Google has added the ability to play games within search results. When you Google solitaire or tic-tac-toe, you'll be invited to play a game.
Each game lets you pick a difficulty level, while tic-tac-toe lets you play against another person provided they're sitting beside you.
Google has also implemented the option to flip a coin by typing in "coin flip." That could settle a few stalemates without the possibility of someone rigging the result.
It will be interesting to see if companies feel the effect of these new additions. RescueTime estimated that 4.82 millions hours of productivity in the US were lost when Google released its Pac Man Google Doodle in 2010.
