Planet X Slot Review

The Planet X slots game was produced by the OpenBet slots design company and is leased out by casinos using many different primary casino platforms. As a standard OpenBet do not include the house edge information of their slots games, however some casino do list this information in the game help files. It is not clear whether their games are configurable and as such you should treat the information in this review as a guideline only when playing at a casino that does not explicitly state the house edge they use.

These visitors certainly aren’t friendly.

This game is a 5 reel game, with 20 paylines and you can only bet one coin on each payline.

The ‘Wild’ symbol is wild.

There are four bonus features when playing Planet X. The first two bonus features are activated when you receive 3 or more of the ‘Mystery Man’ symbol anywhere on the reels. When this happens you will be randomly awarded one of two bonus features. The first awards between 15-60 complimentary spins. During the complimentary spins, you can receive ‘Super Wild’ symbols. These symbols remain locked in place for the number of spins listed on the symbol. The second bonus feature takes you to a new screen showing a farmer a series of items and a spaceship. Direct the spaceship to the item you want it to destroy and receive a prize for each item destroyed. When the spaceship destroys the farmer the bonus feature ends.

The second two bonus feature is activated when you receive 3 or more of the ‘Robot’ symbol anywhere on the reels. When this happens you will be asked to choose between the Alien Square and Metal Madness bonus features. If you choose the Alien Square bonus feature you will be taken to a new screen showing a 9 square grid. You have to pick squares at random one at a time. The objective is to reveal three ‘O’s in a straight line. If you reveal 6 or more ‘X’s you lose everything you have won in the bonus feature so far. If you win the round you are given the choice to play another round or collect your winnings. If you choose to play on, remember you are risking your winnings from all previous rounds and all ‘X’s revealed in previous rounds still count towards the new round. If you choose the Metal Madness bonus feature you will be taken to a new screen showing a giant robot destroying a city. As it stamps down the street you will receive a prize for every object it crushes. If it crushes a nuclear weapon the defcon status rises. Some objects may reduce the remaining time. When the time runs down to zero you are awarded all the prizes won in that round and given the choice of whether to allow the robot to continue for another round or collect your winnings. If you choose to let the robot continue, remember that if the defcon meter reaches the top you lose all your winnings and that all previous nuclear weapons crushed still count in the new round.


Certainly very entertaining and with a forgivable house edge given the scope of the game, Planet X deserves a top notch score.
