This feature is active throughout the base game and free spins mode and consists of a frame that sits across the centre of the reels. This frame converts any symbols that land within its area into double symbols. Their value is doubled and added to your winnings when you create a winning combination.
Wild symbols can randomly turn 2 to 6 other symbols into wilds, potentially creating wide combinations across the reels and a huge win.
Landing 5 scatter symbols sets of the free spins, with each subsequent scatter over 5 gifting you one extra free spin. The maximum number of free spins you can get this way is 25. During the free spins, special lucky wild symbols convert their current positions into double symbol positions and award you an additional free spin.
Double Lucky Line suffers by comparison to other Asian-themed slots from both a presentation and gameplay perspective. Any excitement you may feel at the combination of features is likely to be dampened by medium volatility and a painfully average RTP of 96.02%. The game feels like a rushed re-skin of tweethearts, a previous title by the same developer, with the game mechanics being all but identical. Reaching the top-end of winning in this game would involve a lot of spins and it fails to inspire with its presentation, meaning that this slot is unlikely to find an eager audience willing to part with their money.
