WorldsHardest-Game.com exists for one reason: a stubborn little red square has been ruining keyboards since December 2007, and we think it deserves a proper home. This site keeps World's Hardest Game playable in the browser, with no downloads and no accounts.
We also keep our own notes on the game: which levels stop most players, which routes actually work, where the safe spots are. That's what the level guides on this site are: fail counters we ran up so yours can stay lower.
If a level is eating your fail counter and the guides don't cover it yet, tell us: the guides grow in whatever order players get stuck.
Start with the original Worlds Hardest Game, browse the whole series, or study the level guides before you play. Parents can read our Information for Parents, and if you want to reach us, the contact page is always open.
