Online Casino Infinity Reels Slots
Online casino infinity reels slots feature a dynamic grid that grows with every winning spin, appending a new reel to the right side of the layout each time a win extends to the final visible reel. Online casino infinity reels slots have no fixed reel count. The grid starts at 3 or 4 reels and expands indefinitely as long as winning combinations keep forming. This guide dissects the Infinity Reels mechanic, draws a clear line between it and standard expanding reel formats, ranks the 10 most compelling Infinity Reels titles, and outlines strategic considerations for handling high volatility.

What Infinity Reels Means in Online Slots
Infinity Reels is a patented slot mechanic that adds a new reel to the grid after every winning spin, provided the rightmost reel contributes to the winning combination. Infinity Reels carries no theoretical upper limit on how many reels can appear during a single spin sequence. The reel count resets to its starting configuration after the winning chain ends.
ReelPlay, an Australian slot developer, invented and trademarked the Infinity Reels mechanic. ReelPlay released El Dorado Infinity Reels in November 2019 as the first slot to deploy the system. The initial grid measured 3 reels Ă— 4 rows. Landing 5 or more matching symbols triggered a respin, and if the new rightmost reel extended the win, another reel appeared. A win multiplier increased by +1 with each expansion.
NetEnt independently developed a parallel mechanic called InfiniReels around the same time. NetEnt released Gods of Gold InfiniReels in 2020, using a 3 Ă— 3 starting grid where 3 matching symbols (rather than 5) triggered expansion. The two companies reached a formal agreement acknowledging that each developed its mechanics independently and agreeing to protect their respective trademarks. Beyond the original creators, Relax Gaming, PG Soft, Yggdrasil, and Boomerang Studios have licensed or adapted the concept for their own titles.
How Infinity Reels Works: Step-by-Step
The Infinity Reels mechanic activates through winning spins rather than through bonus triggers. Each expansion is a free respin that costs the player nothing beyond the original bet.
- Place a bet on a starting grid of 3 or 4 reels. A single wager covers the initial layout.
- Spin the reels and land a qualifying win. ReelPlay's version requires 5 or more matching symbols. NetEnt's InfiniReels version requires 3 or more.
- Observe the grid expand. A new reel appears on the right side of the layout. The game awards a free respin on the enlarged grid.
- Check the new reel for contributing symbols. The expansion continues only when the new rightmost reel contains a symbol that extends or improves the existing win.
- Watch the multiplier climb. Each reel addition increases the win multiplier by +1. Starting at 1x, the multiplier reaches 2x after the first expansion, 3x after the second, and so on.
- Collect the payout when the chain breaks. The total win is calculated by multiplying the final combination value by the accumulated multiplier. The grid then resets to its starting size.
A worked example demonstrates the snowball effect. A $0.25 bet on Giza Infinity Reels lands 5 matching scarab symbols across the initial 3 reels. The grid expands to 4 reels. The new reel contains another scarab, extending the win. The multiplier climbs to 2x. A fifth reel appears with one more scarab. The multiplier reaches 3x. The sixth reel holds no scarab, ending the chain. The 7-symbol combination pays $1.80 at base value. The 3x multiplier triples it to $5.40 on a $0.25 stake, a 21.6x return.
Infinity Reels vs Expanding Reels: Key Differences
Infinity Reels and standard expanding reels both grow the grid during play, but the trigger conditions, expansion scope, and multiplier behavior diverge significantly.
| Feature | Infinity Reels | Standard Expanding Reels |
|---|---|---|
| Trigger | Win must extend to the rightmost reel | Various (bonus round, specific symbols, cascades) |
| Expansion direction | Adds reels to the right, one at a time | Adds rows, reels, or both, often in preset stages |
| Expansion limit | No theoretical cap (resets after chain ends) | Usually capped at a fixed maximum grid size |
| Multiplier | Increases by +1 with each added reel | Varies by game (often absent) |
| Cost per expansion | Free respin (no additional bet) | Usually free respins or part of bonus round |
| Starting grid | 3 Ă— 4 (ReelPlay) or 3 Ă— 3 (NetEnt) | Varies (5 Ă— 3, 5 Ă— 4, 6 Ă— 5) |
| Jackpot mechanic | 888x Infinity Bonus at 12+ reels (most titles) | Typically absent |
| Volatility tendency | High to very high | Medium to high |
Infinity Reels offers open-ended grid growth driven by consecutive wins. Standard expanding reels provide controlled, staged grid increases within predetermined boundaries.

