About Portal Flash

Portal Flash plays instantly in the browser, which makes it an easy game to try and (fair warning) an easy one to lose an hour to. What it asks of you is obvious within seconds; how well you answer is the actual game.

You'll need keyboard and mouse and not much else. It plays fine on mobile as well, which makes it dangerously portable. Scores here are personal: the only leaderboard that matters is your last attempt.
