With Trainyard Trinkets the objective is to collect as many screw-nuts as possible. There’s no puzzle that requires specific words, however you do need to think strategically. Longer words will collect more screw-nuts than shorter words. Gather enough screw-nuts and you’ll discover all kinds of trinkets on the trainyard.
💡 TIP: Upgrading your letters will dramatically increase the amount of screw-nuts you collect with each word.
