This page gives you instant access to free Infinity Reels slots — playable directly in your browser with no download, no deposit, and no registration required. Every game listed here uses the Infinity Reels mechanic developed by ReelPlay: the reel grid expands horizontally each time a winning symbol lands on the rightmost reel, adding a new reel to the right and continuing until no new winning combination can form. The mechanic is fully active in demo mode, so you can watch the reel set grow in real time before committing to a real-money session.
Infinity Reels is a niche mechanic by current catalogue standards — fewer than twenty titles currently use it — which makes this page a complete reference rather than a filtered subset. Every available Infinity Reels slot is listed here, with demo access to all of them.
Every Infinity Reels slot above launches instantly in your browser — no account, no software, no deposit. Click any game and the demo opens directly on desktop, Android, or iOS. The reel expansion mechanic is fully active: when a winning symbol lands on the rightmost reel, a new reel is added in real time, exactly as it would in a paid session. Multipliers climb, jackpot thresholds count down, and free spins trigger normally.
Because the Infinity Reels catalogue is compact — under twenty titles across all providers — demo play here gives you access to the complete mechanic landscape rather than a curated subset. For the latest Infinity Reels releases, see our new slots page.
Infinity Reels is an expanding reel mechanic developed by ReelPlay. Unlike fixed-reel slots where the grid dimensions are set before the spin begins and never change, an Infinity Reels game starts with a compact reel set and grows outward during the spin itself — adding new reels to the right each time a winning combination extends to the current rightmost reel.
The name reflects the mechanic's theoretical ceiling: there is no fixed limit to how many reels can be added in a single spin sequence. In practice, a spin that keeps producing rightmost-reel wins can extend the grid to twelve or more reels before the chain breaks — and in titles with an Infinity Jackpot, reaching twelve reels triggers a fixed prize on top of the accumulated win. The mechanic is designed around the idea that a winning spin is not a closed event but a starting point for further expansion.
From a player's perspective, the defining quality of Infinity Reels is momentum. A spin that starts well keeps building — each new reel added is both a win confirmation and an opening for the next one. That escalating structure is what separates it from both standard fixed-reel play and cascade mechanics, where winning symbols are removed and replaced rather than retained and extended.
The full sequence plays out within a single paid spin — no additional bets are required as reels expand.
The key distinction from cascade mechanics is that existing winning symbols are not removed during the expansion — they remain on the grid while only the new rightmost reel spins fresh symbols. This means the winning combination that triggered the first expansion is still intact and visible when the second, third, and fourth reels are added. The grid grows outward while the original win is preserved, which creates a visually distinct and escalating session feel that cascades do not replicate.
When NetEnt released their Infinireels mechanic in 2020, there was widespread confusion between the two expanding reel systems. Both involve reels that grow when winning combinations land — but the implementations are different enough that understanding the distinction matters before testing either in demo mode.
| Feature | Infinity Reels (ReelPlay) | Infinireels (NetEnt) |
| Developer | ReelPlay (licensed to other studios) | NetEnt (proprietary) |
| Expansion trigger | Winning symbol must land on the current rightmost reel | Any win on any reel triggers expansion |
| Minimum symbols for expansion | Five or more matching symbols in the winning combo | Three matching symbols |
| Spin cost during expansion | Free — all reel additions occur within the original paid spin | Each expansion requires an additional bet |
| Multiplier behavior | Optional — present in some titles, carries into free spins | Varies by title |
| Jackpot trigger | Present in some titles — reaching 12 reels awards Infinity Jackpot | Not a standard feature |
| Notable titles | Thor Infinity Reels, Zodiac Infinity Reels, Odin Infinity Reels | Divine Fortune Megaways |
The most significant practical difference is the spin cost. In NetEnt's Infinireels, the player pays an additional bet for each expansion step — so an extended chain of expansions has a compounding cost. In ReelPlay's Infinity Reels, the entire expansion sequence is contained within the single original paid spin. No additional bet is required regardless of how many reels are added. That difference changes the risk math of the mechanic significantly and is worth understanding before evaluating demo play results in either system.
The base Infinity Reels mechanic — wins extend the grid, expansion continues until the chain breaks — is consistent across all titles. What varies between games is the secondary feature layer built on top of that base. These additions change the risk profile, the maximum win ceiling, and the session rhythm in ways that are clearest when tested in demo mode.
The core expansion mechanic is the same in every title — these additions change what happens during and after the expansion chain.
Each reel added during an expansion chain increments the win multiplier. In Zodiac Infinity Reels, this multiplier carries into free spins and does not reset between bonus spins — meaning a free-spin session that triggers mid-expansion starts with the accumulated multiplier already applied.
