Slot Details

The slot plays out on 5 reels and 3 rows, and players can choose any of the 20 fixed paylines to make winning combinations. A 6th reel appears during the heist mode, but it does not display any extra symbols. The developer, iSoftBet, rates the RTP at 7.5 out of 10, with an RTP of 96%. Both average and high rollers can walk away with decent prizes due to the slot’s high volatility paired with the RTP rating. You can also expect frequent wins as the slot has an estimated hit frequency of 26.5%. 

How To Play

There are plenty of betting options, ranging from $0.2 per spin for those who prefer a low stake to $200 for high rollers. Each player has been accommodated by the variety of betting options in the betting range. To create winning combos, match 3 or more similar symbols starting from the left of any adjacent reels. 

For lower paying symbols, A, 10, J, Q, and K, match at least 3 symbols to walk away with x0.75-x2 of your stake. High-paying symbols include money, a watch, gold bars, a bag of diamonds, and the robber. These symbols hold a reward of 3x to 25x your bet. The wild has no value of its own, but it can substitute any of the other symbols on the reel to create more winning combos. The only symbols wilds cannot replace are the diamond, scatter, and detonator. 

Theme, Graphics, & Music

The slot features a robbery theme where the player joins forces with the master thief to rob a bank. In the background is a dark surrounding except for the frequent surveillance lights. Various bright and wacky symbols land on the reel during the spins, which is characteristic of blue gaming. 

The music playing in the background is calm yet mysterious, leaving players on the edge of their seats. The sound effects also add to the excitement of the game with the frequent cashing of money and alarm sounds. 

The robber’s disappointment and excitement can be heard every time you make a move, and it fits perfectly with the theme. The developer has nailed it when it comes to music and graphics. 

Special Features

Random Modifiers

At least 1 of the 3 modifiers will be randomly triggered in the base game. They include:

  • Multiplier win. A random win multiplier that boosts the next win x2, x5, or x10. 
  • Wild added. Adds 3 to 6 wilds to the reels randomly. 
  • Mystery. Awards 5 to 10 mystery symbols that transform into random matching symbols.

Free Spins

When you land 3 or more scatters you get to experience this feature. The number of spins you get depends on the number of scatters you match; 3 scatters earn you 8 free spins while 5 scatters earn 12 spins. You can also win multipliers of x1 to increase each spin by 1.

Heist Mode

You need at least 3 detonator symbols to activate 20 heist spins. Diamonds are added to the reels during this feature, and matching 5 or more triggers the respin feature. Failure to initiate the diamond heist respins automatically means the heist is over and the regular play resumes, and all remaining spins are lost. 

Bonus Respins

The respins feature is activated by matching 5 or more diamonds during the heist mode. The diamonds become sticky while the rest of the spaces are cleared. If additional diamonds land in these empty spaces, the respins rest to 3, and you can continue playing until you run out of respins. 


Special diamonds are also present during this feature, and landing one unlocks the adjacent vaults and resets the respins. If an alarm symbol lands on the reels, the position is blocked and the respins end. 

There are diamonds with particular value attached to them, including; 

  • Mega diamond carries an award of 500x the stake
  • Major diamond rewards 200x the bet.
  • Mini- awards 100x the stake.
