The latest game in Konami’s “Xtra Reward” series, Masked Ball Nights features the standard free-spin bonus plus a random extra bonus event that transforms certain symbols into wild symbols.

Games in the Xtra Reward series require the player to cover the lines plus make a 15-credit ante bet to qualify for the additional bonus feature. That bonus feature is unique to each game in the series.

The base game for Masked Ball Nights applies an operatic/costume ball theme to a 30-line video format. The diamond symbol is wild, substituting for all but the bonus-trigger symbol.

The main bonus event is the free-spin round, triggered by three or more scattered masked-woman symbols. The feature awards 15 free games, with all jackpots doubled. The free-game feature can be re-triggered within the free games.

The Xtra Reward bonus occurs randomly at the beginning of a spin, if the player has made the minimum wager covering the paylines with the 15-credit ante wager. With the qualifying wager made, any or all of four symbols—the mask, the fan, the lamp and the carriage—turn into wild symbols at the beginning of various spins. The wild symbols then substitute for all but the masked-woman symbol for that spin.
