Rules and play
Mathler Game Rules
A new target appears each day. Submit a legal equation using 0–9 and +, −, ×, ÷. Order of operations applies. Feedback colors each character independently. Keep submitting valid equations until the whole line is green. A line that does not equal the target is rejected, so Mathler blocks the usual “throw letters to see colors” habit from word games.
- Find Mathler’s hidden equation that equals the posted target.
- Green locks a digit or operator in place; yellow means relocate it; gray drops it.
- Every submitted line must evaluate to the target.
- A new Mathler equation appears daily.
