Behind Bars: Masterplan

Plan the Escape in “Behind Bars: Masterplan”!

Behind Bars: Masterplan is a 6×5 cascading all-scatter game set inside a high-security prison, where every move is part of a carefully timed escape. Wins are formed by matching 8 or more identical symbols, and each cascade reshapes the grid as new symbols drop into place.

Reel Multipliers appear above the reels and play a key role throughout the game, adding an extra layer to each win and evolving as cascades continue. As symbols clear and new ones fall into place, the layout can change quickly, creating different outcomes from spin to spin.

Trigger the Bonus Game to enter a Hold & Win–style feature focused on collecting instant win symbols while Reel Multipliers continue to build during the round. Each drop feels like another step in the escape plan.

With its strong theme, feature-driven gameplay, and a maximum win potential of 12 000 times your bet, Behind Bars: Masterplan delivers a suspense-filled experience where timing, planning, and progression take center stage.

The max win is available in all bonus game modes and in Surprise Inspection Feature Spins.

Features

REEL MULTIPLIERS

There are 6 multiplier fields, one above each reel.

On every spin, new random values are drawn for these fields.

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

If at least one symbol on a reel participates in a win, that reel’s multiplier is applied to the win.

If multiple reels with multipliers higher than 1x participate in the same win, their values are summed up before being applied to the win.

After win calculation when the symbols are removed, 1 or 2 random reels receive a multiplier boost.

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

Possible multiplicative values: x2, x3, x4, x5, x6, x7, x8, x9, x10

Reel Multipliers are progressive during cascades but reset at the start of a new spin in the base game.

Note: The maximum reel multiplier value is 24 000x

ESCAPE PLAN

3 FS Scatter symbols trigger the Bonus game.

NB! FS Scatter symbol can only land in the base game and not in the bonus game.

This Bonus game uses a new mechanic described below.

All Reel Multipliers start from 1x.

Reel Multipliers are progressive and do not reset for the duration of the bonus.

The Bonus game is a Hold and Win feature played on the same grid as the base game.

The game starts with 3 spins. Each time a new non-blank symbol lands, the spins reset to 3. If the spins reach zero, the feature ends.

All wins are collected in the Total Win field and multiplied by the bet amount to determine the final awarded win.

During the spin all the cells spin.

None of the symbols that land are sticky, they perform their action and are removed on the next spin.

Following symbols can land during the Bonus game:

Blank cell
