Behind Bars: Masterplan Demo Play Free Demo Slot

Slot Overview

Behind Bars: Masterplan is a 6-reel, highly volatile crime-themed online slot by Bullshark Games featuring a Hold & Win bonus round and a maximum win of 12,000x the bet.

Gameplay & Bonus Features

Using a 6-reel, 5-row reel matrix, Behind Bars: Masterplan operates on the scatter pays engine, with wins awarded when 8 or more matching symbols appear anywhere within the playfield. Players can opt in for real-money play with bets ranging from €0.10 up to €75, whilst the game comes with a fair return to player percentage of 96.29%.

Each reel has its own multiplier sitting above it, and these are refreshed on every spin with new random values.

Whenever a reel contributes to a win, its multiplier is applied. If multiple reels are involved, their multiplier values are added together before being used, which can quickly push wins higher across a good cascade.

After each win and tumble, one or two reels are boosted further. This can either increase the multiplier by a fixed amount or multiply it again, allowing values to build up during the same spin. Once the spin ends, everything resets back for the next round.

Escape Plan bonus

Landing 3 scatters triggers the Escape Plan bonus, which shifts the game into a hold-style feature using the same grid.

You start with 3 spins, and every time a new symbol lands, the counter resets back to 3. The feature continues for as long as new symbols keep appearing.

Unlike most hold-style setups, symbols don’t stick. They land, apply their effect, and are removed before the next spin, so the focus is on building multipliers rather than filling the grid.

Reel multipliers carry over and keep increasing throughout the feature, which is where most of the potential comes from.

Instant Win symbols land with fixed values, which are then multiplied by the reel they land on and added to the running total.

Booster symbols increase multipliers instead. Some affect a single reel, while others apply across all reels at once, either adding to the value or multiplying it further.

If a spin lands nothing new, a search party can trigger, dropping extra instant win symbols onto the grid and resetting the spin counter, keeping the feature alive.

The Great Escape bonus

Landing 4 scatters triggers The Great Escape, which uses the same core setup but starts with an advantage.

At the beginning of the feature, three reels are given boosted multiplier values straight away, giving you a stronger base to build from as the bonus progresses.

Theme & Design

The production of Bullshark Games titles continues to improve with each release, as we have seen most recently in Junkyard Kings 2 and Gearlab Genius. The good news for fans of the studio is that we’re being treated to more of the same in Behind Bars: Masterplan, as we join three suspicious-looking inmates in prison who are plotting their escape, with a big win in tow, too.
