A second-hand deal looks fine. Check the clues, question the seller, then buy or pass.
I'm an indie developer in South Korea. I made a deduction game about a familiar question: is this second-hand deal really worth buying?
A seller says the item works — but what did they actually test? Read their answers, check listing photos and appraisal records, and compare completed sales before you decide. Each commission gives you limited focus, so you also choose which clue to investigate first.
There are 60 campaign commissions, including boss deals with multiple items and changing terms, plus a Daily Market.
Available on iPhone, iPad and Android. Free to download, with optional rewarded ads and in-app purchases. The items and coins are only for gameplay; there is no real-world trading or cash redemption.
AI tools were used for artwork, translation and music. The screenshots are the game's English App Store images.
