This game is extremely relaxing to me, and it is often what I like to play at the end of the day. The music definitely adds to this. But, feel free to turn sound off if that distracts you. Math is the type of thing that always has right and wrong answers. I used to tell my students that, History is filled with wars, politics, and conflicts, but Math just exists. It’s beautifully simple. And, there is no conflict. Most likely you enjoy Math as well, or you wouldn’t be playing this game. But, seeing the lack of guides yet, since the game is new, I thought I’d share a few simple ways of thinking through this rather simple game. I hope you like it as much as I do. I have finished the game and all achievements, and doing so won't take you but a few hours of game play. The bulk of my guide is in the “one method” I’ve used throughout the game, that I explain in detail below.

The name Two Digits seems to be taken from the idea that all the numbers on the board are in the range of two digit numbers between the numbers ten and ninety-nine. The significance of this range escapes me, other than the fact that it may be considered slightly more difficult. Of course, if you are following the leveled path, the game is in effect teaching you the correct method to play it as you proceed through the lower levels. And, the lower levels mix in a variety of one digit numbers. The more one digit numbers you have available, the easier it is to build new numbers to match an existing number on the board, and all done in your head.

Sums- What we call the numbers in the bottom left and right of the screen. These sums accumulate as you add numbers to them from the board.

Green, Orange, & Teal- The 3 colors as I see them on my screen, for lack of a more exact color name for these unusual colors.

Teal –The origin/start color for all numbers on the board.
Green Slot – The sum slot on the bottom left of the screen.
Orange Slot – The sum slot on the bottom right of the screen.

First, you can check the total of all the numbers on the board before beginning by changing them all to one color. Then it’s easy to hit reset to put them all back. They will always reappear in the same spot, so no worry. This is helpful for two reasons.
-It lets you know if it is possible to form even numbers easily. Just a little more info.
-Also, if you are looking for the achievement for using the whole board, you will most likely not
be able to do so if the board total is odd. Look for board totals that are even for this
achievement.

Second, you can sequence the numbers on the board quickly in your head.
-This helps you “get to know” the numbers you are working with on an individual board.
-It also helps you determine the spacing between pairs of numbers.
-Though the first recon method may be skipped with no problem, this second step is probably
critical, especially late game. If you skip it, you will find yourself staring at a board for a long
time needlessly.

The one method that I found myself using early is placing numbers that are a set amount apart and then finding a second set of numbers that are equally distant to counterbalance the pair. This method continues to work late game.
For example: You can place 21 in the green slot & 22 in the orange slot, then balance them with 8 in the green slot & 7 in the orange slot. 21+8=29 and 22+7=29

The 2 pictured examples below are from the same game board. The green and orange slots contain sums of 80 & 70, which are 10 apart in value. Meanwhile, you can see in the 2nd shot, the sums of 83 & 93 are also 10 apart in value. Combining the 93 with the 80 in the green slot, and the 83 with the 70 in the orange slot will cause them to counter balance. Giving you equal sums.

This method always works when you can find two pairs of equidistant numbers.
Most boards will have multiple such pairs that are one or two apart in value.
I even found a board with two pairs of numbers that were 20 apart in value. These patterns are usually easily noticed because of the last digit of each number being the same.
This can be extended to work with 3 & 4 numbers, so that you are effectively whittling away at larger differences in the two sides of the board.

A second method I find works frequently is finding 2, or 3, or 4 numbers that add up to one other number already on the board.
This works easiest in the early game, and would get clumsy if it weren’t for the fact that the game keeps a running total for you on each side in the slots.
In mid game, it remains workable if you be sure to keep your eye on the largest and smallest numbers on the board. Two of the smaller numbers will often add up to one or two of the largest numbers.

Pictured below, the sum in the green slot equals 48, and 48 is also on the board.

In the second screenshot, the sum in the green slot equals 90, and 90 appears on the board as well.

Balancing sides becomes slightly trickier when dealing with a board full of only odd numbers.
-Keep it simple by remembering that two odd numbers add up to an even number.
-So, you will most likely have to add 3 numbers to equal 1 other number on the board.
-Or, adding two numbers and two numbers will get you a matching pair of even sums.

A note about the random mode: While the leveled game progresses in an orderly fashion within a set range of numbers, the random mode will allow you to set the range. So, it’s not really what I would call random. It just provides an option to choose. This mode does give you the chance to take what you’ve acquired in the leveled mode and strengthen it, or expand it. I would say it is easier to note the patterns by following the leveled progression first, before venturing into the random mode.

These methods worked for me. It really is a simply constructed Maths puzzle. If you like this sort of game, I’ve recently discovered Energy Balance, which is also a Math puzzler. Only the whole structure is different. Energy Balance is more algebraic in nature and may bring tears at times. But, the glee is compounded when finding an answer. On the other hand, Two Digits is an easily learned exercise in arithmetic. And, it is very relaxing, yet good exercise for the brain. Feel free to leave any tips you have found in the comments and I will update this guide as more info and ideas are available.

Thanks for reading my guide.
