Patterned after the 2004 Slot Machine of the Year, Tomb Raider, this five-reel, 15-payline slot game features an underwater riches theme. Microgaming decided not to change the successful format too much in designing this piece of software, so those who are fans of the Laura Croft action adventure should feel right at home searching for wealth beneath the waves.
Mermaids Millions slots employ the traditional card symbols, Tens through Aces, as the lowest valued winning combinations, paying from 2X to 125X for three or more matched symbols on an active payline. Higher awards come from lining up three or more Seahorse, Raw Pearl or Jewel Box symbols at multipliers from 15X to 500X.
The King Neptune symbol is wild, substituting for all symbols except the Mermaid scatter and Treasure Chest bonus symbols. Catching 2, 3, 4 or 5 King Neptune symbols in a row on an active payline pays 5X, 200X, 2,000X or 7,500X for the largest single line awards of all on this game. Catching 2, 3, 4 or 5 Scattered Mermaids anywhere on the reels multiplies the total amount wagered by 2X, 4X, 50X or 400X, respectively.
Credit denominations range from €0.01 to €1.00 and up to five credits can be bet per line for a max bet of 75 credits or €75. The credit value can be adjusted by clicking on the +/- buttons under the second reel. To start the game, click “Spin.” The reels can be halted instantly by clicking “Stop.” Winnings appear in the “View Payout” display below the third reel, while the current Coins balance appears in the lower left corner of the screen. Use of Autoplay in the Expert mode allows up to 50 respins at the same bet level.
The bonus rounds on Mermaids Millions slots were state-of-the-art when they were introduced. Three or more Scattered Mermaid symbols trigger ten free spins with all wins tripled. This bumps the top jackpot up to a staggering 112,500 credits. What’s more, the bonus can be retriggered indefinitely, while all bets and lines played during the free spins mode are the same as the game that started the free spins.
The other big bonus round available on Mermaids Millions slots is called the Treasure Bonus. It is initiated by catching three or more treasure chests on an active pay line, aligned left to right. In the Treasure Bonus mode, the regular slot game disappears to be replaced by a scene on the bottom of the ocean. There, seven Treasure Chests, three Giant Clams and two Sunken Barrels appear. Depending upon the number of bonus symbols that triggered the round, the player may select 3, 4 or 5 of these objects to reveal rewards.
The contents of the objects on the ocean floor are also determined by the bonus symbols that triggered the round. When three objects are to be selected, the prizes range from 36 to 1,500 credits. When four are to be chosen, the reward varies between 48 and 2,000 credits per pick. And with five objects to be selected, the contents range from 60 to 2,500 credits inside each.
Because there are just eleven symbols in play in the main slot game, with 35 winning combinations possible, small and mid-range wins are frequent, and the game’s overall volatility is ranked as medium. Getting the top prize of five King Neptune symbols is worth €37,500 at max bet. The second highest pay is €30,000 coins for five Scattered Mermaids at max bet.
