Starburst Galaxy Slot Features

Feature Generator, Galaxy Star, Mega Star, Elevate Feature and the Multiplier Collect Meter shape the slot’s core action, while Wild symbols and the bonus buy menu add more control over how each round develops.

Wild Symbols

Any win starts an Avalanche: the winning symbols disappear and the remaining symbols move down to fill the empty positions, until there are no more wins. When a winning combination without a Wild disappears, a Wild symbol is placed at the centre of that combination. Wild symbols substitute for all symbols except the Scatter.

Feature Generator

Each winning combination adds progress to the Feature Generator. After every 5 win combinations won in a row, the game awards one feature at random from five options; when no wins remain, awarded features activate one by one until there is a new win.

• Destroy: removes one or more random types of symbols from the reels.
• Random Wilds: replaces from 3 to 9 payout symbols with Wild symbols.
• Expanding Wilds: turns all Wild symbols into 3 stacked Wild symbols.
• Line Transform: fills a row or a reel with a random payout symbol.
• Upgrade: upgrades one or more symbols to a higher-paying type.

Galaxy Star Feature

The Galaxy Star feature starts when the fifth Feature Generator award lands. The play area expands to 7 reels and 7 rows, and a 3×3 Wild symbol appears on positions without Scatter symbols. After wins are evaluated, the game removes win symbols and adds from 4 to 8 regular Wild symbols.

Galaxy Meter

The Galaxy Meter activates when the 3×3 Wild symbol appears. Every winning combination adds to the meter, and reaching 50 awards the Galaxy Star feature again. Once it fills, the meter starts again from the beginning and the remaining winning combinations count towards the next cycle. The progress of the Feature Generator and the Galaxy Meter resets to 0 at the start of each new spin.

Mega Star Feature

Every 3 Scatter symbols appearing during the same spin award Mega Star. After the Avalanche ends and no wins remain, the feature activates and places a 2×2 Wild symbol on the reels. During the next Avalanche, the game removes win symbols and adds 2 to 5 regular Wild symbols.

Multiplier Collect Meter

When Mega Star activates, one or more Scatter symbols may carry multipliers. The available values are x2, x3, x5, x10 and x25. These values feed the Multiplier Collect Meter, and it applies all collected multipliers to winning combinations until the game round ends.

Elevate Feature

The Elevate Feature lets you activate one of five options before a spin and keep it active until you turn it off. Depending on the option, it increases the chance of reaching Galaxy Star, activates a feature, or starts Galaxy Star with awarded features and a random multiplier.

• Bonus Boost: x3 the bet per spin. Increases the chance of reaching Galaxy Star.
• Mega Star: x10 the bet per spin. One free main game spin is guaranteed to have 3 Scatters, which activate Mega Star.
• Boosted Mega Star: x50 the bet per spin. One free main game spin is guaranteed to have 3 Scatters, at least 2 of them with multipliers, activating Mega Star and the Multiplier Collect Meter.
• Galaxy Star: x100 the bet per spin. Guarantees Galaxy Star feature access.
• Galaxy Star Bonanza: x500 the bet per spin. Starts Galaxy Star with 5 awarded features in the Feature Generator and a random multiplier from x2 to x75.

Starburst Galaxy Slot Review

Starburst Galaxy leans into a deep-space look with glowing gems, purple nebula effects and a glossy arcade layout. The identity comes from the cosmic grid, the neon title treatment and the way the symbols float over the background rather than sitting in a standard frame. It looks polished without losing clarity.

The main draw is the Feature Generator, which builds from winning combinations into extra features after 5 wins in a row. That structure gives the game real progression, and the Galaxy Star expansion to 7 reels and 7 rows adds more than a cosmetic change. Each 3 Scatters in the same spin also award Mega Star, whose Scatter multipliers feed a meter that applies to all wins until the end of the round.

Everything builds from winning combinations within a single round, since the Feature Generator and the Galaxy Meter reset with each new spin. The Elevate menu sells direct access, from Mega Star at x10 the bet per spin to Galaxy Star Bonanza at x500 the bet per spin, and the RTP stays at 96.00% whichever option is used.
