Double Lucky Line Slot Review

Released January 2020

The Double Lucky Line slot game can be found at Microgaming casinos. Microgaming as a standard now publish the house edge information of all their slots at any online casino that holds a UKGC license (this is a requirement for all UKGC licensed casinos). As such we can say that the House Edge of Double Lucky Line is 3.98%. When playing at any venue that does not hold a UKGC license and does not specifically publish the Return to Player information for their game, this information should be used as a guideline only as we cannot confirm whether or not this game is configurable.


Double Lucky Line has an Asian theme, most likely a Chinese one, given the inclusion of Dragons as symbols. The slot has plenty of the thematic markers you might associate with a Chinese game, from the music that plays in the background to the gold coins that surround the reels.

Double Lucky Line is a 5 reel game that is 3 symbols high. The game uses traditional paylines, with 17 in total playing from left to right.

Middle Row – All symbols that appear on the 5 spaces available on the middle row are classes as Double symbols, and as such you have 2 identical symbols in that space on the paylines.

Special Symbols

Wilds – There are 3 different Wild symbols: The Regular Wild, which substitutes for all symbols other than Free Spins; The Double Wild which also substitutes for all symbols other than Free Spins but is classed as two separate Wilds; and The Lucky Wild, which is only available during Free Spins, is a “Lucky Tree” symbol and will award an additional spin every time one lands along with substituting for all symbols other than Free Spins.

Free Spins – To Trigger the Free Spins feature you need to land 5 or more of the Free Spins (which can land as doubles) anywhere on the reels on a single spin.

Bonus Features

Random Wild Feature – This random feature can trigger at any point but only during the base game. When it does, between 2 and 6 Wilds symbols will be added to the reels, in random positions.

Free Spins – If you land 5 Free Spins symbols you will be given 10 Free Spins. Every Free Spin symbols that you land above the 5 needed to trigger the feature will give you 1 additional spin. If a Lucky Wild symbol lands you will gain 1 additional spin and the space that it lands on will become a double space of the rest of the feature.


Double Lucky Line is all about that middle row that turns all your symbols into doubles. As central features go it is a good one but it is about as good as things get for this slot. It doesn’t look all that inspiring but you do get Free Spin and they can come with additional spins too. The house edge is OK and that is how I would describe this slot: OK.
