Survivor mode can be found from the Main Menu by clicking on "Play Survival." For these achievements, you need to serve a total of 25 customers in one play of this mode. You continue serving customers until a single customer loses all of their hearts and walks out. In this mode, your spa starts out small and expands as time progresses. More chairs and new treatments appear, as well as item that help you out, like magazines, candles, and tea. Employ the same strategies used in Story Mode, with one notable exception. There is no need to worry about checking customers out with 5 hearts, so do not waste your resources on doing so. Just ensure that no customers lose all of their hearts. Use candles at will as they respawn after a short time and constantly keep the tea machine going. Getting 25 customers through the spa is not difficult at all. These achievements will unlock when you finally lose, at the end scoring screen, not mid-game.
