You then enter the 'Tile Matching' part of the bonus where you are given 5 Mah-Jong tiles and if they match any of the tiles on the screen, you will be awarded an increased multiplier for your free spins, a credit award, or additional free spins. The primary bonus is triggered by landing either 2 or 3 scattered bonus symbols for 5 or 8 spins respectively.
The game also offers 3 'Bet Levels' and to qualify for certain features, such as the primary bonus, you need to be at 'Bet Level 3'. If you do, you'll win a progressive but you don't win the associated 27 line wins though, too bad! First of all, it's a line-based game(27 lines for the version I play in this slot video) which offers 'Blackout Pays' which are progressives that are awarded if you fill the screen with stacked 7s with the Red Sevens being the most valuable. I have to say I'm going to give this one another shot! This slot actually has a lot going on for one that's primarily a mechanical reel slot machine.
The Slingo Mah-Jong slot machine by IGT is a hidden gem!
