User reviews

Ads block game

I try to start a game, but an ad pops up telling me I must update before playing. The ad takes you to a different soduko game by a different developer. I waited 4 minutes but still couldn’t close the ad. You need to get rid of competitor ads like this.

Ads Aplenty

Ads for games are much too long and no way to exit after a few seconds... not worth it

Difficulty level - Ha!

Need to redo how they calculate difficulty level. Most are way harder than they say.

Ad roadblock

Can’t get into the game! Full page ads that have no x or decline option. Only “open store”.

Better than most

I find I like the options and clarity on this game. At least the adds don’t come until you finish the game.
