Meridian Glass Slot Demo by Catville Games

Meridian Glass by Catville Games Slot Overview

Meridian Glass by Catville Games pairs starry skies, rooftop telescopes and a colourful coastal skyline with glossy astronomy symbols. Its tumbling clusters share a mechanic with Golden Boy, but here an observatory-themed Star Meter upgrades wilds during free spins.

The Star Meter turns arriving wilds into bonus progression, unlocking sticky positions before switching wild multipliers from addition to multiplication. Total Eclipse adds double meter points and an extra sticky slot at the final step. Explore these mechanics in the free demo on BonusTiime.

Meridian Glass Slot Features

Meridian Glass stacks Cluster Pays, Wild + Multiplier, The Star Meter, Free Spins and Bonus Buy into a layered system where wins can tumble, wilds can upgrade, and bonus rounds can shift from additive to multiplicative growth.

Wild + Multiplier

The Wild symbol substitutes for every paying symbol except Bonus, and it always carries a multiplier. In the base game, wilds land with x2 to x3, then add together inside a cluster. At Step 3, they multiply each other, which makes cluster wins much stronger.

A wild also counts towards cluster size, but the cluster still needs one matching symbol of its own. If one wild touches two clusters, it helps both. Wilds can land on the first drop and during tumbles.

The Star Meter

During free spins, every wild fills the Star Meter, and each step upgrades the round. First Transit reaches Step 1 at 4 wilds, Step 2 at 9 wilds and Step 3 at 18 wilds. Total Eclipse uses 6, 16 and 30 points instead, because each wild counts double.

The upgrades matter because they change how wilds behave. Step 1 gives wilds x3 to x5, Step 2 gives x5 to x7 and makes them sticky, and Step 3 raises them to x5 to x10. Reaching a step also upgrades every wild already on the board, each one keeping the higher of its own multiplier and the new one. Sticky wilds stay frozen on their cell, and Step 3 changes cluster multipliers from adding to multiplying. At most 2 wilds are sticky at once, 3 from Step 3 in Total Eclipse, and the highest multipliers are frozen first. The meter and the sticky wilds reset when the free spins end.

Free Spins

Free Spins trigger when 3 or more Bonus symbols remain on the board after tumbles stop. First Transit awards 10, 12 or 14 spins, while Total Eclipse guarantees 12 to 14 spins. There are no retriggers, so the round keeps its original length.

During the bonus, every wild that lands fills the Star Meter and upgrades the round for the rest of the feature. In Total Eclipse, every wild counts double towards the meter, and reaching Step 3 unlocks a third sticky wild slot. The round always plays at the bet that started it.

Bonus Buy

Bonus Buy holds two direct buys and two watch modes, each watch mode paid again at every spin. The direct buys ask for a confirmation first, and the round paid for is the round played. A watch mode stays on until it is switched off, and its wins are paid on the base bet.

• First Transit: x100 the bet; buys 10 to 14 free spins.
• Total Eclipse: x300 the bet; buys 12 to 14 free spins.
• Transit Watch: x3 the bet per spin; increases First Transit frequency.
• Eclipse Watch: x6 the bet per spin; every trigger opens Total Eclipse.

Meridian Glass Slot Review

Meridian Glass builds its identity from a bright observatory setting, with telescope imagery, a coastal skyline and glossy astronomy symbols shaping the board. The cluster layout and star meter theme work together well, so the design feels tied to the mechanics rather than pasted on as decoration.

The best part is the layered progression inside Free Spins, where wilds charge the Star Meter and eventually turn sticky, then start multiplying each other at Step 3. That gives the game real mechanical movement. High volatility and a 10,000x ceiling also suit the bonus structure, although the base game stays strict.

Meridian Glass develops its bonus progression through the Star Meter, with bonus rounds also available through direct purchases. The Bonus Buy options add choice, but they also show how much the game leans on its bonus cycle.
