The three things sold as "WePoker 外挂"
1. A solver overlay (real). Tools in this family read the table and feed it to a GTO engine — the same math behind PioSolver, MonkerSolver, or research bots like Pluribus and DeepStack. They don't break the app; they out-think opponents. They're real, but they're slow, need a clean capture, and produce the consistent stats that get accounts reviewed.
2. Pure fantasy (scam). Anything promising 透视 or 控牌 is selling a capability that doesn't physically exist on a server-dealt app. The product is the payment page, not the software. Often it ships malware or a wallet drain instead.
3. Free tools, repackaged. A large share of paid "外挂" is open-source or trial solver software with a new logo and a markup. You're paying for a download you could get yourself.
A 30-second test before you pay
Ask the seller one question: "My cards are dealt on your server — what exactly does your tool read on my device to know my opponents' hands?" A real assistant vendor will say it reads nothing private and only suggests plays from public board info. A scammer will dodge, change the subject, or promise it "just works." That single answer sorts most listings.
Comparing WePoker to PPPoker or ClubGG? The app changes, the physics don't: club-based, server-dealt apps all share the same hard limit on what client software can see.
