Review of Behind Bars: Masterplan Slot Online

4.0 /5

I am more inclined towards history and mythology-themed slots, so when a prison-themed slot dropped, I wasn’t very excited. I couldn’t have been more wrong. This Bullshark Games title kept me engaged for a good couple of hours. It is definitely one of my favorite releases from the studio. Here are my two cents on this game. Before you jump in, read my review thoroughly.

Graphics, Sounds and Animations

4.0 /5

Prison slots aren’t something we see every week, and Bullshark Games uses that to its advantage. The moment the prison courtyard and the reel frame appear, the game looks more like a compact video game scene than a plain slot screen. The background of Behind Bars: Masterplan is a warm, amber-toned prison with cells, long benches, and a vintage wall clock very similar to those seen in Hollywood movies and series. Nobody is late for anything here because they are moving according to the masterplan, but somehow the clock still makes you stressed. The overall color tone is mustard yellow, which is surprising, since prison-break-themed online casino games today typically use blue or blackish blue.

The six-reel multiplier counters sit on top, each starting at 1x and with its own display panel. The symbols remain aligned with the overall theme. The provider has chosen guard ID cards, a baton, toilet paper, soap with string, and classic card suite symbols A, K, Q, and J as symbols for this slot.

The three prisoners present alongside the game grid: the Mastermind, the Toolman, and Muscle, help sell the whole idea. Muscle looks like he could bend the bars without asking you to raise your stake! The toolman has a ‘this plan better work’ face, while the mastermind, the brainy one, looks very nervous. It gives the game a funny, video-game-style personality without making the screen look messy.

The graphics are clean and cinematic. Bullshark Games could easily turn this into a small video game or animated movie. The game falls short in one area: the yellow-heavy background may feel a bit boring, especially during longer sessions. But the game doesn’t look cluttered even on smaller screen sizes. If you prefer gaming on the go, our selection of best mobile casinos includes operators where you can try Behind Bars: Masterplan on compatible mobile devices.

Audio of Behind Bars: Masterplan is all about what you don’t hear. No sirens, no prison guards running and barking orders, just a simple, cold, calculating audio-score that sits in the back while you play. It’s got that conspiratorial edge, like a message on soap being passed in the yard. While the provider could have used some prison-like sounds to flesh out the world (clinking bars or distant footsteps), Bullshark Games chose to deviate from the ordinary. The studio creates this eerie sense of complicity, making you feel like you’re part of the breakout. Simple and effective.

Nothing in this prison remains still, as it should. The animation increases the overall tension of this Bullshark Games slot. The three inmates aren’t frozen with fear; they show subtle gestures. The nerdy prisoner, the one behind the master plan for this prison break, looks nervous and constantly checks his plan; the Muscle and the Toolman keep an eye out. These small movements add a layer of reality to the slot. The cascading reels animations are satisfying. The creator has definitely kept mobile gamers in mind. Spinning the reels on mobile feels no different than on desktop, which isn’t something every studio gets right.

Features

4.0 /5

Is Behind Bars: Masterplan all show in the base game and nothing much in the bonus rounds? Let’s take a look at the in-game features of this Bullshark Games release.

Reel Multipliers

There are 6 multiplier fields in the base game, one at the top of each reel. During every spin, new random values appear on these fields. The possible multiplier values are: 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x.

If at least one symbol on a reel is a part of the win, that reel’s multiplier is applied to the win. If more than one reel with a multiplier value higher than 1x is part of the win, the values of the multipliers are summed up and applied to the win. After wins are rewarded, symbols are removed, and 1 or 2 reels get a random multiplier boost.

Possible additive values: 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x.

Possible multiplicative values: 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x.

Reel multipliers are progressive during cascades but reset at the start of a new spin in the base game. The maximum reel multiplier value is 24,000x.

Escape Plan

3 FS scatter symbols activate the bonus game, aka Escape Plan. The bonus game utilizes a new mechanic. All reel multipliers are progressive, do not reset during the bonus, and start at 1x.

The bonus game starts with 3 spins and is a Hold and Win feature played on the same grid as the base game. Every time a new non-blank symbol appears on the grid, the spin counter resets to 3. If the spins number reaches 0, the bonus round ends.

During the spin in this bonus round, all the cells spin. None of the symbols that appear on the grid are sticky; they perform their action and are removed on the next spin.

Special symbols that appear in the bonus game:

  • Blank Cell: These symbols do not pay out and have no other effect.
  • Instant Win Symbol: This symbol reveals a random instant win value. The possible values are: 0.5x, 0.7x, 1x, 2x, 3x, 4x, 5x, 10x, 15x, 20x, 50x, 75x, 100x. The symbol value is multiplied by the current Reel multiplier of the reel it landed on and added to the total win.
  • Single Reel Booster: The added symbol is the Single Reel booster. It increases the multiplier of the reel on which it appears. Possible additive values are: 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x.
  • Multiplier Symbol: Possible multiplicative values are: 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x.
  • All Reels Booster: This symbol increases the multiplier values of all the 6 reels.
  • Epic Adder Symbol: Possible additive values are: 1x, 2x, 3x, 4x, 5x, 6x, 7x 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x.
  • Epic Multiplier Symbol: Possible values are: 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x.
  • Search Party: This is randomly triggered if a spin results in no new symbols. When this symbol appears, 2, 3, or 4 Instant Win symbols are added to random empty cells. Instant Win symbols apply their Reel multipliers, and the values are added to the total win field. This symbol resets the spin meter to 3.

If there are multiple special symbols on the grid during a spin, the order of actions is as follows:

  • Single Reel Boosters and All Reels Boosters act from top to bottom, left to right.
  • Instant Win symbols apply their Reel Multipliers, and the values are added to the total win field.

The Great Escape

4 FS scatter symbols trigger this bonus game. The mechanics are almost the same as the Escape Plan bonus game. The small differences are listed below:

  • 3 random reels start with increased multiplier values. Possible multiplier values are:
    2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x.

Bonus Buy

You can buy the bonus game or increase your chances of triggering the bonus game for a price. The game’s volatility changes to high when you choose to buy the bonus games. Here are the details on buying a bonus at a €1 bet.

  • Bonushunt Feature spins: 3x the base bet, each spin is 5 times more likely to trigger the bonus game
  • Surprise Inspection Feature spins: 50x the base bet; all reels have a random multiplier value of 2x or higher. At least one win is guaranteed.
  • Escape Plan: 100x the base bet.
  • The Great Escape: 250x

During my session in the demo game, I purchased The Great Escape and won €47, which is considerably less than the amount of money I spent. But I had an amazing experience.

Our Verdict

Behind Bars: Masterplan is a clever blend of themes and mechanics. Multipliers build like a plan coming together. Cascades drop like pieces falling into place. The RTP of 96.29% is in line with the market average, and the medium volatility provides balanced gameplay. The most attractive part of the statistics is the 12,000x maximum win. I think the free demo is worth trying first to understand how the multiplier system develops before moving to real-money play.
