Mermaid's Diamond Online Slot: Random Wild Additions; Free-Spins Wild-Reel Additions
Mermaid's Diamond is a pay-both-ways online slot by Play'NGo, in which adjacent identical icons can form winning combinations in 720 different ways. Precious Gemstones and undersea lifeforms appear as reel elements of a 5-reel grid. The slot screen presents 19 symbols distributed into columns of 3-4-5-4-3 icons, starting from the leftmost reel.
The Mermaid image is the central figure. It poses as Wild Symbol that appears during base games as random outcome of a spin; or as Trident-wielded Wild. The Mermaid Wild may sometimes emerge wholly, or partially as a full-reel, full-body substitute icon. When in the free-spins mode, the Mermaid's diamonds are instrumental to obtaining a full-reel Mermaid Wild image. The latter occurs as additional Wilds brought on by the Bonus Game Diamond Collection Feature.
The Diamond image is the highest paying element. Three (3), four (4) or five (5) Diamonds aligned uninterruptedly starting from the leftmost or the rightmost reel, garner a cash reward equal to 1x, 2x, or 10x the Total Bet. Ruby, Sapphire and Emerald Gemstones represent medium-win elements that award cash prizes ranging from 20% to 250% of the Total Bet. The Stingray, the Starfish, the Squid, and the Snail are low-win symbols with pay equivalents ranging from 10% up to 75% of the Total Bet.
Mermaid's Diamond Online Slot: Trident Wilds Feature
Occasionally during an ongoing base game spin, an unseen Trident strikes the reels. One or two symbols bearing a Trident mark will then transform into Mermaid Wilds.
In the Free-Spins Round, the Trident Force creates a full-reel, full-body image of the substitute icon. The feature does not occur at random. In order to bring on the Wild-yielding force, players have to collect at least five (5) Diamond Symbols.
Mermaid's Diamond Online Slot: Bonus Game Symbol with Divine Intervention Feature
A Treasure Chest image filled with Free-Spin Rewards, poses as Bonus Game trigger-symbol. Mermaid's Diamond slot players have to land five (5) Treasure Chest icons on each reel to activate the bonus round.
Divine Interventions Feature – When only four (4) Treasure Chest icons are in view, the undersea powers-that-be of this slot game, may decide to award the 5th Treasure Chest Symbol that will activate the Bonus Game
Mermaid's Diamond Online Slot: Free Games
A Free-Spins Bonus Round may start with a set of 10, 15 or 25 bonus spins. The number of spins awarded depends on the numeral revealed by one of five (5) Treasure Chests. The round though may extend, since additional bet-free spins can be won while in the free mode. A group of three (3), four (4), or five (5) Treasure Chest images in view as bonus-spin outcomes, correspondingly awards 3, 4, or 5 additional free-spins.
Here, the Diamond Collection Feature activates. Diamond icons landing across the bonus reels fill up the Collection Meter. Every five (5) of the collectible image activates the Bonus Game Trident Wild. The Trident will then strike the symbols in at least one (1) reel, and replace them with a full image of the Mermaid Wild. The Wild image though, will stay only for the spin that completed the Diamond Collection Feature.