In Thor Infinity Reels and El Dorado Infinity Reels, reaching twelve reels in a single expansion chain triggers the Infinity Jackpot — a fixed prize worth 888x the triggering stake. This is awarded on top of any wins accumulated during the expansion sequence.
Tiki Infinity Reels and Odin Infinity Reels combine the Infinity Reels expansion mechanic with the Megaways variable-reel-height system. Each reel in the expanding grid displays a variable number of symbols on each spin, changing the ways-to-win count dynamically. This stacks the reel-expansion tension with Megaways' ways-count volatility.
Martian Miner Infinity Reels expands downward rather than horizontally. New rows are added to the bottom of the grid when a winning symbol lands on the bottom row. This is the only directional variant in the current Infinity Reels catalogue and produces a different visual rhythm from horizontal expansion.
Most Infinity Reels titles include a scatter-triggered free spins round. The expansion mechanic and any accumulated multiplier remain active during free spins. Because the multiplier does not reset between bonus spins, the later spins in a free-spin sequence pay at progressively higher multiplier values if expansion chains have occurred.
Hypernova Infinity Reels Dream Drop adds the Relax Gaming Dream Drop progressive jackpot network to the Infinity Reels mechanic. Five jackpot tiers — Midi, Maxi, Major, Mega, and Rapid — can trigger randomly during any spin, independent of the reel expansion sequence.
With under twenty titles in the complete Infinity Reels catalogue, every available game is worth knowing. These six represent the most distinct implementations of the mechanic — each one uses the core expansion logic in a different way, making side-by-side demo comparison the most efficient way to identify which variant suits your preferred session style.
| Slot | Developer | Expansion Direction | Multiplier | Jackpot | Additional Mechanic | Best For |
| Thor Infinity Reels | ReelPlay | Horizontal | Yes — per reel added | Infinity Jackpot at 12 reels (888x) | Free spins | Players who want jackpot target + multiplier in one game |
| Zodiac Infinity Reels | ReelPlay | Horizontal | Yes — carries into free spins, no reset | No | Free spins with persistent multiplier | Players testing the multiplier carry-over mechanic |
| Odin Infinity Reels Megaways | ReelPlay | Horizontal | Yes | Infinity Jackpot | Megaways variable reel height | Players who want Infinity Reels + Megaways combined |
| Martian Miner Infinity Reels | ReelPlay | Vertical (downward) | Yes | No | Unique downward expansion | Players who want the directional variant of the mechanic |
| Hypernova Infinity Reels Dream Drop | ReelPlay / Relax Gaming | Horizontal | Yes | Dream Drop progressive (5 tiers) | Network progressive jackpot | Players who want a progressive jackpot attached to Infinity Reels |
| El Dorado Infinity Reels | ReelPlay | Horizontal | Yes | Infinity Jackpot at 12 reels (888x) | Free spins | Players comparing the jackpot trigger across different themes |
The Infinity Jackpot is the maximum win condition built into several Infinity Reels titles. It triggers when a single expansion chain reaches twelve reels in the same spin sequence — meaning the rightmost reel has produced a contributing winning symbol eleven consecutive times, adding one new reel each time. When the twelfth reel is added and contributes to a win, the Infinity Jackpot is awarded: a fixed prize worth 888x the triggering stake.
This is awarded on top of — not instead of — the accumulated win from the expansion chain. A twelve-reel sequence that has also generated a large win from the expanding combination receives both the combination payout and the 888x jackpot. The two are independent.
Titles that include the Infinity Jackpot: Thor Infinity Reels, El Dorado Infinity Reels, and Odin Infinity Reels. Titles with the Dream Drop progressive — such as Hypernova Infinity Reels Dream Drop — use a separate jackpot network that triggers independently of the reel count. For a broader overview of jackpot slot structures, see our jackpot slots page.
Two titles in the current Infinity Reels catalogue combine the mechanic with the Megaways engine: Tiki Infinity Reels and Odin Infinity Reels. The combination stacks two independently variable elements within the same spin.
In a standard Megaways slot, each reel displays a variable number of symbols (between two and seven) on every spin, producing a different ways-to-win count on each result. In an Infinity Reels slot, the number of reels itself is variable — the grid grows with each expansion. In a title that combines both, every reel in the expanding grid also has a variable height. The result is a game where both the grid's width and each column's height change within the same spin sequence.
The practical effect is a substantially wider range of possible ways-to-win counts compared to either mechanic alone. When an expansion chain adds a new reel, that reel's height is also randomised — contributing a variable number of symbols to the growing combination. This makes the Infinity Reels Megaways titles the highest-complexity entries in the catalogue, and the ones where demo play provides the most information before a real-money session, since the interaction between grid-width changes and reel-height changes is genuinely difficult to visualise without seeing it resolve in real time.
