# Closest Guess > ⚠️ **Experimental — generated with no human supervision** by the daily MCP pipeline to exercise gno tooling. Not audited. See [r/moul/x/daily](https://github.com/moul/gno-contracts/blob/main/r/moul/x/daily/README.md). --- A blind, multiplayer number-guessing puzzle: submit one silent guess per round in 1..1000, then anyone calls Reveal() to disclose the hidden target and crown whoever landed closest. No hints, no iterative narrowing — just one shot and a leaderboard ranked by smallest distance across all-time rounds. It's a deliberately different twist on the genre from higher/lower or bulls-and-cows: the suspense is in not knowing until reveal. Built for sapphire (gno 0.9). Live demo (agent address): https://sapphire.testnets.gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/closestguess ## What changed in v1 Identical behaviour to [`v0`](https://github.com/moul/gno-contracts/tree/4f2df83869b80470eb81c48a82fdbe82256b8113/r/moul/x/daily/closestguess) apart from rendering, which now goes through [`p/moul/kit/ui`](/p/moul/kit/ui/v0) instead of the local `shortAddr` helper. **One address format.** Eleven realms carried their own `shortAddr` with four different truncation rules, so the same account rendered differently depending on which realm you opened. `ui.Addr` is that decision made once: 8 leading characters, an ellipsis, 4 trailing, in backticks. Visible change: addresses now render in monospace. The rendering change means the output differs from v0, which under this repo's versioning rule is a compatibility change, hence a new version rather than an edit in place. `v0` stays live and untouched. --- Part of **[moul/gno-contracts](https://github.com/moul/gno-contracts)** — moul's versioned gno.land contracts.
