Symbols

The high-paying symbols are cash, a scheming banker, a wealthy lady clutching her jewels, essential heist equipment, and a newspaper. Five cash symbols on a payline will earn you 150x your stake. Five of each of the other high-paying symbols will earn you 75x your stake. The wild prisoner symbol substitutes for all symbols except the dynamite scatter and shows up on all reels except the leftmost one.

Casino bonuses, such as a welcome bonus, allow you to play the slot without using your own funds, and you can find out more about the various symbols and their worth.

Hold and Win bonus game

This is where the real action begins, and it takes an unconventional approach. Rather than free spins, the respins take center stage in the game.

Landing three or more dynamite symbols anywhere in view launches the Respins feature. You get three respins, but each additional explosive will reset the tally.

You will blow up the tiles of the ground and slowly lower the safes and jewels. For each exploded tile, you get a small prize, but you will only win some real loot by lowering items to the bottom so the prisoner henchman can drag them away.

Cash prizes and jackpots

Various safes contain cash prizes, and the diamond safe may have one of four jackpot prizes. The largest jackpot will win you 1,000x your stake. After a safe is taken out, the line is covered with earth again. You can take out up to three safes from each line, after which you can place no more explosives on the line.

The round ends when the spin counter is at zero or the maximum number of safes is collected. Your prizes are added together and paid out, which means you can make quick money when playing this slot.