Pros and Cons of Infinity Reels Slots
Online casino Infinity Reels slots offer 5 pros and cons for players evaluating the format.
| Aspect | Pros | Cons |
|---|---|---|
| Grid growth | Offers unlimited reel expansion with no theoretical cap on grid size | Resets the entire grid to the starting layout when the chain breaks, producing abrupt endings |
| Multiplier scaling | Builds a progressive multiplier (+1 per reel) that applies to the entire accumulated win | Requires long winning chains to reach meaningful multiplier levels, which occur infrequently |
| Value per spin | Generates free respins on every expansion, extracting multiple outcomes from a single bet | Concentrates almost all value in expansion chains, leaving non-expanding spins with minimal returns |
| Innovation | Introduces a unique sensation of open-ended growth unavailable in fixed-grid formats | Involves a learning curve that may confuse players accustomed to standard 5 Ă— 3 layouts |
| Jackpot layer | Awards a fixed 888x Infinity Bonus when the grid reaches 12+ reels on most titles | The 12-reel threshold triggers rarely, making the jackpot an aspirational feature rather than a reliable payout |
Tips for Playing Infinity Reels Slots
Six considerations shape a more informed approach to Infinity Reels gameplay.
- Verify the RTP and note the range across titles. Most ReelPlay Infinity Reels slots sit at 95.48% RTP. Odin and Tiki Megaways variants offer 96.07%. Gods of Gold InfiniReels offers 96.21%. The RTP difference across titles amounts to 0.7 percentage points, which compounds over hundreds of spins.
- Begin in demo mode to internalize the expansion rhythm. The Infinity Reels mechanic behaves unlike any fixed-grid slot. Play 30 to 50 spins in free play to observe how frequently expansions trigger and how deep the chains typically run before committing real funds.
- Distinguish between ReelPlay and NetEnt implementations. ReelPlay requires 5 matching symbols and starts on a 3 Ă— 4 grid. NetEnt requires 3 matching symbols and starts on a 3 Ă— 3 grid. The trigger threshold directly affects how often expansions begin.
- Allocate a bankroll suited to high volatility. Most Infinity Reels titles carry high to very high volatility. A $50 bankroll at $0.25 per spin covers 200 spins. Non-expanding spins return minimal value, so most session profit depends on a small number of deep expansion chains.
- Prioritize Megaways hybrids for maximum ceiling. Odin Infinity Reels Megaways (50,000x max win) and Tiki Infinity Reels Megaways (10,000x max win) combine reel expansion with variable symbol counts per reel. The combination multiplies the ways to win exponentially during expansion sequences.
- Track the 888x Infinity Bonus threshold. Reaching 12 reels on a single spin awards 888x the bet on most ReelPlay titles. The threshold is rare but worth monitoring, especially during free spins where multipliers do not reset between chains.
Summary
Infinity Reels is the slot mechanic that removes the upper boundary on grid size, appending a new reel and increasing a win multiplier with every consecutive winning spin. The format appeals to players drawn to open-ended growth, escalating multipliers, and the rare but dramatic prospect of grids stretching well beyond conventional reel counts.
Start with El Dorado Infinity Reels from ReelPlay for the purest implementation of the original mechanic, or Odin Infinity Reels Megaways for the highest ceiling when Infinity Reels and Megaways combine into a single slot. Both titles capture the core appeal of a format where the next reel is always one winning symbol away.

Are Infinity Reels slots available in demo mode?
Yes. Most online casinos offer Infinity Reels titles in free play or demo mode. Demo mode is particularly valuable for this mechanic because the expansion rhythm and multiplier behavior differ substantially from standard slot formats.
