House of 9 Dragons, the latest game in IGT’s Multi-Level Progressives series, combines the multiple-progressive format with “MultiPLAY,” the configuration that offers the player the option to bet on up to four individual reel sets, each with its own independent spin.
This is offered in a multi-game configuration with two choices of base game, “Coral Reef” and “Saguaro.” Both are 50-line penny games with 1,000-credit maximum bets. The player can bet from one to five credits per line on each of four games—the minimum bet to activate all four screens is 200 credits.
With all the paylines covered, the Coral Reef game offers 1,024 ways to win on each spin, with a wild symbol that can multiply jackpots up to 10X. Saguaro features stacked wild symbols.
During the base games, players collect a free game each time three scattered golden dragon symbols appear on the reels. Up to 400 free games can be accumulated and played out during the bonus. Players lose accumulated free games if they go more than 30 seconds without playing, or they cash out. A warning screen alerts players they are about to forfeit their collected free games.
Every five minutes on average, the “House of 9 Dragons Group Feature” is initiated. This is a communal bonus event that allows players to choose four dragons that correspond with four of the nine progressive award levels. When the free games are played out during the bonus, dragons may appear on the reels that correspond with the selected four progressives. When five of the same colored dragon symbols appear during free games, that progressive is awarded. Progressives can be won multiple times. Once players have completed their free games, they transition back to the base game.
