Board Game Arena

Hi guys! I have an easy question today. This is my information about a game I play here on BGA. But what does the number in the parenthesis after the number if games mean? In my case the (+2), just to be clear. Are those the number of games played in training mode? Or what?

My achievements
302
59th
186 Games (+2)
114 Victories

Yes this is the training mode, Alpha, and solo mode number.
On computer when you pass over with the mouse pointer it is said in a bubble text.
