The I.R.I.S 3000 is so unique it is beyond comparison. The top award isn’t the highest available, but the coin values are fixed at 0.50 and three can be placed on the single pay line. The real difference is in the reels: the five you see and the two you don’t.
In this slot, you can choose five out of seven reels to play with. Then you can play with up to three coins on the single pay line. A single coin gives a chance to spin and win, two coins will award you with a laser beam, and play the max bet of three coins to gain another laser.
These two beams scan back and forth above all seven reels and will randomly stop at any one of the open or closed doors. If the beams stop at a closed door, it will be opened by the end of the spin and give you another reel to use.
The aim of this video slot is to open all seven of the doors to trigger a randomly generated multiplier that will increase any winning combinations. If you open all seven doors, reveal the top 10x multiplier, then match five ‘Radiation Hazard’-symbols, the progressive will drop.
