title: "Grinch's Lottery"
description: "The Grinch has opened a crooked Christmas lottery stand, tempting villagers with the promise of a “shiny present” that no one could ever afford through honest means. But his ancient 32-bit coin ledger is riddled with flaws, and only someone clever enough to twist his shady loan system can outsmart him and steal the holiday prize."
