About this Slot
The Slammer is a crime-themed slot from WhyNot with a 5x5 grid, cluster pays, and an RTP of 96%. The volatility is medium and the maximum win is 20,000x.
Wins form from clusters of connected symbols on the grid. When a winning cluster lands, those symbols drop away and new symbols fall to fill the space, creating cascading reels.
A Mojo meter accumulates points from each winning symbol during base play and tumbles. Once the meter reaches 35 points, it triggers free spins and enters the first bonus stretch. The Mojo meter persists across stretches, carrying forward points and unlocking additional free spins as it accumulates.
An ink mechanic operates during Mojo spins and THE SCORE bonus round. An outline appears on the grid, and each winning cluster lights one cell within that outline. When the entire outline is filled, it converts into a BIG WILD block that can range from 2x2 to 4x4 in size.
Four escalating bonus stretches form the bonus structure. The first stretch applies no multiplier to wins. Each subsequent stretch increases the juice multiplier value, amplifying all prizes. All stretches have unique juice values and ink layouts. If the Mojo meter falls below 35 at the end of a stretch, the bonus ends.
The bonus buy options are JUICE at 3x bet, DOUBLE JUICE at 6x bet, FIRST STRETCH at 100x bet, THE SCORE at 250x bet, SECOND STRETCH at 300x bet and THIRD STRETCH at 500x bet.
