The guessing game

Don't play it. It might look tempting but don't i lost 200 sg.

I mean, it's usually a bad idea to gamble, especially since you spend at lieast 100 SG on that thing.... but if you get lucky, well, good for you. But i wouldn't recommend it trying it either

well unless you want to try your luck otherwise don't play it, for once I won over 1000 gems but then lose them all
and those gems you lost may could exchange with some other rewards or chest

if you just got your 100 gems and wanted to try your luck just do it to see if you could get 200 gems or more (if you're lucky)

The guessing game is not available here but does it help to get gems faster?

well it's a gamble. if you win, then yes. but there's a chance you lose your gems
