Ads

There is nothing more frustrating than ads popping up while doing the daily challenge. I understand having an ad before beginning or after completing the puzzle, but ads while working a puzzle made me delete the app.

Love it but phone gets super hot

Love the game but my phone gets super hot every time I play it. It drains the battery so much too. I wonder if something else is running in the background.

ADS EVERY COUPLE OF MOVES SUCK!!!!!

I like the game HATE the constant bombardment of ads!!! In the middle of when you’ve looked at the number set and decided what needs to be picked and deleted after one or two moves you get an encouraging phrase like GREAT JOB!!! Then the interruption of an ad!!! Completely screwing up your chain of thought!!! STOP THE CONSTANT MID-GAME INTERRUPTION OF THE ADS!!!
