Jackpot King review

Jackpot King fruit machine by Project Coin is a £500 jackpot slot machine found in many amusement arcades. Project Coin slot machine are unique in the fact that they are not random, unlike many other £500 jackpot slot machines. This results in some strange behavior, and causes regular streak like patterns and drawn out periods of tight game play. They were never going to be the most popular slot machine manufacturer with this type of programing, however they have cornered themselves a little niche, especially as their only real competition now is Barcrests range of £500 machines. Many players do not know that they are on a fixed, non-random percentage, although checking the help pages and little black stickers will confirm this. It is good practice to check the help pages on any £500 machine. These will have important information such as the target percentage, and how the features and win lines work. Always avoid arcades with 90% random £500 jackpot machines. Jackpot King fruit machine is slightly different to many other Project Coin slot machines, which often just feature bars, X’s and free spins. This one has many playable features and a progressive cashpot, and as the machine is not random, certain wins become ‘due’ at certain points. So like many £70 jackpot fruit machines, this can make them readable in certain situations.

The cashpot is paid by landing five shields in view. Any less shields in view add cash amounts to the progressive cashpot until it is won. The game uses five paylines, working both forward and back in the standard Project manner. All of the features are scatter pays, and are used anywhere in view. For a Project machine, this has a lot of fun features. The free spins bonus feature is activated by lighting fifteen keys in the matrix. This is a very rare, and low paying feature, however the keys in the matrix can hold over to help with activating the bonus game.

Jackpot King Bonus Features

Goblets Feature
Three or more Goblets awards a fun hi lo feature with the perceived potential of a £500 win. This is an interesting feature, as you can actually lose everything. Generally it will win on the good cards, so keep going until you hit a bad card, then collect.
Fours and nines often win, but tend to block at £25, and may lose at that point.

Book of Spells Feature
Three or more books of spells awards a pick a win feature, with values in the range of £30. Simply select one of the books to be paid the hidden cash prize.

Three men pays a mystery win of around £50.
Four men pays a mystery win of up to £300.
Five men instantly pays the £500 jackpot.

The Tower and Castle features both have the potential to pay the jackpot, but as the machine is not random, neither are the features, so don’t be too disappointed if you think you have selected the wrong tower.


The game is housed in a wide touch screen cabinet, with high definition monitor and clear bright graphics. This makes it enjoyable and approachable to players, with a large selection of features, and fun ways to win big cash prizes.
