User reviews

Definitely like an updated Rubix cube

Nice game, the trick is, when ever an "o" is on a square and it's on, then any "o" will turn the square on. Otherwise any "n" will turn it on. Once you've got that it's just shifting until you get pieces in the right places. Cool idea.

Assez sympa

Trouver la bonne combinaison pour allumer tous les blocs, c'est assez sympa et les nombreux niveaux permettent de jouer longtemps !

Bon jeu de réflexion

Pas mal comme jeu, assez fluide, original et intéressant.

Gutes Knopelspiel

Ein gutes Spiel für zwischendurch.

Unique

Interesting and has a certain unique charm about it. Nicely made.
