What Are Dynamic Reels in Slot Games?
Dynamic Reels is an advanced online slot mechanic which alters the initial layout of the machine. The adjustable reels change after a bonus feature activation or with every base game spin. They usually change the height of one or more reels, and thus add more paylines or ways to win into the mix. Often, the expanding grid is saved for the bonus minigame if there is one in the particular online slot.
There are several types of Dynamic Reels games, depending on how the mechanic is programmed to work. Megaways is the most popular slot engine using flexible reels, although several other providers have crafted similar mechanics with different names. I’ll provide more information about the Megaways way of functioning later, and for now let’s focus on a few examples for slots with variable reels.

Types of Dynamic Reels Slot Machines
Even with just a few examples, you probably noticed that there are various Dynamic Reels slots in terms of mechanics. What once was considered digital magic is now just another way to power up your slot machine. Still, we can divide games into several major categories when we discuss dynamic wins. And here they are explained in brief:
Megaways Slots
Megaways was invented by Big Time Gaming and first implemented in 2016 in the online slots Dragon Born and Bonanza. The classic variant has 6 reels with up to 7 symbols on each one and generates up to 117,649 ways. It is enhanced with chain reactions or mechanics also known as cascades, avalanches, drops, tumbles, etc.
Megaways evolved over the last decade and are now available on different board sizes. Besides the original, you will find the engine with 46656, 200704, 248832, 262144, and even millions of ways to win. Moreover, BTG released more advanced variants of the mechanic, labeling them MegaClusters and MegaPays. They transfer the Megaways basics in other online slot payout systems like clusters and paylines.
Expanding Reels
The Expanding Reels mechanic is less revolutionary but still quite an advanced add-on. It is usually added as part of bonus minigames like Hold & Win and Free Spins. If the grid is not automatically expanded, the rule is usually to complete certain tasks to unlock new rows. If part of the base game, reels may expand by landing special symbols or filling out all the symbol positions. In any case, the feature usually expands not just the board but also increases the basic ways to win or paylines.
Grid-Based Expansions
Besides vertically growing reels, some Dynamic Reels slots can expand to the left or to the right. These grid expansions are virtually unlimited and will continue for as long as certain rules apply. A good example is the Infinity Reels mechanic, which will continue to increase the number of reels on the right as winning combinations lengthen. In short, the grid-based expansions can be done in all directions, adding reels, rows, and symbol positions, and increasing the capacity of the board.
FAQ
What triggers dynamic reel expansion?
Expansions usually activate when predetermined terms are in place. For example, a minimum number of symbols, the presence of special symbols, formation of winning combinations, cascades, and others.
Can reels shrink as well as expand?
Both expansions and contractions are possible in multi-way online slots. A good example is the Megaways mechanic, where reels can have from 2 to 7 symbols, and the grid alters in size on every spin.
Do Dynamic Reels increase chances of winning?
This mechanic is developed to increase the tension and quality of entertainment. Indeed, systems like Megaways and TrueWays increase the ways to win many times over. But the payout potential of an online slot is based on many factors, and the payout system is just one of them.
