The Celtic Crown is a 5 Reel, 25 Payline online slot machine with a Celtic theme. It was released by Microgaming. Coin size starts from $0.01 and going as high as to $0.25. The maximum jackpot is 10,000 coins. There are also wild symbols, multipliers, scatter icons, free spins, a bonus game and a gambling feature in the game. The princess symbol is the wild; it is also the substitute symbol. When she appears, she can substitute herself for all the icons to produce winning combinations except for the scatter Harp. By the way she only appears on reels between 2 and 4. She also activate the Princess Bonus Feature. The scatter icon is the Harp. It multiples your bet. When it appears on reels between 2 and 5 in any position, it multiply your full spun wager by 2, 5, 20 or 100 times. If you get three or more the free spins bonus feature is triggered.

Three or more of the scatter icon across the reels will reveal their hidden free-spin amounts that you can add and count as your free-spins. Any prizes won through the free-spins are automatically doubled. Not only you can double your prize but also you can re-trigger more free spins by hitting the same combination. That can happen over and over again.

The Princess Feature is triggered by spinning all three of the substitute symbol across the reels between 2 and 4. You will be taken to a screen where 6 knights are waiting to be chosen to give the princess their gifts. Choose 3 of the 6 and they will present the gifts to the princess which in turn will greatly reward your balance. You can even trigger this bonus feature through the free-spins.

The other bonus game is the standard Microgaming gamble feature. Double your winnings by guessing the right color; either black or red or take it a step further and try to quadruple your winnings by guessing the suit of the next card; either diamonds, hearts, clubs or spades.
