A single player can play the game as a solo experience by controlling two or more characters at once. Part of the game’s difficulty, however, comes from not knowing exactly what the other characters will be doing on their turn. Because a solo player has precise information about what each character is doing and can coordinate more effectively, the game becomes easier.
To compensate for this, solo players should increase the monster level and trap damage by 1 for any given scenario without increasing gold conversion and bonus experience (see table below for updated solo stats).
