Megaways, Cluster Pays and Hold and Win

Stylized slot reels with changing symbol heights

Modern slot games do not all calculate wins in the same way. Megaways changes how many symbols appear on each reel, Cluster Pays rewards connected groups instead of traditional paylines, and Hold and Win locks value symbols in place during a respin feature.

Although these mechanics are often grouped together, they work very differently. This guide explains how each system forms wins, which additional features are commonly included and what to check in a game’s paytable before playing.

The exact rules, return to player, volatility and maximum win always depend on the individual title. The result of every paid spin is determined independently by the game software, as explained in our guide to how random number generators work.

Why Modern Slots Use Different Win Systems

Traditional slot games normally use a fixed reel layout and a defined number of paylines. A winning combination forms when matching symbols land in the required positions along one of those lines.

Modern developers use alternative systems to change how symbols appear and how combinations are counted. These mechanics can affect the pace and presentation of a game, but they do not automatically produce:

  • A higher RTP
  • More frequent wins
  • Lower volatility
  • A larger maximum payout
  • Better odds for the player

The mathematical model still determines the probability and value of every outcome. A traditional payline slot can therefore offer a higher RTP or maximum win than a Megaways, Cluster Pays or Hold-and-Win title.

How Megaways Works

Megaways is a slot engine developed by Big Time Gaming and licensed to numerous game studios. Its defining feature is a dynamic reel layout in which the number of visible symbols can change from one spin to the next.

In the familiar six-reel configuration, each reel may display between two and seven symbols. When all six reels display seven symbols, the game can provide up to 117,649 ways to win.

That figure is the maximum used by many classic Megaways titles. It does not apply to every spin or every game carrying the Megaways name.

How Megaways Calculates Ways to Win

The number of available ways is calculated by multiplying the active symbol positions on each reel.

For example, a layout displaying 3, 4, 3, 5, 4 and 2 symbols creates:

3 × 4 × 3 × 5 × 4 × 2 = 1,440 ways to win

Winning combinations usually require matching symbols to appear on adjacent reels, beginning with the leftmost reel. However, the exact direction and any exceptions are defined in the game’s paytable.

The displayed ways count represents the number of possible symbol combinations across the active reel layout. It is not the probability of receiving a winning result on that spin.

Cascades, Extra Reels and Multipliers

Many Megaways games add other features to the changing reel structure.

A cascade removes symbols involved in a winning combination and allows new symbols to fall into the empty positions. This can produce another result without requiring a separate paid spin.

Other titles may include:

  • An additional horizontal reel
  • Free-spin rounds
  • Increasing multipliers
  • Expanding wild symbols
  • Mystery symbols
  • Feature-buy options

These are supporting features rather than universal Megaways rules. Check whether the selected game uses cascades, how its extra reel affects combinations and whether feature multipliers reset or continue between reactions.

What 117,649 Ways Does Not Mean

Having more ways to win does not guarantee more frequent or more valuable payouts.

The developer still controls the game’s mathematical model, including symbol weighting, reel behaviour, payout values and bonus frequency. Two games offering the same maximum number of ways can therefore have very different RTP, volatility and hit-frequency figures.

How Cluster Pays Works

Cluster Pays replaces traditional paylines with connected groups of matching symbols.

Instead of requiring symbols to align across fixed reels, a win forms when enough identical symbols connect on the game grid. Many cluster games count horizontal and vertical connections but exclude diagonal ones.

A common minimum is five connected symbols, although the required cluster size depends on the individual game. Larger clusters often produce higher payouts, but the grid dimensions, connection rules and prize values are game-specific.

Cascades and Tumbles

Cascades—sometimes called tumbles or avalanches—are common in Cluster Pays games.

After a winning cluster is counted, its symbols disappear and new ones enter the grid. Those replacement symbols may form another cluster during the same paid spin.

The sequence normally continues until no new winning cluster appears. Some games also increase a multiplier or activate another modifier during consecutive cascades.

However, cascades are not required for a game to use Cluster Pays. The paytable should explain:

  • How many symbols are needed to form a cluster
  • Whether diagonal connections count
  • When a cascade sequence ends
  • Whether multipliers increase during the sequence
  • Whether modifiers reset after the spin

Collection Meters and Expanding Grids

Some cluster games collect removed symbols in a meter. Reaching a particular threshold may activate an additional feature, such as:

  • Adding wild symbols
  • Removing a low-value symbol
  • Increasing a multiplier
  • Expanding the playing grid
  • Upgrading symbol values

These features can affect later cascades, but they are optional additions rather than defining elements of the Cluster Pays mechanic.

How Hold and Win Works

Hold and Win commonly describes a respin feature built around special value symbols, such as coins, cash symbols or orbs.

When the feature begins, qualifying symbols remain locked in their positions while the remaining spaces respin. The objective is normally to land additional value symbols before the available respins run out.

Similar mechanics may be called Hold and Spin, Lock and Win, Money Respin or Jackpot Respin, depending on the developer and game. Because this terminology is not standardized, players browsing the Spino crypto casino should check each game’s paytable rather than assume that similarly named features follow identical rules.

