How to Play Thirteen Hours - Step by Step
The Thirteen Hours page loads a ~30 KB clock-chain puzzle in an iframe.
Step 1 - press Play
Press Play to inject the iframe (~30 KB). The lobby shows Progress, Infinite, and a theme color row.
Step 2 - pick a mode
Progress opens a level selector with star gates. Infinite starts a score run where cleared clocks spawn new ones.
Step 3 - tap the active clock
The active clock spins. Tap it when the hand lines up with the next clock so the shot connects.
Step 4 - clear the board
Chain every clock before the timer hits zero. Finish with time left to earn a star in Progress mode.

Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
