Train Drill

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. ■ Features - Adventure map with 9 routes: forest, mountains, sea, and the stars - Clear every addition route to unlock Subtraction mode - Train collection: stainless, two-tone liveries, and special cars - Special showcase: Shinkansen, steam locomotive, and a luxury cruise train - Rank up as you answer: Trainee -> Local -> Express -> Limited Express -> Shinkansen Driver - Parents' dashboard: weekly play counts and tricky problems - Built-in daily limits (Free: 3 stages/day) - No ads, all data stays on the device ■ Plans - Free: 3 stages/day - Mini: 10 stages/day + Subtraction mode - Unlimited: unlimited + Subtraction mode ■ Terms & Privacy - Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ - Privacy Policy: https://kuromojilabs.github.io/traindrill-site/privacy.html
