Infinity Reels Slots - What are they and why are they becoming so popular
Could the creator of the original one-armed bandit have imagined that slot design would one day reach online games without fixed pay lines, offering countless ways to win and reels that can keep expanding?
It seems unlikely that Charles August Fey, credited with inventing the first slot machine, foresaw how his creation would shape iGaming. The first airplane had yet to be invented, while the internet and World Wide Web were still far in the future.
Just 24 months ago, most online slots players and developers had not encountered the infinity reels idea. That changed in the final month of 2019, when Reel Play launched what described as the first Infinity Reels video slot, El Dorado Infinity Reels.
How do Infinity Reels Slots Work?
A handful of rounds is usually enough to see the basic Infinity Reels mechanic in action. Its rules are straightforward, even if the effect is unusual.
- Each winning combination adds 1 new reel
- A free spin follows, and only the reel just added spins; the other reels stay in place
- If the reel spun in step 2 makes the earlier win bigger, the game adds another reel. You then receive another free spin on that new reel alone, while the others hold
- This reel-adding sequence can repeat an infinite number of times, stopping when a new spin does not improve the previous win
In short, an improved result brings another reel into play, and the cycle may continue an infinite number of times. That open-ended growth explains the name ‘Infinity Reels’. The example below shows a game that begins with 3 reels.
- Spin 1: Start with 3 reels; add 1 after a win
- Spin 2: There are 4 reels; add 1 after a win
- Spin 3: There are 5 reels; add 1 after a win
- Spin 48: There are 50 reels; add 1 after a win
How do Infinity Reels Pay Players?
Each new spin also records its win separately. For example, if a previous result of 3 Ace symbols paid a 5x multiplier and the next spin formed 4 Ace symbols worth 10x, the game adds that 10x to the earlier 5x. The accumulated total at that point is 15x.
- Spin 1: A x5 multiplier win (Total: x5)
- Spin 2: A x10 multiplier win (Total: x15)
- Spin 3: A x20 multiplier win (Total: x35)
How Does the Infinity Reels Feature Combine with Infinite Megaways?

Tiki Infinity Reels Megaways and Odin Infinity Reels Featuring Megaways are the video slot titles identified here as combining ‘Megaways’ mechanics with ‘Infinity Reels’. If you know Megaways slots and their changing reel shapes, this pairing brings that shifting layout together with reels that can be added after wins.
Infinity Reels Megaways slots start with 3 reels, each able to show between 2 and 7 symbols. After a win, the first 3 reels stay in place and a newly added 4th reel spins. Like the other Megaways reels, this 4th reel can land between 2 and 7 symbols. 115,000 ways to win is described as the traditional total once play goes beyond 6 reels. Further wins can extend the sequence with 7, 8, 9, and 10 reels, allowing the possible ways to win to keep increasing without a set limit.
What Infinity Reels Titles Are Online?

The article lists ‘Infinity Reels’ games among casinos with Yggdrasil games. Yggdrasil had not yet released an Infinity Reels game under its own name at the time described. Reel Play instead worked with Bad Dingo, BB Games, Royal Dragon, and Boomerang Studios on branded releases delivered through the YG Masters game system. Examples named here include Gems Infinity Reels, Martian Miner Infinity Reels, Golden Haul Infinity Reels, Gargoyle Infinity Reels, Olympus Infinity Reels, Crystal Wolf Infinity Reels, Royal Dragon Infinity Reels, and Thor Infinity Reels, along with the 2 Reel Play Infinity Reels Megaways titles discussed above.
Other studios mentioned include Relax Gaming, whose title is Emerald’s Infinity Reels, and PG Soft, with Buffalo Win Infinity Reels, Secrets of Cleopatra Infinity Reels, Jack Frost’s Winter Infinity Reels, and Bali Vacation Infinity Reels.
The name Infinireels also appears on games from NetEnt and RedTiger. The article lists 1 title from each studio using the feature: NetEnt’s Gods of Gold Infinireels and Red Tiger’s Dragons Fire Infinireels. The source anticipated that both brands might add more Infinireels games as interest in the feature grew.
