y is making one so complexated ,

It’s good but could be better.

The game is fun and is a nice calm game to play while your waiting for someone/thing or trying to relax. That being said it’s ok to have adds but there to many. It takes away from the actual game play. The game is good but u have to watch 1to2 adds everytime you mess up or pass a level. You spend more time watching adds than actually playing the game.

Very fun and easy but...

I really do enjoy this game. It takes a little strategy but not much thought which is pretty nice. The part that I have an issue with is if I need a max or min card and watch an ad, it should automatically apply the card. It’s not like the cards can be saved and used on a different level so just use the card automatically after watching the ad. The way my mind sees it, I click on a card to use it. When I click on the min or max card to watch an ad, that’s me selecting the card. So I’ve had multiple times where I lose the level because of that and I select another card without selecting the min or max card again. Give a setting for an option to have it automatically added or manually add it. I have no problem with the ad situation like many others have. Their frustration comes with they don’t understand the difference from a 30 second ad and a 5 second ad that you have to hit the fast forward button (only on some).

Not very amusing

I downloaded this after seeing an ad about it, and it look like something up my alley. While it was downloading, I looked at the ratings (4ish) and was expecting it to be an awesome app that I was going to be addicting to. Within thirty seconds of download, I was on level 2. I figured out how to turn the vibration off which I disliked, so then I was thinking that I was going to start enjoying it then. Now, I was onto the next level (3), and I was sitting there staring at the app, contemplating what I was going to do, but I was starting to fade off in liking at the end of the first round. I ended up deleting the app after 45 seconds of downloading. I would recommend not to download this app. I can’t say that it gets worse later or better in the future of playing, but at this time, I wouldn’t downland this app since it is very very very boring. Don’t download!
