    Sigma is an excellent three-match title that provides just about everything you could ask for to make this a thoroughly addictive experience.

    Sigma is an original puzzle game tetris-style. The game is simple but funny, and the low price is another reason to buy it if you like this genre.

    A refreshingly original and pleasingly tactile match-three puzzler that's as fun to operate as it is to solve, all set to a blissful electronica soundtrack.
