Plays a good game of 16x16 sudoku, but it has gone from prompting you to pay for the premium at the start of a game and then playing a quick ad, to now making you sit through the premium ad, then three different ads before you can make a move, then when you get back to the game, prompting you to pay for premium and sending you through the obligatory ads all over again. Again, before you even get to play. Just an endless cycle of ads and no gameplay. Pathetic money-grubbing behaviour.

I love the games. I love the different sizes of playing grids. I love that I pick a row, column, and a specific box with the correct numbers and letters that go in those options. This is one of my favorite apps. I play it every day.
