The best mobile app by far. I virtually downloaded all the sudoku mobile apps in the market and deleted them one by one to keep this one. It also competes well with the fully fledged desktop programs. The only marginal improvement that can be added to this app is the possibility to position the candidates within a cell. For instance place the candidates on the corners of the cell or at the middle of the cell. The ideal would the ability to place individual candidates in a cell left center or right. This option will help determine whether the candidates placed in a cell are the only possibilities or if there are other possibilities. But all in all THE BEST MOBILE APP IN THE MARKET so far. I keep downloading news apps but none is a match. I can talk about the superiority of this app all day long: the choice of fonts, the coloring, the ability to enter one’s own puzzle etc etc.

Daily Player

Great deployment of the Sudoku game. Many options are available for playing, along with different levels of difficulty. The hint function also provides you with an explanation, which increases your knowledge of the game. I typical play Sudoku to clear my mind using Sudoku Joy's random boards - which are available at all levels. I would highly recommend Sudoku Joy to anyone that likes to play Sudoku. The paid version lets you play unlimited games. The free version only lets you play one board per level per day, but is a great way to see if you like the feel of the game controls before you purchase the full version.

My favorite Sudoku app

When I first started learning Sudoku, i installed 4 apps on my phone, this one is the only one left, even after removing the other three and adding two others. I love the training mode, and how each difficulty adds new skills to learn. I have been trying the most difficult ones in the newspaper, and appreciate the hint system, which starts by telling you which area to look, then each successive hint gives slightly more detail and, if needed, a full explanation. Great app, please keep up the development!
