For most of their history, pokies had a fixed shape. Five reels, three rows and a set number of paylines meant every spin offered the same number of ways to win. Variable reel games broke that rule. In these titles, the height of each reel changes from spin to spin, so the number of possible winning combinations can jump from a few hundred to well over one hundred thousand and back again.
Game guides such as https://thepokiescasinoau.com list variable reel titles alongside their maximum ways to win and volatility ratings, and the format now appears in the catalogues of dozens of studios. This article explains how the mechanic works, why it changes the feel of a game so dramatically, and what to check before you play one.
The Basic Mechanic
In a standard pokie, each reel shows the same number of symbols on every spin. In a variable reel game, each reel can show a different number of symbols, typically anywhere from two to seven. A six-reel game might land with three symbols on the first reel, seven on the second, five on the third and so on.
Wins are counted on a “ways” basis. Matching symbols on adjacent reels, starting from the leftmost reel, form a win regardless of which row they occupy. The total number of ways on any given spin is calculated by multiplying the number of symbols on each reel. If six reels show 7, 7, 7, 7, 7 and 7 symbols, the spin offers 117,649 ways to win. If they show 2, 3, 2, 4, 2 and 3, the spin offers only 288.
The best-known version of this idea was developed by Big Time Gaming under the Megaways name and later licensed to many other studios. Similar systems now exist under various names, but the core principle is the same.
Why the Number of Ways Changes Everything
The changing grid creates a very particular rhythm. Spins with few ways tend to pay little, while spins with many ways can produce several overlapping wins at once. This unpredictability is a large part of the format’s appeal, because every spin starts with a moment of anticipation as the reel heights are revealed.
| Reel heights (six reels) | Ways to win | Typical experience |
|---|---|---|
| 2, 2, 2, 2, 2, 2 | 64 | Very few combinations, small or no wins |
| 3, 4, 3, 4, 3, 4 | 1,728 | Moderate chance of a win |
| 5, 5, 5, 5, 5, 5 | 15,625 | Frequent overlapping wins |
| 7, 7, 7, 7, 7, 7 | 117,649 | Maximum ways, rare but exciting |
It is important to understand that more ways does not automatically mean better value. The game’s maths model accounts for the full range of reel heights, and the overall return to player is fixed regardless of how many ways appear on any individual spin.
Common Companion Features
Variable reel games rarely rely on the changing grid alone. Most combine it with other mechanics that build on the high number of possible combinations:
- Cascading reels, where winning symbols disappear and new ones drop into place
- Horizontal reels above the main grid that add extra symbols to several reels at once
- Unlimited win multipliers that increase with each cascade during free spins
- Mystery symbols that all transform into the same random symbol
- Free spins rounds where reel heights are locked at a higher minimum
The combination of cascades and growing multipliers is particularly common. During free spins, each successive cascade may raise the multiplier by one, so a long chain of wins can produce a substantial result. This is also where much of the game’s value is concentrated.
Volatility in Variable Reel Games
Because so much depends on reel heights, cascades and multipliers lining up, variable reel games are usually medium-high to high volatility. A session might include long stretches of small or no wins, followed by a sudden burst when the grid opens up and cascades start chaining together.
For players, this means two practical things. First, a modest budget can run out before the most rewarding features appear. Second, it helps to choose a smaller stake than you might on a low-volatility game, so that you have enough spins to experience the game properly. Treating variable reel titles as an occasional change of pace, rather than a default choice, is a sensible approach for many players.
Reading the Rules Before You Play
The information screen in a variable reel game is worth more attention than usual. It should explain the minimum and maximum reel heights, how the horizontal reel works if there is one, how cascades and multipliers behave in the base game and during free spins, and how many scatters are needed to trigger the feature.
Check the maximum win as well. Many variable reel games offer very large theoretical maximums, often expressed as tens of thousands of times the stake. These figures are possible but extremely rare, and they should not shape your expectations for a typical session. The published RTP is a better guide to the game’s overall cost of play.
Why the Format Became So Popular
Variable reel games arrived at a time when many players felt that traditional video pokies had become predictable. The changing grid made each spin feel different, and the huge headline number of ways was easy to promote. Studios embraced the format because it could be combined with almost any theme, from ancient myths to modern game shows.
The format also suits mobile play surprisingly well. Although the grid can become dense, clear symbol design and animated cascades keep the action readable on smaller screens. That flexibility helped variable reel games become a staple across both desktop and mobile catalogues.
Variable Reels Compared With Fixed Layouts
It is worth thinking of variable reel games as one style among many rather than an upgrade on older formats. Fixed-line games offer a steadier and more predictable experience, which many players prefer for longer, more relaxed sessions. Variable reel games trade that steadiness for excitement and swings. Neither is objectively better; the right choice depends on your budget, your patience and what you find enjoyable.
Final Thoughts
Variable reel pokies are one of the most significant design changes in the modern era of the game. By letting the number of ways to win shift from spin to spin, they create a distinctive mix of anticipation and volatility.
