Complete rules
This is an original single-player matching challenge, not a simulation of commercial Mexican Train rules.
A yellow signal marks tiles that match the number at the left or right end of the train.
After selecting a tile, use the enabled left or right placement control. The tile flips automatically when needed.
You win when all seven tiles are placed. Daily mode keeps the same UTC deal for everyone; your result can be shared without revealing the tiles.
