If you are over rank 150 in Puzzle and Dragons, you now have the option to tackle a dungeon with a friend that is at least rank 10. All you have to do is create a room under the Multiplayer Dungeons menu option and share that number with a friend or enter the room ID you have received.
Once in the dungeon, both players will use the same board. Each turn lasts three minutes, any longer and the turn is forfeit. If you don't see any good moves, the option to pass is available once per dungeon. If one player abandons the game, it will switch to single player mode. The person that created the room has the ability to use magic stones and continue. As of right now, there are 22 dungeons to master.
Not all players will have access to the multiplayer dungeons at this time. Those of you with an iPhone 3GS, iPod Touch 4th generation, or an Android phone with Android OS 4 or older are out of luck. If you do have a compatible device, the multiplayer option has already launched.
