What’s worked for me: before I play, I set a custom client seed and screenshot the pre-commit server-seed hash so I know what I’m locked to. During the session I jot the first and last nonces in a mini note. After the seed rotates or I’m done, I feed the revealed server seed + my client seed + nonce into a verifier (any SHA-256 tool works) to check a few random rounds. On mobile, I keep a notes template with placeholders and use a lightweight hash app, so I’m not juggling browsers. For a compact rundown of features I’ll skim dealgamble.com/casino/millioner/ first, then do the proof myself. If the revealed seed reproduces the same round results I saw live, I’m satisfied; if not, I bail.
