Does anyone think playing a sound effect for winning would be too annoying?
I was reading this article and thought of JD,haha.

>>When you hear the “ding” that you have a text – The dopamine system is especially sensitive to “cues” that a reward is coming. If there is a small, specific cue that signifies that something is going to happen, that sets off our dopamine system. So when there is a sound when a text message or email arrives, or a visual cue, that enhances the addictive effect (for the psychologists out there: remember Pavlov).
