I love this game and the other games from this developer. That being said, this is my favorite because there is always logic behind every decision and there’s a sense of gratification whenever you complete a puzzle (even the easy ones!).

I read the tutorial several times and I still don’t understand how the game works. I think that the tutorial should be reworked. I’m surprised that a company like Simon & Schuster would put their name on a product that has so many grammatical errors.

Although I received the yearly sub for free from a promo, I plan to support this app with the yearly sub. It has daily and weekly challenges that users can participate among face to face friends and players around the world. If competition is not your alley, numerous sets ranging from easy to difficult are provided. I certainly think the amount of content more than justifies the price especially with the recurring costs of the online features. If I am not mistaken, the Sudoko-flavored game is called str8ts (citation needed). The UI works for mobile. The only feature I want to be fulfilled is web browser support so I can play this game from any device.
