Editors’ Notes

Classic puzzles for all difficulty levels and daily challenges with trophies.

Ad placement lousy


First, with a couple exceptions I really like the app. It has great features. For the challenge I like to play it with no extra tools or hints that I’ve made a wrong entry. At times I get to the end and there’s a problem I can’t undo easily so I just want to start over. I can’t see how to do that without “un-doing” every move, or selecting each square and hitting erase. Please add a button to clear the puzzle to start over.

My second concern is irritating enough to delete the app and find another game. On my IPhone 6s it’s the tight placement of the ad banner next to the number entry at the bottom of the screen. If I play with two hands inevitably I miss the number and hit the ad banner which takes me to another page. I understand the need for ads with a free game. But, that placement is so close that I mistakenly hit the ad many many times during a puzzle and I lose my place or thought process. It is maddening. I don’t even look at the ad, I get frustrated and immediately hit the button to return to sudoku. I’m glad you get the clicks for the advertising revenue but it feels like a setup with the layout so you get those clicks.

Please fix these. It would be a 5 Star review otherwise!

Great puzzles but intrusive ads


These puzzles are maddeningly more difficult than the last sudoku app I had on my phone. They make me feel like an utter moron for a long while before I finally crack them and feel like a superhero. The controls menu could be a little clearer (for example, “New Game” is misleading; I’d change it to “Options”), but overall the puzzle interface is intuitive and easy to use.

However, the incredibly long and unskippable ads for BS Candy Crush clones or Clash of Clans-style phone RPGs really dampen my joy. What’s worse, they play before they show my final time/score, which adds a certain dread that creeps up during the home stretch of finishing a game in anticipation of the annoyance. Because of this, I rarely play more than one game at a time. I would gladly pay for a pro version to make these intrusive between-game ads go away. The puzzles are my new favorite daily challenge, but the annoying ads keep the app from five stars.
