Feeling lucky?

It shouldn't be available at all times, like maybe every 12 hours you can use it once? Making it more rare.
Also, it can be gambling with items too, and whenever you want to ''double'' your win, your chance of winning decreases? Hehhe 50% is too easy

enabling a delay takes away from a main part of what gambling is--increasing the excitement and possible reward without guarantee for it. Players who lose a lot in a row may be entitled to spending more as they think continuous losing gives them a higher chance of winning (even if not true), so there should not be a delay imo.
