The Impossible Quiz 2 is the sequel to Splapp-Me-Do's notorious Flash quiz, and it keeps the joke intact: every question looks like a normal multiple choice, and almost none of them are. The answers depend on puns, misdirection, visual gags and occasionally on something from a question twenty screens earlier.
You get a small number of lives and there are no checkpoints in the classic sense, so a wrong answer near the end sends you a long way back. That's not a flaw — the game is about learning the whole sequence, and the community that grew around it in the late 2000s did exactly that.
Because it's built on misdirection rather than knowledge. Questions are worded to make the wrong answer look obvious, and some require actions outside the four options entirely.
Splapp-Me-Do, whose original Impossible Quiz became one of the best-known Flash games of the late 2000s. This is the sequel.
