Tower of Hell: Obby Blox turns your screen into a vertical gauntlet. Classic mode, pure skill. No fluff. No checkpoints. Every floor fights back moving platforms, tight ledges, spinning traps. Miss a jump, eat the fall, shake it off, go again. The tower keeps stacking pressure; you keep dialing in your timing. The tower don't care. Controls is simple: run, jump, climb mastery is not. Smooth restarts keep the flow alive, short runs make improvements feel instant. It's the classic challenge you know and love, right in the browser on your computer or phone, no installs and no excuses. Each attempt sharpens your nerves. Each fall humbles. Each clear feels ridiculously good. Hit Play and start the climb.
