Infinity Reels Slots: What They Are and Why They Are Becoming Popular
Could the inventor of the original one-armed bandit have imagined that slot design would reach online games with no fixed pay lines, countless ways to win and reels that can keep growing?
Charles August Fey, credited with inventing the first slot machine, is unlikely to have predicted how his creation would influence iGaming. The first airplane had not yet been invented, and the internet and World Wide Web were still far off.
Only 24 months earlier, most online slot players and developers had not encountered the infinity reels concept. That changed in the final month of 2019, when Reel Play released what it described as the first Infinity Reels video slot, El Dorado Infinity Reels.
How Do Infinity Reels Slots Work?
A few rounds are usually enough to demonstrate the basic Infinity Reels mechanic. The rules are simple, even if the gameplay looks unusual.
- Every winning combination adds 1 reel
- A free spin follows, spinning only the newly added reel while all the other reels remain in place
- If the reel spun in step 2 increases the previous win, another reel is added. You get another free spin on that new reel alone while the others stay put
- The reel-adding cycle can repeat an infinite number of times, ending when a spin fails to improve the previous win
Put simply, a better result adds another reel, and the cycle may continue an infinite number of times. That potential for ongoing expansion gives the feature its name, ‘Infinity Reels’. The example below starts with 3 reels.
- Spin 1: Begin with 3 reels; a win adds 1
- Spin 2: Now there are 4 reels; a win adds 1
- Spin 3: Now there are 5 reels; a win adds 1
- Spin 48: Now there are 50 reels; a win adds 1
How Do Infinity Reels Pay Players?
Wins from each new spin are recorded separately and then added together. For example, a previous win of 3 Ace symbols might pay a 5x multiplier, while the next spin forms 4 Ace symbols worth 10x. The game adds that 10x to the earlier 5x, bringing the accumulated total to 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 Infinity Reels Work with Infinite Megaways?

Tiki Infinity Reels Megaways and Odin Infinity Reels Featuring Megaways are the titles identified here as blending ‘Megaways’ mechanics and ‘Infinity Reels’. Players familiar with Megaways slots and their changing reel layouts can see how this combination adds reels after wins to an evolving layout.
Infinity Reels Megaways slots begin with 3 reels, each displaying 2 to 7 symbols. After a win, the first 3 reels remain in place while a newly added 4th reel spins. Like the other Megaways reels, the 4th can land with 2 to 7 symbols. The article describes 115,000 ways to win as the traditional total once play passes 6 reels. Further wins can add 7, 8, 9 and 10 reels, letting the possible ways to win grow without a fixed limit.
Which Infinity Reels Games Are Online?

The article identifies ‘Infinity Reels’ games among casinos with Yggdrasil games. At the time covered, Yggdrasil had not released an Infinity Reels game under its own name. Instead, Reel Play partnered with Bad Dingo, BB Games, Royal Dragon and Boomerang Studios on branded titles distributed through the YG Masters game system. Examples listed 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, plus the 2 Reel Play Infinity Reels Megaways titles discussed above.
Other studios in the article include Relax Gaming, with 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 Infinireels name also appears on games by 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. It anticipated that both brands could release more Infinireels games as interest in the feature increased.
