Vertex is the casino lobby people actually stay in: Crash, Mines and Limbo, each with a fairness story you can show on a /fairness page instead of hiding in a footer.

Crash uses a hash chain published in advance, so every future crash point is committed before the first bet. Mines and Limbo derive each result from a server seed the player already hashed. The verifier runs in the browser with Web Crypto — the same mapping the server uses.

Inside the pack: - Crash with live rounds, cash-out, and a seed chain you can audit - Mines with start / reveal / cash-out, including the ugly mid-round cases - Limbo with a clean multiplier input and instant settlement - Session balances held in memory (play money — no deposits, no withdrawals) - A fairness page that lets a sceptical player check the last result themselves

If you have been asked for “a crash site that does not look like a clone farm”, this is the one you put in front of them.
