Double Lucky Line slot
Double Lucky Line is an East Asian-themed slot that Just For The Win made for Microgaming, released in January 2020. It looks like a 5x3 game, but each of its 15 positions spins as a reel of its own, and it pays on 17 lines. Every middle-row symbol is a double that counts as two, so one line can pay for more than five of a kind, and the free spins add Lucky Wilds that create more doubles.
Editorial note: this guide explains how Double Lucky Line works. Rules, features and payout figures are set by the studio and can differ between operators and game versions, so check the game’s information panel before you play. Slots are games of chance, and nothing here predicts results. Availability at Fortune Games can change.

How Double Lucky Line plays
The screen shows a familiar five-by-three block, but the game treats it as 15 separate reels, each spinning on its own. Wins are paid on 17 paylines for three or more matching symbols. Card symbols fill the lower end of the paytable, with a turtle, a frog and a dragon above them and the game logo at the top.
Double Lucky Line in our lobby on 12 November 2026, at £1 a spin: a 5x3 grid with a double symbol in each middle-row position and single symbols above and below. The bar above the game shows “Net position: £0.00” and a timer. UK rules require online slots to show time played and net position. Game and artwork © Just For The Win.
What sets the game apart is the way symbols are counted. Some arrive as doubles, worth two of their kind, and the game adds up how many of a symbol a line holds rather than how many positions it covers. That is why the paytable runs past five of a kind, as explained in the questions below. Volatility is rated medium.
The Double Lucky Line
The middle row gives the game its name. Every symbol that lands there is a double, so any line that passes through the middle row picks up two of whatever lands in that position. Three matching symbols in the middle-row positions of a line therefore count as six. Doubles are not limited to that row, as they can also land on the top and bottom rows.
Wilds and the Random Wild feature
There are two kinds of wild in the base game, matching the two kinds of symbol: a single wild that stands in for single symbols and a double wild that fills in for doubles. The Random Wild feature can strike on any base-game spin and adds between two and six wilds to the grid at random positions, which can complete lines that the reels alone left short.
Free spins
Five or more scatters anywhere start the free spins with 10 spins, and every scatter beyond the fifth adds one more, up to 25, so seven scatters on the triggering spin give 12. Scatters can land as singles or doubles. During the round a third kind of wild joins the reels, the Lucky Wild, which is covered in the questions below.
The free spins rules in our lobby: 5 free spins symbols give 10 free spins and each extra one adds a spin, and each Lucky Wild adds a spin and turns its position into a double for the remaining free spins. Game and artwork © Just For The Win.
Double Lucky Line at Fortune Games
Double Lucky Line’s own stake range starts at 10p a spin, and the UK caps set the top at £5, or £2 if you are 18 to 24. You will find it with the other slots in the Fortune Games lobby (18+), and the tiles above include Double Lucky Mushrooms DoubleMax, which shares the word double but comes from a different studio. Fortune Games has an app on the App Store and Google Play.
Frequently asked questions
How can Double Lucky Line pay for ten of a kind?
Because doubles count as two. A line covers only five positions, but if each of them holds a double of the same symbol, or a double wild in its place, the game counts ten. The paytable therefore lists prizes beyond five of a kind, and its top prize is for ten of a kind.
What does the Lucky Wild do in Double Lucky Line?
It appears only in the free spins, where it is the third kind of wild alongside the single and double wilds. When it lands, it acts as a wild, turns its position into a double position and adds one free spin to the round, so it can make the round longer as well as complete wins.
Is Double Lucky Line the same game as Tweethearts?
In everything but looks. Just For The Win made Tweethearts first, with the same double symbols, wilds and free spins, and Double Lucky Line re-dresses that game with an East Asian theme and new symbols. The rules described on this page therefore match Tweethearts too.
