Mental arithmetic

Filomath

Word placement

Septimo

Seven letters, a board of eight squares where some double or triple, one word to play per round. The longest word is not always the best move: it comes down to the letters, their value and the squares they cover. Five rounds of thirty seconds, and after each one, the best move that was possible.
