With this game, Scientific Games enters the skill-based slot arena with a skill version of Space Invaders, based on the legendary video arcade shooting game first released in 1978 in Japan and brought to the U.S. by Bally, and as part of the first Atari video-game consoles.
The base game for Space Invaders is a six-reel, 60-line video slot on the Blade s32 cabinet. During the main game, the object is to collect “shots” through special symbols. Collecting 50, 100 or 150 shots gives the player the option to enter the main Space Invaders Bonus.
Alternatively, the player has the option to “buy” 100 shots for 2,000 credits and bypass the reel-spinning game altogether, making it a pure skill game.
The bonus plays out exactly as the arcade game, with players awarded credits for each alien ship shot down, or alternatively, one of the “Jackpot Pools” displayed at the top of the screen. If you hit the mother ship, you advance a level for higher wins.
Each jackpot pool represents the value of all of the invaders in that level, plus the credit value of hitting the UFO in the Space Invaders Bonus. With each spin, the value of random invaders in a level will be increased and the value will be added to the meters. As the player is awarded the various amounts in each level, the amount of the pool will reduce. Once that level is completed, if the value is below the reset amount, the pool will reset. Level 1 resets at 2,665 credits, Level 2 resets at 5,165 credits, and Level 3 resets at 10,165 credits.
The game program has a variable payback percentage, based on skill level of the player, from a minimum 86.73 percent to a potential 96.8 percent with a maximum skill level.
