Fill beakers with cash values in a lab where every completed horizontal row clears instantly and pays out its sum. Your task is to land 6 or more beakers anywhere on the 5×4 grid: that triggers the Hold & Win bonus, locking every beaker in place for 3 respins. Clear a full row during the bonus and the respin counter resets to 3, while special ALL, CROSS and EXTRA beakers collect, absorb and multiply the values stacked around them. Mad Scientist: Breaking Beakers - Hold and Win is a high volatility, fixed paylines slot from Betsoft. It uses a 5x4 grid where winning combinations clear horizontal lines, causing symbols to drop down. Landing 6 or more Beaker symbols triggers the Hold & Win feature, which includes special Beakers that collect, absorb, or boost values. Here is how you play.
Pick a stake and spin the 5x4 grid.
Watch for matching symbols on adjacent reels from the leftmost reel.
When a horizontal line clears, its value is awarded and new symbols drop into place.
Land 6 or more Beaker symbols anywhere to start the Hold & Win feature with 3 respins.
During Hold & Win, new Beakers reset respins to 3 when they contribute to a cleared horizontal line.
Special ALL, CROSS, and EXTRA Beakers modify values before the round ends.
Hold & Win Feature: Triggered by 6 or more Beaker symbols, it awards 3 respins on a cleared grid where only Beakers and jackpot Beakers appear, with respins resetting to 3 when a horizontal line is cleared.

CROSS BEAKER: This modifier absorbs values from its row and column in the Hold & Win Feature.

During these respins, new Beakers that land drop to the lowest available position. Clearing a horizontal line of Beakers awards their values and resets the respin counter to 3.
