A free Japanese-language browser card game where players combine weapons and enhancements, then defend against attacks with shields of matching attributes.

Why it surfaced

ARCANUM DUEL turns inventory management into a five-minute guessing duel: weapons can carry up to two enhancements, while only the right defensive attribute blocks an attack completely. It includes solo dungeon runs, ranked and casual matchmaking, and private winner-stays-on battles for up to six players—all without installation or mandatory registration.

A File Musicians Can Argue With

August 7’s newborn domains include editable orchestral scores with up to 33 staves, 15 years of Valencia council interventions, a dementia-friendly frame with one optional button, and a memorial golf tournament whose winner wears the Meatball Jacket.

This is one of 1,000 discoveries in the 2026-08-07 Domain Arrivals issue.
