Tintin and Snowy are having a day that starts ordinarily enough — until a mystery assembles itself around them. Snowy gets his snout stuck in a crab tin. The Thompsons are investigating counterfeit money. A stranger is kidnapped before he can deliver a letter to Tintin. All of these threads lead somewhere much larger, and Tintin follows them from familiar streets to foreign cities along the trail of The Crab with the Golden Claws. A mobile match-three puzzle game following the plot of the classic Tintin adventure.
