The Grand Line is long. From East Blue to the New World, every arc of One Piece has its islands, its villains and its defining moments. Treasure Cruise puts them all on a map and lets the player sail through them one island at a time with a crew of their choosing.

One Piece Treasure Cruise is a free-to-play turn-based RPG that follows the One Piece storyline from the very beginning, allowing the player to build a crew of six characters from a roster exceeding two thousand and battle through story stages arc by arc. The core battle mechanic is a tap timing system: each crew member attacks in sequence, and tapping at the correct moment creates combo chains that amplify damage across the whole team. Tandem attacks pair specific characters for combined ability animations. Character progression uses a limit break and evolution system that pushes units beyond their base level cap. A gacha system summons new characters from banner events aligned with story arcs and anniversaries. The roster spans all One Piece eras and includes multiple versions of major characters — Luffy across his Gear transformations, Zoro across his timeline appearances and hundreds of supporting and antagonist characters. The game has been in continuous service since 2014.
