Jotto Solver

Jotto is a two-player word and deduction game in which each player secretly chooses a five-letter word.

On each turn, the user submits a guess and receives a score indicating how many letters are shared between the guessed word and the opponent's secret word, regardless of their position.

The first player who correctly discovers the opponent's secret word wins the game.

The rules of Jotto are based on four simple steps:

— Each player secretly chooses a five-letter word

— Players take turns submitting a guess

— After each attempt, a score indicates the number of letters shared between the guessed word and the secret word, without revealing their position

— The first player who correctly finds the opponent's secret word wins the game

The basic strategy is to use words containing common letters such as E, A, S, I, N, R, T, O, L, or U.

The goal is to quickly test a large number of letters likely to appear in the secret word.

After each attempt, the user can eliminate all words incompatible with the observed constraints and progressively reduce the space of possible solutions.

Repeated letters are one of the main difficulties in Jotto. A letter contributes to the score according to the minimum number of times it appears between the tested word and the secret word.

The score for a letter is the minimum between the number of occurrences of the letter in the guess and the number of occurrences of the letter in the secret word.

From a strategic perspective, using repeated letters can provide a large amount of information, but it also makes scores more difficult to interpret.

To reduce ambiguity at the beginning of a game, it is generally preferable to use secret words without repeated letters.

A score of 0 means that none of the letters in the proposed word appear in the secret word. All tested letters can therefore be excluded from future hypotheses.

A Jotto Solver helps the user quickly reduce the number of possible words after each attempt.

It automatically eliminates words incompatible with the observed constraints and can suggest optimal words in order to maximize the information obtained at each turn.

This type of tool is particularly useful for practising lexical deduction and combinatorial strategies.
