# IOAI 2026 — Potato
Official contest data for **Potato**, task 3 (Day 1) of the [IOAI 2026](https://ioai-official.org) Individual Contest, held in Astana, Kazakhstan.
A word-guessing game: the judge picks a hidden word from a fixed vocabulary, and the contestant must find it in at most 30 turns. Each turn the judge compares two words and reports which is semantically closer to the hidden word.
The task statement, translations into 45+ languages, the baseline solution, and the grader live in the [IOAI-2026 GitHub repository](https://github.com/IOAI-official/IOAI-2026/tree/main/Individual-Contest/3_Potato). This repository holds **data only**.
