Doctor Dust

ABOUT THE GAME

Step into the wasteland and help the Doctor scavenge for survival.

"Doctor Dust" is a 5x5 cascading cluster game set in a post-apocalyptic wasteland, where wins are formed by 4 or more matching symbols. A mysterious plague doctor scours the ruins, collecting components that unlock powerful Grid Boosters, each one reshaping the grid in its own way.

Trigger the bonus game for an open-ended run of spins, where every spin comes with at least one Grid Booster and the feature continues as long as at least 8 winning symbols are collected during a spin.

With its bleak wasteland theme, deeply interactive Grid Boosters, and a max win potential of 12,000 times your bet, "Doctor Dust" delivers a rich experience across all modes.

The max win can be achieved in all game modes.

Collect the components and master the ruins.

FEATURES

COLLECTING WINNING SYMBOLS

All winning symbols are counted during the spin.

There is a collection bar next to the grid with 5 segments. Fill each segment of 8 symbols to unlock a random Grid Booster:

Fill 1 segment to get the 1st Grid Booster.

Fill 2 segments to get the 2nd Grid Booster.

Fill 3 segments to get the 3rd Grid Booster.

Fill 4 segments to get the 4th Grid Booster.

The Grid Boosters are awarded in random order, with each Grid Boosters awarded only once per spin.

When 5 segments are filled (40 symbols collected) in a single spin, the bonus game is triggered.

Collecting continues beyond 40 symbols. Every additional 8 symbols adds +1 to the number in the middle of the bar, up to a maximum of 4. This number indicates how many bar segments will be pre-filled at the start of the bonus game. After having 4 in the middle, no more symbols are collected.

The symbol collection resets with each new spin in the base game.

GRID BOOSTERS

Four different Grid Boosters can be unlocked by collecting winning symbols.

All Grid Boosters trigger one by one once the grid settles, with the grid cascading and settling again after each inpidual Grid Booster trigger.

CLONE

Clones one random row to 1 or 2 adjacent rows.

Wild symbols on the overwritten rows are not replaced, they remain in place.

Cell multipliers on the cloned row are also copied to the destination row. If the destination already has multipliers, the values are added together.

SWITCH

Randomly selects 1–3 rows and transforms every symbol in those rows to match the first symbol of each respective row.

Wild symbols in the rows remain as Wild symbols.

Cell multipliers stay attached to their cells, only the symbols change.

WILDS

Adds 2-5 Wild symbols to random positions on the grid.

Wild symbols may be regular Wild symbols or carry multipliers.

Possible values: 2x, 3x, 4x, 5x, 10x, 15x, 20x, 25x, 50x, 100x.

Multipliers on Wild symbols are applied as Cell Multipliers to the grid positions where they land.

If a Wild with a multiplier lands on a cell that already has a multiplier, the values are added together.

POWER LINE

Removes all symbols from one random row and one random column, then fills the emptied cells with new random symbols (no Wild symbols).

Wild symbols in the affected row or column remain in place and are not removed.

Every cell in the row and column receives a random multiplier.

Possible values: 2x, 3x, 4x, 5x, 10x, 15x, 20x, 25x, 50x, 100x.

The cell at the intersection of the row and column receives two new multiplier values, which are added together.

If a cell already has a multiplier, the new value is added to the existing one.

CELL MULTIPLIERS

Cell multipliers are attached to inpidual cells on the grid.

Cell multipliers are only added by the Power Line Grid Boosters and Wild symbols with multipliers.

When a cell with a multiplier is part of a win, the multiplier is applied to that win.

When several cells with multipliers are part of the same win, all their values are added together and then applied to the win.

Multipliers are removed immediately after being applied to wins, at the same time as the winning symbols.

When a cell with a multiplier is cloned, the multiplier is also copied to the destination cell.

WILD SYMBOL

Wild symbols are only added by the Wilds Grid Booster and cannot land during spins.

Substitutes for all symbols in the paytable.

SURFACE SEARCH

Triggered by collecting at least 40 winning symbols in the base game.

At least one spin guaranteed with all 4 Grid Boosters.

This bonus keeps the base game’s mechanics with below described differences.

The bonus game always begins with a spin that includes all 4 Grid Boosters, activated one by one in random order after the grid settles.

During the bonus game, a collection bar tracks winning symbols across 4 segments of 8 symbols each. The number of Grid Boosters for the next spin depends on how many symbols were collected in the previous spin. Each filled sector awards 1 Grid Booster for the next spin.

When at least 1 segment is filled during a spin, another Free Spin is awarded. When no segments are filled, the feature ends. There is no limit to the number of retriggered spins.

From the second spin onwards, symbol counting always starts from 0.

TOXIC VAULT

Triggered by collecting at least 72 winning symbols in the base game.

This bonus game uses the same mechanic as the SURFACE SEARCH bonus game with below described differences.

The number in the middle is 4, meaning the second Free Spin is guaranteed with all 4 Grid Boosters.

Awards 2 Free Spins
