We know how it is. You worked hard for your 10:1 KDR, but sometimes, you just want to take five, relax and enjoy a quick game on your phone. Unfortunately, finding good games is anything but quick – most mobile gems end up buried under a mountain of trash. But like we said, we know how it is, so every month we shine a spotlight on a great diversion to get you through the work week.

This month our casual corner spotlight is being shone on Calculator: The Game by Simple Machine.

Now I know what you're thinking, "Calculator: The Game. You're joking, right?" At first yes, I clicked on this with the same thoughts as the rest of you wondering how this could pass for a game. Then, I stopped looking for other games because I like puzzles and this was actually a really good one. There is a caveat to this, however, and it's that you have to like numbers. Not necessarily math, but manipulating numbers in general. That's the basis of the game.

At its core, Calculator: The Game is a simple game of number manipulation. Math is finding an answer based off of a set of rules in the field. Calculator: The Game is a simple game of match using some basic arithmetic or some other means of adding a number to what you've created. That may not make the most sense due to me getting a little ahead of myself, but It'll make sense soon.

When you start Calculator: The Game you go through the basic tutorial where "Clicky," the calculator, gives you buttons that you can press and explains everything. During that tutorial, you'll get a few buttons and you have to match the number in the top right corner in the same number of moves, or less, as the number to the left of it. You do that and you win; it's incredibly simple to start out. As the levels progress, however, you're given different buttons that you can press.

As you can see in the screenshot above, you don't have a full calculator and you have to get the number 15 from /3, 1, 4=>5 and x2. What do those buttons do? You'll have to play to find out, but that's all you get to reach your goal. That's Calculator: The Game in a nutshell, but there really is a lot to how you go about playing this game and finishing each round. There are also hundreds of levels that they continually add to, not to mention the changing mechanics as you get deeper and deeper into it.

Overall, Calculator: The Game is a solid iOS and Android game. As we all know the market is oversaturated with puzzle games, so it's nice to see something new when you're checking things out. If you have any fascination with math, numbers, puzzles or all three this should be a worthwhile pickup for you. Download Calculator: The Game for free here on iOS and here on Android.
