func Guess
crossing ActionGuess records the caller's single blind guess for the current round. It returns no hint about correctness — that is the whole point of the puzzle. Crossing function: caller invokes as Guess(cross(cur), n).

Closest Guess
⚠️ Experimental — generated with no human supervision by the daily MCP pipeline to exercise gno tooling. Not audited. See r/moul/x/daily.
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 apart from rendering, which now goes
through p/moul/kit/ui 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 — moul's versioned gno.land contracts. See the repository for the full catalog, build/test tooling, and usage.

Package closestguess is a blind, multiplayer number-guessing puzzle.
Unlike a classic higher/lower guessing game, closestguess gives NO feedback per guess. Each round hides a target in 1..1000 (derived deterministically from the block height the round started at); every address may submit exactly one blind Guess for the round. Whenever someone calls Reveal, the round closes: the target is disclosed, the guess with the smallest absolute distance wins (ties go to whoever guessed first), the winner is recorded on the leaderboard, and a fresh round starts immediately.

func Render
Render produces the gnoweb Markdown view. The current round's target and individual guess values are never shown — only the player count — so rendering the page can't leak the puzzle.
func Reveal
crossing ActionReveal closes the current round: discloses the target, crowns whoever landed closest (ties favor the earliest guesser), records a leaderboard entry, and opens a fresh round. Panics if nobody has guessed yet. Crossing function.
