  • Too many ads

    By *******438966%%%
    It’s a fun game but the ads are literally so ridiculous that I deleted the game. No matter if you choose “ad for 5X the diamonds” or not…. You still have to watch an ad. It’s so annoying.
  • Excessive ads

    By Barb-Simplified
    I wanted to like this game. I’ve seen the ads for it. But I started playing … played one game 15 seconds had a long ad. Came back played another game had a long ad. I don’t think this would be fun in the long-term to watch all these ads more than playing the game.
  • Mismatch between developers

    By 654evan7652588
    I downloaded this game thinking it would be okay because it was by Zynga games, but this doesn’t feel like a Zynga game. It feels like a Playrix game instead. The amount of ads doesn’t match the number of ads in the Harry Potter match-3 game by this developer, which has ads but not very many. It matches the amount of ads in the Playrix game Pull the Pin which has ads after every round and in order to claim anything gained through progress. Please reduce the amount of ads in this game to a level similar to the level of ads in your other games.
  • Ads and Freezing up

    By Ahayle1
    I love the game but having ads every level that one can not get out of and the ad causing the game to freeze up(banner ads) just does not interest me into purchasing an ad free game because I would be afraid it would still have ads and freezing up. Another game that will be deleted, it is a shame.
  • Love it

    Pretty fun I shall now recite a poem. Roses are red violets are green I like this game. It’s better than beans
  • Ads after every round

    By Jawn M
    I’ll complete a level in less than a minute then An ad, I’ll patiently wait and then go through the process of clicking through all the phases of the ad till next round, then I’ll play my second round complete that in no time, then another very tedious and long ad. Not a fan, However, the game is good idea and I like the style of the game. It’s just you can’t even play the game cause of ever add lurking behind every corner.
  • Deleted - Ad level is insane

    By Jpmcftghbmo
    I remembered this as an okay game but I hadn’t played it in a while. Just updated & reloaded it. I got three ads DURING my first game. There won’t be a second.
  • Too many adds.

    By UnusableSurveyApp
    You spend more time watching adds than playing the game. Deleting this app.
  • In what world is this fun?

    By Sup3rnatural666
    This game is just boring, it’s literally elementary school math. Plus, what’s the point of having the choice of an ad that gives you a reward and a choice of skipping the ad and the reward if either choice makes you watch an ad anyway!? This is literally the least interesting game I’ve ever played
