Number Master: Run and merge

Once you've played 5 levels, you've played them all. I maxed out all upgrades early and nothing changed. I figured if I played to level 100, it may unlock further upgrades. Nothing changed. I might've even given this a 2 star, but some level designs are made in a way that at the beginning of the level there are numbers too high for you to touch, meaning you HAVE to pass them. Not to mention, after 100 LEVELS, I've never reached 6k, let alone 777x. It's a huge time waster, just in the worse way.

It's a fun free game with a normal amount of ads. The downside for me is that there's no home screen, so the only way to get a second chance on the same level is to die in purpose or close the app before it finishes. Also, each level has a different "perfect score," but there's no way of knowing what that is. For instance, a great run on one level might be 600, and on another level you might easily get 2,000. Other than that, this game is great for passing the time during mundane activities.

-Ad abuse: (note: game unplayable without wifi) The ads are long and take 3 taps to get out of, The levels are 10 sec. or less and you get an ad after each one. I would understand if the game was great but it's not up to that standard yet. -Lack of substance: There is not much to the game. It's just + & - #'s There are no "upgrades" or added puzzles. -Haptic/Sound/Settings: no icon to indicate where those things are. Haptic reduces performance of game.