ReelPlay developed and owns the Infinity Reels mechanic. As the originating studio, all Infinity Reels titles carry the ReelPlay brand — either as the primary developer or as the mechanic licensor in partnership titles. ReelPlay has also licensed the mechanic to other studios, which has expanded the catalogue beyond their own productions.

The Infinity Reels catalogue is deliberately compact — ReelPlay has not mass-licensed the mechanic, and the total number of available titles is under twenty. If you enjoy the expansion dynamic but want a larger selection of games to choose from, several related mechanics produce a comparable session feel through different structural approaches.

Infinity Reels is one of the most structurally distinctive mechanics in the current slot catalogue. The expanding grid does not just change win size — it changes the physical dimensions of the game in real time, turning a single paid spin into an escalating sequence where every successful reel addition opens the next possibility. That compounding momentum is genuinely different from both cascade mechanics and fixed-reel multiplier games, and it is the property that makes Infinity Reels worth testing in demo mode even if expanding reels are not your default preference.
With under twenty titles available, the practical recommendation is simple: start with Zodiac Infinity Reels to see the multiplier carry-over mechanic in its clearest form, then test Thor Infinity Reels or El Dorado Infinity Reels to understand how the twelve-reel jackpot threshold changes the session dynamic. If you want the highest-complexity version of the mechanic, Odin Infinity Reels Megaways combines grid expansion with variable reel height — a combination that demo play makes understandable in a way that a description does not. The catalogue is small enough that testing four or five titles covers the full range of what Infinity Reels currently offers.

Infinity Reels is an expanding reel mechanic developed by ReelPlay. The game starts with a compact reel set and adds new reels to the right each time a winning symbol lands on the current rightmost reel. The expansion continues until the newest reel produces no winning contribution. All reel additions occur within the same paid spin — no additional bets are required. The mechanic has no fixed ceiling on how many reels can be added, though in practice the Infinity Jackpot triggers at twelve reels in titles that include it.
A win lands and is evaluated. If a matching symbol is present on the rightmost reel, a new reel is added to the right and spins fresh symbols. If those symbols contribute to the existing winning combination, another reel is added. Each new reel that contributes a win also increments the multiplier (in titles with that feature). The sequence continues until a new reel produces no winning symbols, at which point the total accumulated win is paid.
Infinity Reels is ReelPlay's mechanic; Infinireels is NetEnt's separately developed system. Both expand reels on wins, but the key differences are: Infinity Reels requires a winning symbol on the rightmost reel specifically to trigger expansion (Infinireels expands on any win); Infinity Reels expansion occurs for free within the original spin (Infinireels charges an additional bet per expansion); Infinity Reels requires five or more matching symbols in a combo (Infinireels requires three). The two studios developed their mechanics independently.
The Infinity Jackpot is a fixed prize of 888x the triggering stake, awarded when an expansion chain reaches twelve reels in a single spin sequence. It is available in Thor Infinity Reels, El Dorado Infinity Reels, and Odin Infinity Reels. The jackpot is paid on top of the accumulated win from the expansion chain, not instead of it. Reaching twelve reels requires eleven consecutive rightmost-reel wins — observable in demo play but rare in any single session.
Yes. Every Infinity Reels slot on this page is available in demo mode — no deposit, no registration, no download required. The full expansion mechanic, increasing multipliers, jackpot threshold, and free spins are all active in demo play. You cannot win or lose real money in demo mode.
Zodiac Infinity Reels is the clearest starting point for understanding the multiplier carry-over mechanic. Thor Infinity Reels or El Dorado Infinity Reels show you the jackpot threshold in action. If you want to see the directional variant, Martian Miner Infinity Reels expands downward rather than horizontally. For the highest complexity version combining Infinity Reels with Megaways, test Odin Infinity Reels Megaways — but read the paytable before starting so you understand how both mechanics interact.
The current catalogue contains under twenty titles across all providers using the mechanic. ReelPlay developed the majority directly; PG Soft, BB Games, Boomerang Studios, and Relax Gaming have also produced titles using the licensed mechanic. The catalogue is significantly smaller than other proprietary slot mechanics such as Megaways, which has hundreds of licensed titles across dozens of studios.
Most Infinity Reels titles include a scatter-triggered free spins round. The expansion mechanic is active during free spins, and in titles with an increasing multiplier the multiplier does not reset between bonus spins — meaning later spins in the bonus sequence pay at progressively higher multiplier values if expansion chains have occurred earlier in the round. The free spins bonus is fully accessible in demo mode.
In cascading slots, winning symbols are removed from the grid and replaced by new ones dropping in — the grid dimensions stay the same throughout the spin. In Infinity Reels, winning symbols are retained in place and the grid itself grows outward by adding new reels. The expansion adds new positions rather than refilling existing ones. The result is a visually and structurally distinct experience: in cascades the grid refills, in Infinity Reels it extends.
