ChuChu Train is a one-stroke puzzle where you pass through train stations in order.
• Connect the rails from station 1 to the very last station without lifting your finger. • Cute little gimmicks like crossings and single-track tunnels keep every level feeling fresh. • Clear a level and watch a postcard featuring a scene from around the world slowly turn to full color.
Sit back and enjoy the puzzle with ChuChu Train.
