• IREAD.IT Alphametic Generator & Solver
  by Giovanni Resta

  An on-line program to solve and create cryptarithms and alphametics created by Giovanni Resta, a senior researcher in the Computational Mathematics section of the Institute of Informatics and Telematics of the Italian CNR. This program can help you find alphametics with unique solution and sum and differences whose result is a meaningful word. For example, given the two words Barack and Obama, among the solutions you'll find "amazes". You can find funny alphametics by entering the names of your friends and then selecting the more interesting words among those suggested by the program. It supports 3 languages: English, Italian and Spanish.
