Idle RO

Idle RO

Idle RO is a browser-based idle auto-battler RPG built on classic pre-renewal Ragnarok Online systems — the same job classes, skills, monsters, cards, and combat formulas, reimplemented so a party keeps hunting, looting, and leveling even while the player is away.

Gameplay

Players build a party of characters across 12 jobs and 68 skills, sending them through 104 authentic maps (416 stages) across four difficulty tiers to fight 213 monsters and 11 MVP bosses. Combat runs on faithfully-ported pre-renewal formulas (ASPD, soft/hard DEF, elemental modifier tables, refinement odds). Equipment, 198 collectible cards, and gear refinement round out the RPG loop, with offline progress continuing at a reduced rate.

On-chain economy

Idle RO layers a player-owned economy on top of the RPG core: in-game loot grinds into vZeny, an off-chain currency that can be converted into $ZENY, the project's SPL token on Solana, through a conversion gateway. A planned player-to-player marketplace will let equipment, loot, and cards change hands, with trading fees and other sinks burning $ZENY. The team states there is no dev token allocation and roughly 50% of supply burned from day one.

$ZENY went live on pump.fun on August 7, 2026, the day before the game's stated early-access launch (August 8, 2026); the mint was posted directly from the project's own X account.
