Check a pool

Paste beatmap IDs or links, a pool (a slot and a map on each line), or a pack key. Each map is checked against the content rules for officially supported tournaments.

A pack key is read first, then slot lines like NM1 129891, then bare IDs and links. Up to 64 maps.

This is a guide, not a ruling: the osu! Tournament Committee decides. It follows the osu! wiki's content usage permissions and official support pages, through the rules of the osu! Mappool Compliance project. Nothing here stops you from using a map.
