Tally Board is a highly addictive game in the puzzle niche. Built with math's principles in mind, this title challenges players to find a way of clearing the numbers' board using the least amount of moves. The game is very challenging even at the lowest difficulty levels, challenging players to resort to smart thinking and use their best math solving skills. Tally Board can also be extremely helpful for all those who need to exercise math, but it's also a great way of spending free time. This game is compatible with all devices running iOS 7.1 and above (iPhone 5, 5S, iPad 2, 3, 4, etc.). Here is how it is played:

Choose A Difficulty Level
After installing the game, players are required to choose a difficulty level for their future games. This can be either Easy, Medium or Hard. However, it's to be noted that the game is quite challenging even at the Easy level, so it's not recommended to opt for the Hard unless you are a master at math games such as 2048 or Sudoku.

Go Through The Tutorial or Start Playing Right Away
Once the difficulty level is set, players can opt to either go through the tutorial in order to learn the key tricks for mastering this game or start playing right away. The tutorial includes some great information on how the game is played and also enables gamers to practice swapping tiles a little before the actual gameplay. However, even in its absence, learning game controls is not a difficult to task. Basically what everyone is required to do is combine 2 numbers which form the next one (3rd) through addition or multiplication. For example, if the number 5, 3 and 8 are on the table in a straight line, anyone can combine 5 and 3 into one because 5 + 3 = 8. Another example: if the table features 3, 3 and 9 in a straight line, 3 and 3 can be combined into one because 3 x 3 = 9.

Combine 3 or 4 Numbers
Even 3 and 4 numbers in a row can adhere to this principle. So if there are following numbers: 4, 3, 9 and 16. 4, 3 and 9 can be combined into one because 4 + 3 + 9 = 16. Once this principle is fully understood, the game becomes a little easier to play, yet it' still challenging as there are plenty of numbers on the chalkboard.

Never Lose As In Solitaire
Some may be aware of the Solitaire principle in which some games end halfway as there are no more numbers available. In such situations players need to start a new game, but this is not the case in Tally Board. This game is very well thought, so if there are no more numbers to combine, players only have to swipe in one direction in order for an additional number to appear.

Swiping Too Many Times Is Not Allowed
Some players may try to cheat the game by swiping too many times randomly and hoping to hit the right combinations. However, this approach is a surefire way to lose. If one swipes too many times randomly, then the chalkboard will quickly fill up and the player will lose. This option makes the game uncheatable and more challenging.

3 Available Power-ups
Those having troubles in completing a certain level can also resort to the available power-ups. These are: Hint (indicate a suitable combination), Free Move (move a tile anywhere on the board) and Swap Tiles (exchange numbers between them; anywhere on the board). These power-ups are great for making more combinations, but they come in a limited number.

Clean Graphics, Cool Sound Effects
At last but not least, the game features some very well thought graphics which tend to resemble real numbers drawn on a chalkboard. These are accompanied by cool sound effects which entice the player into thinking and relaxing at the same time.

Conclusion
Tally Board is a challenging puzzle game which is great for killing free time or for competing with friends. It comes with a clean interface and a smart gameplay, which will make anyone to think well before making a move. The game can be downloaded from App Store for \$0.99 only.
