Thai Number Lab
Thai numbers are regular until they are not. Build them, hear them, and decode the two places you will actually meet them: prices and phone numbers.
No signup. Five ways in.
Today’s Plan brings numbers in early, because a price you cannot hear is a transaction you cannot finish.

What a round looks like
Build them, then decode them in the wild
Five modes, and two of them are real situations
Number Builder and Hear & Build teach the construction. Price Decoder and Phone Challenge are the two places numbers actually arrive — spoken fast, in chunks, by someone who is not slowing down for you. Confusion Busters handles the pairs that catch everyone.

The irregular bits get their own drill
Eleven is not "one-one", twenty is not "two-ten", and the word for one changes shape in compounds. Those are the rules that make an otherwise regular system feel broken, so they are drilled directly rather than left to trip you.
Phone numbers are read in chunks, not digit by digit — which is why they get their own mode rather than being treated as long numbers.

Counting things
Thai counts with classifiers, and the word order is its own skill.
