The Slingo game was created by New Jersey real estate developer, Dave Lyons and Sal Falciglia in 1994, who also founded the company Slingo, Inc. to create and market games based on the game theme.
It is an online single and multi-player game that combines elements of slots and bingo.
In July 2013 the company was sold to RealNetworks for $15.6 million and two years later, RealNetworks announced that it would sell it to London-based gaming company Gaming Realms.
The game became popular in the UK online gambling industry, with many sites now hosting the game, including its various iterations of which there are currently 12.
These are known collectively and individually as ‘Slingo Originals’ and were developed by Gaming Realms’ development and publishing branch of the same name. Both the games and brand have enjoyed commercial success, and have been praised for their playability and originality.
During the game, other special items may show up in the number spots below the card. Jokers are wild, and can be used to mark off any number in the column in which it appears. A joker in the center (N) column may sometimes become a Super Joker, which can be placed anywhere on the board. (When it appears, the Super Joker must be played first, before any other numbers.)
Devils also occasionally appear during the course of the game. If a devil appears in place of a number, the player’s score is cut in half. Frequently though, a cherub appears and cancels the devil’s effects by shooting it with an arrow.
Other special items include coins, which grant automatic points to the player, and Free Spins. The last four spins of the game (17, 18, 19, and 20) must be bought using points. A player may use accumulated free spins in place of the fee for any of the spins.
Time limits are imposed on spins as well. If a player does not begin his spin within a time limit, he loses that spin. If a player does not mark off all possible numbers or jokers within the time limit, those are considered lost. At the end of the game, the winner is the player who has the most points.
