# Sneak attacks per round [duplicate]

I attacked someone that is prone. So I attack with advantage plus sneak attack. Then in his turn he leaves my space which grants me an opportunity attack.

Here's my question: does that opportunity attack grant me another sneak attack? Assuming he is in front of my ally too so he is distracted and he did not disengage.

Okay, let's break it down:

A sneak attack is not any sort of action. It doesn't use your action, bonus action, or reaction. It is simply extra damage added onto an attack that meets the requisite conditions. Those are:

\begin{array}{ccc} \text{you have advantage}^1 & & \text{finesse weapon} \\ \\ \text{OR} & \text{AND} & \text{OR} \\ \\ \text{you don't have disadvantage and} \\ \text{you've an ally who isn't incapacitated} && \text{ranged weapon}\\ \text{within 5' of your target}\\ \end{array}

(Basically, you need one from the first column, one from the second.)
