ah the fastest way to earn the first badge is to find a board with 2 high numbers. This way you MUST use certain ones and can then lock the row. Or use rows with very low numbers so that you can lock out any higher number. Please + to keep at top.

"The puzzle is randomly generated so you'll never get bored of playing"; actually, guess-and-check all over an 8x8 board gets boring real quick.

The 8x8 2-4 level is incredibly difficult, and required a lot of guessing and going around in circles for me to figure out. My strategy was to write down which numbers must be activated and just guess with the ones that could be either on or off.

This is actually not a good puzzle because the solution is NOT unique. Tested and proven myself. There are multiple solutions to one puzzle. So even if you were to guess, you have to calculate almost ALL the steps in advance TO THE VERY END of the puzzle to know if your guess is right or wrong. And this is assuming there is only one branch where both paths can be correct. If there were two, you would have to make even more calculations, where one is already impossible for the human brain. Furthermore, there is no way to mark guesses. This is a good idea for a puzzle game but poorly implemented puzzle generation. If you are going to make a puzzle this complicated, MAKE SURE THE SOLUTION IS UNIQUE.

I had to make a note to get the 8x8 2-4 solved, but then it was no problem. If someone needs help just write a PM :-)

At first I thought this was really hard. But then I realized the trick is to first eliminate the numbers that can't add up to the outside numbers with any combination. (I.E. in the first puzzle, 4 can't add with 2 or 3 to get 5) And the rest came pretty naturally.

This is a fun little puzzle game, but oftentimes you truly do need to guess. It becomes very obvious when you get a 2-4 puzzle that ends with a square of four 2s. You can win by removing two diagonally across from each other, but it doesn't matter which two you remove. So yeah, sometimes there's more than one answer, don't let others tell you otherwise. It's just that they have yet to run into one such puzzle.

"you shouldn't need to guess" says people who haven't been trying to do puzzle 81 on endless mode for two months. I'll get there in the end, but, you know... stop

As others have said, locking helps. Also, there is no need to *guess*, even on the 8x8 modes. You can slowly piece it together with logic. Start with rows where you can confirm or eliminate numbers easily. e.g. if a row needs 30, but with ALL numbers active, is at 35, then you know that any number greater than 5 MUST be in the answer. You can lock those as confirmed. You can also lock any number where it would be impossible to get the answer if there are no other numbers that could pair with it. e.g. in the above example, if there is a 4, but no 1's, then the 4 MUST be in the answer as it would be impossible to remove the 4 without breaking it.

Note: 8x8 2-4 level may have more than one answer.(I had did a puzzle that contains at least 2 available answers.) It is better if you use excel to do it.

Welcome to my exhaustive list of favorite games (all both of them). This is actually more fun than kakuro, which I once thought was the only math-based game I'd ever enjoy. 2-4 is a bit aggravating, granted, but the other modes make this a hands-down favorite. If I were to change anything, it'd be allowing me to pick colors for circles, backgrounds, and such, just because I want to try a Joker-themed set-up.

took me a bit to click. it was super challenging until I red I could lock numbers. then I started looking at it sort of like Sudoku in my mind. not same rule sets but just the way my brain clicks with shit like this. came for the achievements. Stayed for the chill =) well done

That moment when you find a logically solvable 8x8 2-4 :D (It had 6 and 8 in first wow and 8th column, so its was close to a 7x7). Great game, nice concept!

to me, this is a great spinoff to Picacross, with great zen-like music but more math. (granted they are two completely different games but they both play well and similar to each other.)

Fantastic presentation on a puzzle game that, while I'm almost certain I've seen it before, feels pleasantly fresh. The only complaint I have I managed to find a workaround for while writing this comment, which is that cinema mode doesn't work properly unless you right click and select show all. A couple of recommendations I have is that it would be nice with the option to always show the sum next to all the answer boxes and to add a keyboard shortcut like shift+click as an alternative to lock numbers instead of holding.

Just finished my third "endless" level, and I can say with certainty, whatever algorithm makes those ones, it is NOT guaranteed to be logical to only one solution. The one I just finished had at least four possible solutions. To wit: (1,1); (1,2); (6,1); (6,2) were all 4's. I greyed out (1,1) and (6,2), but I could just as easily have greyed out (1,2) and (6,1) instead.

Pretty genius game. Like sudoku, there's a way to easily solve most. Start with the shortest path, largest numbers. Count up the total of the numbers in that row. See how much you need to subtract, and which combinations of numbers make that subtraction possible. Also, for the smallest numbers, you can just remove any number that's larger than the row's supposed total.

I'd love to have it show the current total of each row of lit numbers, and the difference between that and the target.

Some of the puzzles have several solutions, but with few numbers available through deduction. You need to solve it by trial and error when 80% of the numbers are still remaining: ragequitting, here I come....

Ah! I see it's the locked vs. unlocked. I don't know why I didn't see that before. I've been playing this for a while!

I haven't quite figured out what the wider vs. thinner line around the eliminated numbers means. I assume one indicates a wrong choice, but I haven't figure it out and I'm in the middle of a puzzle and don't want to quit it to test the theory on an easier puzzle!
