Reels O Dublin - HD Slot Machine for iPhone/iPad game reviews & Metacritic score: Test your luck against the Luck of the Irish! This 5 reel mechanical slot from WMS Gaming is one of the best Hot Hot Super Jackpot titles we’ve ever seen. This is low by today’s standard – where 50 and 100 are common – though for an electromechanical game this would have been a large number of win-lines when it was first released. This slot is based on the most common 5 reel by 3 row grid pattern.
