Casinos offering Mermaids Millions
Mermaids Millions Slot is a five reel, fifteen payline, and seventy-five coin slot machine.

Mermaids Millions has a wild symbol, a scatter symbol, a Free Spins bonus game and a Treasure bonus game.

The Neptune symbol is a wild symbol and therefore it substitutes for other symbols to complete winning combinations. However it does not substitute for either the Mermaid symbol to complete scatter winning combinations or the Treasure Bonus symbol to trigger the bonus game.

The Mermaid Millions symbol is a scatter symbol. This means that it does not need to appear in a line on an enabled payline, to win. Three or more Mermaid Millions symbols displayed on the reels activates the Free Spins bonus game, and you are awarded ten free spins. In order for you to qualify for the Treasure bonus game you need to have three or more Treasure Bonus symbols displayed in a line, on an enabled payline. The Neptune symbol does not substitute for the Treasure Bonus symbol to trigger the Treasure bonus game.

Examples:

• If you select a 0.50 credit coin and bet 5 coins per payline. You bet on all 15 paylines. So, your total bet amount is 0.50 credits x 5 coins = 2.50 credits bet per payline x 15 paylines = 37.50 total credits bet. If three Ace symbols are displayed on reels 1, 2 and 3 on Payline 1, they complete a 3 Ace symbols combination and pay out 10 coins. Therefore, you are paid 10 coins x 2.50 credits bet per payline = 25 credits.
• If you select a 0.50 credit coin and bet 5 coins per payline. You bet on all 15 paylines. So, your total bet amount is 0.50 credits x 5 coins = 2.50 credits bet per payline x 15 paylines = 37.50 total credits bet. Three Clam symbols are displayed on reels 1, 2 and 3 on Payline 1. They complete a 3 Clam symbols combination and pay out 20 coins. Three Ace symbols are displayed on reels 1, 2 and 3 on Payline 3. They complete a 3 Ace symbol combination and pay out 10 coins. So, you are paid 20 coins x 2.50 credits = 50 credits for Payline 1, and 10 coins x 2.50 credits = 25 credits for Payline 3, as you bet 2.50 credits per payline. Therefore, your total payout is 50 credits for Payline 1 + 25 credits for Payline 3 = 75 total credits.
