UPDATE: More variety needed

The game is fun until you get good at it, and then almost ALL of the daily challenges become “Hard” or “Expert”, with over half being Expert. These games start with NO numbers so you are forced to watch ads to get Hints (numbers) to put in the puzzle. Otherwise, the daily game is impossible. Here’s a novel idea - how about keeping the same or SLIGHTLY modified diversity of game difficulties in all months? My response to all the Expert games is to just not do them. I refuse to watch 10-20 ads just to finish one game. And that means less activity and less ads that I view. So it actually does the opposite of the intended result - I view less ads so the game gets less revenue. Change the daily games back to varied difficulty and I’ll play more, see more of the usual ads, and give a higher rating; until then, I’m playing less and the rating remains at one star. Thanks for listening.

UPDATE: The developer responded very quickly and explained the daily challenge randomization. I appreciate their reply and suggestions. Therefore, I have changed my rating to 4 stars. Still need to try their suggestions!

Killer Sudoku

I loved this game — until today. Since this is a free game, I expect and accept ads. However, it’s escalating way beyond okay. At first the ads were between every two or three games, then after every game. Recently there has been a mid-game ad in every game, plus at the end of each. Today there has been two and three mid-game ads and the between game ads. The ads are around every two minutes, but often less. It throws off the pace of the game in several ways. I’ll be adding up a larger block to decide what I need to put in, but after the ad, I have to recount. Since I don’t always come back in the same square I thought I was in, I have to be sure not to type the number I had been typing because I’ll get an error and have to watch another ad to “buy” another chance. Instead of being relaxing and/or challenging, today was frustrating and irritating. I finally quit and won’t try again today. If this greed fest continues, I’ll be looking for a new game (and NOT your regular Sudoku — it “caught” the same disease today)

Hi! Thanks for sharing your opinion! We're sorry that you remained unsatisfied with our app. We understand your concerns, but we need ads to support and improve the game to stay free for everyone. Please note that you can get rid of ads: press the gear sign in the upper right corner and press Remove ads. Also, you can disable the mistakes limit in Settings to avoid extra watching of ads: open the app, tap "Gear," select Settings, and turn the "Mistakes Limit" toggle off.

Hard to see

Interface is easy to use. Preset numbers are black and numbers you pencil in are dark blue. Not enough contrast to easily discern which are pre-existing and which you wrote in. I tried to see if there was a way to change the font color... not there. Also magnifying glass doesn’t help me see the number total in the corner of the cages. It’s super super small. I’ve also mistaken some cage groups when they extend over to another 3x3. It would be helpful if the dotted line was in red or another contrasting color.
Also when I initially started playing, I accidentally hit a wrong number- one that was not my intended target. Wasted an error bc of mistyping. There should be some way for it not to count if it is corrected immediately. I ended up turning off the error count in settings.
Fix these and the game would be perfect.
Disclaimer- This is my first killer sudoku. I do enjoy it. I’m not sure if others address the above issues or if they’re all the same.
