closestguess/v0 package

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

Guess

func Guess(cur realm, n int) string

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).

Render

func Render(path string) string

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.

Param

Command

gnokey query vm/qeval -remote "http://127.0.0.1:26657" -data "gno.land/r/moul/x/daily/closestguess/v0.Render()"

Result

Reveal

func Reveal(cur realm) string

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.
