I encounter this problem 5 months ago.Day1 i say OK.Day 2 i try a different browser , clear cache , history etc . Still didn't get the 50 extra stamina .

What i do in order to get the bonus stamina is : Stay in hotsprings while in browser for 1:57:00 (or 1:58:00 if you are a Jonin Medal user) then exit . Resume Hotsprings proccess from the mini client and you get the bonus 50 stamina . I know this can be frustrating but this is the way i get the bonus

What 50 stamina? I've been playing this game for almost a year now I never encountered that before.

i always get it as long as i don;t leave the hotspring before the full timer has finished

you get the +50 stamina if somebody else use soap on you. If none does it you don't get the stamina.

@singsing

Dont join hot spring when u play on puffin, at least u should have 3 mins before time runs out n move to browser or client. Puffin never give u bonus 50 stamina.

@Shadoblaze

Thats not true. Im always out in the baths but i can still get bonus.

i afk the hot spring in my browser but never get the 50 stamina boost, however i did get it when i was using the mini client
