# IOAI 2026 — Potato
|
| 13 |
+
|
| 14 |
+
Official contest data for **Potato**, task 3 (Day 1) of the [IOAI 2026](https://ioai-official.org) Individual Contest, held in Astana, Kazakhstan.
|
| 15 |
+
|
| 16 |
+
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.
|
| 17 |
+
|
| 18 |
+
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**.
