Most people go to social networks on their phones when they’re bored at work. Most, but not all. The video above posted on twitter shows two construction workers playing tic tac toe instead.

Nothing unusual there either, but it’s just that these two chose to play their game using the road as a surface and construction drills to make their noughts and crosses. Beats paper and pencil any day.

The result of this fierce and gripping contest was not evident from the viral video, which ended before the game did. But, inevitably, someone on twitter established who won. And others had their own observations.
