Fort Knox is a 5 reel, 20 pay line slot machines that is themed around high security and precious items and there is no surprise that this online slots takes place against the backdrop of a huge safe. The open round door of the safe frames the reels, with the entire background taken over by the huge deposit box. Everything about the slot game is clinical with greys and metallic areas, even the symbols are illuminated by strong security lights that shine down on them from above. There is also an animated gold bar that is complete with moustache and a top bar that watch each move that the player makes as they progress around the slot machine. There is some jazzy music that is an excellent choice for this style of game and the overall design is original and extremely well executed giving players some outstanding surroundings in which to hopefully take home some big wins.
Most of the parameters in Fort Knox can be customised to the players specifics, and they just need to click on the gear icon which can be found in the upper left-hand corner of the game screen to access the settings menu that will appear on the other side of the safe door. There are many plus and minus symbols where players can activate or deactivate the pay lines, whilst also setting the value that they wish to bet per line. It is important for players to remember that the amount they will win is dependent on both the amount of their initial bet and which symbols they align on their active pay lines. Bold players are rewarded; therefore, it is worth taking a risk. On the main screen players will find the Bet Max button and this is there for those who are feeling lucky and wish to go all in on one single spin. Once ready all the player needs to do is click on the red spin button and keep their fingers crossed that the wins come in.
After every successful spin players are given the option to partake in a double or nothing gamble mini game, all they need to do is click the gamble button. Answer correctly and wins are doubled but make a wrong guess and lose all your coins. There is also an Autoplay function which players can select if they want to sit back and watch the action unfold before them, and this can be programmed to play for a certain amount of spins and stopped at any time.
The reel symbols in Fort Knox take on expensive items that you could imagine being found in a safe and include money, diamonds, jewellery, valuable documents, ancient artefacts and so on. There are just five basic symbols however it is their value that makes each one unique. The two other symbols are what make the slot that bit more exciting, with the gold bar symbol being the scatter which will trigger wins no matter where it lands on the reels, and landing three or more of the scatters will bring rewards in the form of free spins and cash, technically this means a risk-free chance to win even more. The stamp symbol is the wild in Fort Knox and this can replace any of the basic symbols to create winning combinations and landing three or more will activate the 2 way pay features for the following 10 spins seeing winning combinations paying from left to right and right to left giving twice as many wins.
