In the cheat development scene, a "trainer" is a program running alongside a game that modifies memory to grant invincibility, unlimited currency, or aimbots. A "Web Game Trainer" would specifically target browser-based games. Given that many high-profile browser games use HTML5 and WebGL, a tool labeled "WGT" from pwnhack.com could be a JavaScript injector or a memory scanner for titles like Krunker.io , Slither.io , or even complex MMOs with web clients.
