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

Overview

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.

Functions 3

func Guess

crossing Action 
1func Guess(cur realm, n int) string
source

Guess 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).

func Render 

1func Render(path string) string
source

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 Action 
1func Reveal(cur realm) string
source

Reveal 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.
