Train Drill

All-new landscape design! Now with Subtraction mode and English support.

Learn addition and subtraction through train coupling and uncoupling.

Two trains couple with a satisfying "clunk!" — how many cars in all? Cars uncouple from the consist — how many are left?

The coupling and uncoupling animations turn numbers into something you can see and count, so arithmetic sinks in through play.
