Everyone should check out these games if they enjoy puzzle games! 👍🏼

Stanley Lam's games are some of the very best I have found on the AppStore! I left my review on his Samurai Sudoku game because I really like that type of Sudoku but ALL of them are awesome and well done! He has a mix of different kinds of games, Sudoku included, to play. He lets you try them all for free and then just a small fee unlocks the whole game if you like it. I have almost all of his games. I am so glad I found his games on the AppStore!

Nice variation on Sudoku

Once I found the auto fill for notes and the double tap to convert a single remaining note to an entry, it got a lot easier to focus on the strategy. The anti-diagonal version is a really nice twist.

Update 2 years later...

The sheer variety of board types that have been added since I first discovered this app is lovely. It gives the brain a different mental challenge to figure out the nuances of a new game shape or rules in addition to the usual Sudoku puzzle.

This is the only Sudoku app that tempts me back from my preferred Killer Sudoku.

Locked up

I would give this app five stars but it locks up when watching the “required“ videos. I like the games but I cannot find how to purchase it so I do not have to put up with the ads for more games. Now it appears to be locked permanently. I can try deleting it and reinstalling it again. But if this is going to be a recurring problem, it is not worth it. I regret this because it is well designed and laid out.
