Genie so attractive is the array of bonus features that it offers, including free spins, sticky wilds, and interactive mini-games. There is even a Megaways variant of this game with 117,649 ways to win. The UK's biggest prize for this game was a whopping £2.4 million, and an Italian player once bagged over €870,000. Given the slot's offbeat design and frequent payouts, the slot remains a favourite among players hunting for big rewards.

2. Mega Joker – RTP 99.00%

NetEnt's Mega Joker might be among the most known and profitable slots today, thanks to its whopping RTP of 99%. As high as this return is, it's no surprise that enthusiasts are drawn to this classic fruit-based slot.

Despite its retro graphics and simple design, Mega Joker is high-stakes gaming with a high degree of volatility. That means the wins come less often but bigger when they do arrive. The Supermeter mode adds even more excitement to the game because players can end up triggering enormous wins. It's no surprise that the game continues to be one of the top-ranking slots in Norway and the rest of Europe.

3. 1429 Uncharted Seas – RTP 98.60%

Thunderkick's 1429 Uncharted Seas transports players to the Age of Exploration in a beautifully rendered nautical-themed game. The game's graphics are reminiscent of ancient sea charts, and the atmospheric score completes the feeling of discovery.

The 98.60% RTP and low volatility are the reasons why this slot is ideal for players who want guaranteed wins without having to spend much money. The bonus features include expanding wilds and 50 free spins. Such features, together with its innovative design, make 1429 Uncharted Seas the ideal game for players looking to play for fun but be lucrative.

4. Book of 99 – RTP 99.00%

Book of 99 is Relax Gaming's Greek mythology-themed slot that stands out as a class of its own among "book-style" slots. Its record-breaking RTP of 99% gives it one of the highest theoretical returns in the online gaming industry.

Book of 99 stands apart from others by having an innovative bonus system. Players can gain book symbols over time—regardless of whether they spin three of them per round—until they reach 99 books and trigger 10 free spins. This gives a sense of progress and rewards loyalty. The slot also includes expanding symbols during free spins for even bigger win potential. If you’re a fan of games like Book of Dead but want something fresher and more rewarding, this is your go-to option.

5. Divine Fortune – RTP 96.59%

NetEnt’s Divine Fortune brings the magic of Greek mythology to the reels with stunning visuals and rewarding gameplay. This 5x3 slot features 20 paylines and several engaging bonus mechanics, including Wild-on-Wild expanding symbols, re-spins, and falling wilds.

The highlight of the game is the Mega Jackpot, one of three jackpots. With Minor, Major, and Mega jackpots, players never go without a chance to take home big prizes. Divine Fortune also comes in a Megaways variation with even greater winning possibilities due to the dynamic reel layout. It is therefore one of Norway's best online slots for high rollers.
