4 + 2 - 3 + 1 - 3 + 2 - 4 + 1 = 0

Zeroes is a mathematical puzzle game that is available for both Windows PC and Phones where you shift numbered blocks around to create equations where the sum is zero.

The layout of the game is simple, but by no means should that mean the game itself is a pushover. It does have a casual pace with no game clock or score. All you have to do is structure equations until you have zeroes across the board to advance to the next level of play. While Zeroes isn't an overly complicated game to pick up and play, the mathematical challenges can be rather perplexing. After spending time with the Windows Phone version of Zeroes, we found the game to be slightly addictive and an entertaining way to pass the time.

The primary menu for Zeroes is simply laid out with options to jump into gameplay, visit the game's various social networks and buttons to mute the sound/music.

Zeroes has one hundred, progressively unlocked puzzles with the first few levels being more tutorial in nature than challenging. Each level will have a series of numbered pegs and blocks. Your goal is to connect the pegs with the blocks to create equations where each sum is zero. Just tap/hold on a block and slide it into place to connect the dots. The numbers will form an equation and it may take a chain of connections to get everything zeroed out.

For example, you may have a block with a -4 that can be used to connect a pair of 4 pegs, changing both pegs to zero.

While the first sixty levels of play involve equations that deal with addition and subtraction variables that are headscratchers in their own right, the game also includes 20 levels that have powers and roots variables and another 20 levels that have modulo variables. If the first sixty levels do not kick your butt, the last forty should.

The pace of gameplay is casual with no gaming timer or score to reach. You just need to make sure all the pegs end up at zero after plugging in the various blocks. If you misplace a block, simply tap and drag it out of play.

Overall, Zeroes is a fun game that is mentally challenging. The mechanics are simple and the puzzles difficult but in a fun way. The challenge keeps the game interesting, but not to the point where gameplay becomes frustrating.

For me, gameplay was a little overwhelming at first, but as you start connecting numbered pegs and seeing the results, the flow of the game begins to fall into place. Once you get the flow of the game, you can concentrate more on the correct placement and solving the puzzles.

All in all, if you like puzzle games, Zeroes is worth checking out. It is a free gaming title that is available for Windows 10 PC and Mobile.
