Underground Brain Train

Took me a few rounds to get the hang of adding and subtracting my way to the target number, but once it clicked, the puzzle logic is really satisfying. The twelve numbered track tiles force you to think ahead about which connections you're building. My brain actually hurt in a good way after playing

I’ve played through all twelve track tiles twice now and the logic still feels fresh, especially when you’re forced to subtract instead of just adding up. The way each tile’s number fits into the final connected route is so satisfying to solve.

The twelve numbered track tiles make each puzzle feel fresh, and I love how adding and subtracting to hit the target number really gets my brain working. My family has been passing it around the table all week, trying to beat each other’s solve times.
