What to write in about
- A game code that stopped working. The hidden games list changes — tell us the code and what happened, and we'll re-verify and update the list.
- Corrections. Wrong number on a tool page, dated info in the Code Mode guide, a typo — all welcome.
- Tool suggestions. Which calculator would save you time every week? The tools section grows from requests.
- Privacy questions. Anything covered by the privacy policy — happy to clarify.
Before you write
If your question is “how do I open the games list”, the answer is on one page: flip Code Mode and type 0000. If a specific game won't load, try the server switch inside the list first — the fix order is in the guide's FAQ.
