v0 state

round

round holds the mutable state of the active game round.

winRecord

winRecord is one leaderboard entry.

init.5

newRound

newRound builds a fresh round whose target derives deterministically from the start height. Gno has no runtime RNG, so height is the only entropy.

targetFromHeight

targetFromHeight maps a block height to a hidden number in 1..100. Deterministic and cheap: a small integer mix so consecutive rounds don't land on obviously adjacent targets.

Guess

Guess submits a guess for the current round. It records the caller's attempt count and returns "higher", "lower" or "correct". Crossing function: caller invokes as Guess(cross(cur), n).

NewRound

NewRound resets the game with a fresh target when the current round is solved. Panics if the current round is still open. Crossing function.

incAttempt

incAttempt bumps the caller's attempt counter for the current round.

attemptsOf

attemptsOf returns how many guesses addr has made this round.

totalAttempts

totalAttempts sums all attempts made in the current round.

Render

Render produces the gnoweb Markdown view of the current game state.

renderLeaderboard

renderLeaderboard formats winners ranked by fewest guesses (ties: earlier round first). Sorted on a copy so state is untouched.

sortByFewestTries

sortByFewestTries does an in-place insertion sort: fewer tries first, then earlier round first on ties. Small n; insertion sort keeps it deterministic and dependency-free.