Trigger and Respin Counter

Many Hold-and-Win features begin with three respins. Each new qualifying symbol may reset the counter, giving the player additional opportunities to fill the remaining positions.

This is a common structure, not a universal rule. Depending on the title:

  • The trigger may require three, five, six or another number of symbols.
  • The feature may begin with three or four respins.
  • A new symbol may reset or add to the counter.
  • Certain symbols may activate modifiers or additional prizes.
  • The feature may end under a separate stated condition.

The trigger, starting counter and reset behaviour should always be confirmed in the game’s information panel.

Value Symbols and Full-Grid Awards

Locked symbols often display values expressed as multiples of the stake. At the end of the feature, the game may add those values together to calculate the award.

Some titles also include:

  • Collector symbols
  • Multipliers
  • Extra-life symbols
  • Mini, minor, major or grand prizes
  • Full-grid awards
  • Additional wheels or bonus rounds

Filling every position may award the highest prize in one game but produce a different result in another. Jackpot names and qualification rules are not standardized across every Hold-and-Win title.

Megaways vs Cluster Pays vs Hold and Win

The main difference is the role each mechanic plays in the game.

Megaways

Megaways changes the number of symbols displayed on each reel. Winning combinations are generally counted through adjacent-reel ways rather than fixed paylines.

Before playing, verify:

  • The maximum number of ways
  • The required win direction
  • Whether cascades are included
  • How extra reels affect combinations
  • How multipliers behave during bonus rounds

Cluster Pays

Cluster Pays creates wins from connected groups of matching symbols on a grid.

Before playing, verify:

  • The minimum cluster size
  • Which connection directions count
  • Whether diagonal symbols connect
  • Whether winning symbols cascade
  • How meters and multipliers operate

Hold and Win

Hold and Win locks qualifying value symbols while the remaining positions respin.

Before playing, verify:

  • The number of symbols needed to trigger the feature
  • The starting number of respins
  • What resets or increases the counter
  • How locked values are calculated
  • What happens when the grid is filled

A game can also combine these systems. For example, a Megaways title may include cascades and a Hold-and-Win-style bonus feature. The paytable remains the final source for understanding the exact combination used.

RTP, Volatility and Hit Frequency

Megaways, Cluster Pays and Hold and Win describe how parts of a slot are structured. They do not determine its RTP or volatility by themselves.

RTP is the theoretical percentage of wagered money that a game is designed to return across a very large number of rounds. It does not predict what one player will receive during a single session. For a more detailed explanation, read what Return to Player actually measures.

Volatility describes how returns are distributed. A high-volatility game may produce less frequent but potentially larger payouts, while a lower-volatility game may produce smaller results more regularly.

Hit frequency estimates how often a spin produces any qualifying win. It does not indicate whether those wins will be greater than the original stake.

If the game includes a feature-buy option, that mode may have a separate cost, RTP or volatility profile. Review the information shown for the feature instead of assuming it behaves like entry through the base game.

Common Misconceptions

“117,649 ways means 117,649 chances to win”

The number describes possible symbol paths across the current reel layout. Those paths are not necessarily equally likely, and the figure is not the probability of receiving a win.

“More ways always means a higher RTP”

The ways system and RTP are separate parts of the game’s mathematical model. A game can offer thousands of ways while having a lower RTP than a traditional payline slot.

“A long cascade makes the next spin more likely to win”

A cascade sequence follows the rules of its current round. It does not make the next independent paid spin more or less likely to produce a winning result.

“A Hold-and-Win counter reset means the game is becoming hot”

The counter resets because that behaviour is part of the feature’s rules. It does not show that the game is preparing to produce a larger prize.

“A playing strategy can change the slot’s RTP”

Betting patterns and previous results cannot change the programmed RTP of an RNG-based slot. A provably fair verification system may help confirm how a particular result was produced, but it does not alter the game’s RTP or influence future outcomes.

What to Check Before Playing

Before using real funds, open the game’s paytable or information panel and confirm:

  • The stated RTP and volatility
  • The maximum possible win
  • Whether the feature-buy mode has separate figures
  • How winning symbols connect
  • The minimum cluster size
  • Whether diagonal connections count
  • How cascades and multipliers behave
  • The Hold-and-Win trigger and number of respins
  • How the counter resets
  • How value, jackpot and collector symbols are resolved
  • What happens when every grid position is filled

Do not rely on the mechanic’s name alone. Games using the same system can have substantially different rules and mathematical profiles.

Key Takeaways

Megaways uses changing reel heights and calculates wins through adjacent-reel ways. Cluster Pays rewards connected groups of symbols on a grid. Hold and Win locks value symbols during a limited respin feature.

Cascades, multipliers, expanding grids, collection meters and jackpots are common additions, but they do not operate identically in every title.

The mechanic explains how the game is structured. It does not reveal the RTP, volatility or likelihood of a particular result. Check the paytable for the exact version being played and choose limits that fit your budget.

Play Responsibly

Slot outcomes are random, and no feature, strategy or previous result guarantees what will happen next. Set a spending limit and time limit before playing, never chase losses and do not gamble with money needed for essential expenses.
