Game Features
Reel Multipliers
There are six multiplier fields, one above each reel. Each spin generates new random values for these fields. Possible values are: 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, and 100x.
If at least one symbol on a reel contributes to a win, that reel’s multiplier is applied to the win. If multiple reels with multipliers greater than 1x contribute to a single winning combination, their values are summed before being applied to the win. After the win is calculated, when symbols are removed, one or two random reels receive a multiplier increase.
- 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 each new spin in the main game. Note: The maximum Reel Multiplier value is [value].
Escape Plan
Three FS Scatter symbols trigger the Bonus Game. This bonus game uses a new mechanism, described below. All Reel Multipliers start at 1x. Reel Multipliers are progressive and do not reset throughout the bonus game. The Bonus Game is a Hold and Win feature on the same grid as the main game.
The game begins with 3 spins. Each time a new non-blank symbol lands, the number of spins resets to 3. If the spins reach zero, the feature ends. All wins are accumulated and displayed in the Total Win field and will be credited at the end of the bonus game. During the spin, all reels rotate. None of the symbols that land remain in place: they perform their action and are removed during the next spin. The following symbols may land during the Bonus Game:
Empty cell
They don’t pay out or have any other effect.
Instant Win Symbol
- Displays a random instant win value.
- Possible values: 0.5x, 0.7x, 1x, 2x, 3x, 4x, 5x, 10x, 15x, 20x, 25x, 50x, 75x, 100x.
- The value is multiplied by the current Multiplier of the reel it lands on and added to the Total Win.
Single Reel Booster
Each symbol increases the multiplier of the reel it lands on.
- Adder symbol
- Possible additive values: 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x.
- Multiplier symbol
- Possible multiplicative values: x2, x3, x4, x5, x6, x7, x8, x9, x10.
All Reels Booster
Each symbol increases the multiplier for all 6 reels.
- Epic Adder symbol
- Possible additive values: 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x.
- Epic Multiplier symbol
- Possible multiplier values: x2, x3, x4, x5, x6, x7, x8, x9, x10.
When multiple special symbols appear on the grid in a single spin, the following sequence occurs:
- Single-reel and All-reel Multipliers are triggered from top to bottom, left to right.
- Instant Win symbols apply their Reel Multipliers, and the values are added to the Total Win field.
Search party
- Triggered randomly if no new symbols appear during a spin.
- In this case, 2, 3, or 4 Instant Win Symbols are added to random empty spaces.
- Instant Win symbols apply their Reel Multipliers, and the values are added to the Total Win field.
- Resets the spin counter to 3.
The Great Escape
4 FS Scatter symbols trigger the Bonus Game. This Bonus Game uses the same mechanism as the ESCAPE PLAN Bonus Game, with the differences described below. Three random reels start with increased multipliers. Possible starting values are: 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x.
Paylines
The winning combination requirements stated in the main game also apply during bonus features or free spins, unless otherwise stated. Each bet covers all winning combinations, unless otherwise stated. All paid symbols are based on Scatter wins, meaning at least eight identical symbols must appear anywhere on the grid to win. After each win, the symbols in the winning combination are removed and new ones appear. This continues until there are no more new wins remaining on the reels.
Reel Multipliers appear above the reels and play a key role throughout the game, adding an extra layer to every win and evolving as cascades continue. As symbols disappear and new ones appear on the grid, the layout changes rapidly, creating different results from spin to spin.
Trigger the Bonus Game to enter Hold and Win mode, which focuses on collecting Instant Win Symbols, while Reel Multipliers continue to accumulate throughout the round. Each symbol landing feels like another step toward escape.
With a distinct theme, action-packed gameplay, and a maximum win of up to 12,000x the bet, “Behind Bars: Masterplan” delivers a tense experience where timing, planning, and gradual progression are key.
