WHY YOU'LL LOVE IT
SolaMoon is a free logic game you can play anywhere: no wifi needed — perfect on the train, on a break or before bed. A grid takes two to five minutes, the difficulty rises gently, and every solution is reached by pure reasoning: there is never any guessing.

Fans of takuzu, binairo, binary puzzles, unruly and tic-tac-logic will be at home right away — same rules, softer look. If you enjoy a daily logic grid such as tango, sudoku or nonograms, SolaMoon is your next one.

It is also quiet brain training: counting what is left to place, spotting a pair, reading a sign — mental arithmetic, logic and focus, without ever feeling like homework.
