An annual bonus is usually based on overall company performance. This means you may get a large or small bonus (or no bonus at all) depending on how successful your organization or specific department was that year, as well as how big a part of that success you were. This can also be considered profit sharing. 

A bonus stage (also known as a bonus level, bonus round, or special stage) is a special level within a video game designed to reward the player or players, and typically allows the player to collect extra points or power-ups.
