Sky Coins by Booongo is a 3x3 slot set against an Oriental sky theme, with lantern imagery and a coin-collecting format. The game uses the HIT THE BONUS mechanic, where filling the middle row with symbols triggers three initial respins and starts the bonus game sequence. Players can use the demo version to play for free and practice before playing for real money.
The bonus round is built around several special features. A Sticky Bonus Symbol remains in place until the bonus game begins, while Bonus Symbols may carry MINI, MINOR or MAJOR jackpot values. A Mystery Jackpot Symbol can transform into one of these jackpot outcomes at the end of the bonus game, and a Mystery Symbol can become any other symbol except the Sticky Bonus Symbol. Filling all reel positions creates a chance to reach the Grand Jackpot prize.
Sky Coins also includes a random Multiplier Feature that can award up to nine multipliers, plus a Collect Symbol that gathers prizes from current Bonus, Sticky Bonus and Jackpot Symbols. Filling the Sky Lantern Meter with Bonus Symbols unlocks the Ultra Bonus Game, which comes with a guaranteed Multiplier Feature.
