If you ever had access to a computer lab at school, chances are you spent at least one class pretending to do homework while another browser tab was hiding a game. Before mobile gaming took over, free Flash games were the easiest way to waste an afternoon without downloading anything. Some lasted five minutes, while others somehow turned into hours of “just one more level.” Looking back, many of these simple games are just as memorable as the classes we were supposed to be paying attention to.
Here are 15 browser games you secretly played instead of studying.

Two brothers armed with tennis balls somehow became one of the most addictive strategy games on the internet.

Popping balloons with monkeys turned into an obsession once you started unlocking better towers.
The Impossible Quiz
Almost every question was designed to trick you, making every wrong answer as memorable as the right one.
