Expanding Grid on slot machines in Morocco: how it works
The expanding grid refers to a mechanic where the base playing surface, usually 5 columns by 3 rows, temporarily widens during a round to offer more winning positions. The enlargement is not permanent: it triggers under certain conditions, lasts for a limited number of spins, then the grid returns to its original size.
This feature changes the way a slot machine round plays out, since the player is no longer betting on a fixed grid but on a format that can grow before their eyes. On an MAD account opened at 1xBet, Melbet, Linebet or Megapari, this mechanic is often paired with other features such as Hold and Win or multipliers.
A mechanism that transforms the base grid during the round
In practice, the expanding grid adds one or more rows to the starting grid once a trigger is reached, often the appearance of special symbols that stay locked in place on the grid. Each locked symbol can push the format from 5×3 to 5×4, which multiplies the number of active positions and therefore the number of possible combinations on each additional spin.
The player doesn’t directly control the expansion; they watch the grid fill up as symbols lock into place. This progression is generally capped at a number of respins set by the game, which limits how long the expanded phase lasts.
A direct effect on the pace of wins and on the risk taken
An enlarged grid multiplies the positions where a paying symbol can land, which increases the frequency of winning combinations during the active phase. On Volcano Millions, this expansion is combined with a maximum win announced at 20,000 times the stake and medium volatility, meaning more pronounced swings in results than on a fixed grid, without changing the overall consistency of spins.
The 96% RTP displayed by this game is still calculated over the full set of spins, expanded phase included, and guarantees no result over a short session. Playing with an MAD account at 1xBet, Melbet, Linebet or Megapari doesn’t change this, as the grid mechanic is identical no matter which operator hosts the game.
The variant used by Volcano Millions
Volcano Millions, released by Winspinity in 2026, applies the expanding grid in an erupting volcano setting. Its base 5×3 grid switches to 5×4 when Hold and Win symbols lock in place, which unlocks fixed jackpots and multipliers that stack on occupied positions.
This combination of features places the game among the evolving-grid slot machines available with an MAD account at 1xBet, Melbet, Linebet and Megapari.

Frequently asked questions
Is the expanding grid reliable on slot machines?
How it works relies on a fixed return-to-player rate, published by the studio that develops the game. Volcano Millions advertises a 96% RTP, calculated over the full set of spins, including expanded grid phases. This figure doesn’t change depending on the operator offering the game.
How can you spot a slot machine with an expanding grid before playing?
The game’s info sheet usually shows a starting format and a maximum format, such as 5×3 expandable to 5×4 for Volcano Millions. The joint presence of a Hold and Win feature or symbols that lock into place is another sign that the grid can expand during play.

1xBet, Melbet, Linebet and Megapari offer this type of game with an account opened directly in MAD. Volcano Millions, with its expanding grid and maximum win of 20,000 times the stake, is accessible under the same conditions at each of these operators.
