Bit Addiction is an adaptation of the popular "Picross" or "Nonogram" Japanese puzzle form; "Picross" is a merging of the words "picture" and "crossword." In a nonogram puzzle you are given numeric clues that tell you how many blocks in each row/column of a grid are filled in. Your goal is to find out which ones are filled in to complete the puzzle and unlock the hidden picture. This guide will show you the basics of playing the game so you can go forth and solve puzzles on your own!

NOTE: This beginner's guide will guide you through puzzles using examples from the "Normal" (10 by 10 grid) difficulty. "Easy" puzzles (5 by 5 grid) make for a difficult to understand guide despite their simplicity.

For this tutorial we will be using the puzzle "Pineapple" which you may access here:

The Basics: Full Rows
Two "freebies" you want to keep an eye out for are rows that are completely blank and rows that are completely full. This puzzle has one of each. Note the "10" column and the column without a hint.

The 10 column is full, the "0" is empty, fill these in now.

You might be wondering what multiple clues mean (e.g. "2, 1, 1, 1, 1"). These clues mean that there are multiple groups of blocks in a row that are separated by at least one blank spot. A clue of "1, 1" will NEVER be two blocks side by side otherwise the clue would be simply "2." The smallest amount of space "1, 1" can occupy is three squares (one filled in, then a blank, then another filled square).

Advanced: Add-Up Rows
Another "freebie" that you can search for are clues that add up to 5, 10, or 15 depending on the size of the grid. When you add up the clues remember to add 1 extra square for a blank. Let's take the "2, 1, 1, 1, 1" clue we saw earlier.

2 + 1 + 1 + 1 + 1 = 6.

6 + 1 + 1 + 1 + 1 = 10. Each "1" is the minimum blank space between each section of clues.

Because the row adds up to 10 you can fill in the entire row without fear of making a mistake, like so:

The Basics: Partially Solved Rows
Now look at our table. You might be confused on where to go with the rest of the clues. Let's start from the top row of "3, 3". Where would the other two blocks go to solve this row? You would NOT fill in the block between the two sections of solved squares, but do you know why? If you put a block there then you'd make a row of 5 and "5" is not a clue for that row. Obviously, that center square has to be blank, so you can place an X in it.

By marking that square with an X you've uncovered the "border" where you can see where each group of 3 starts and ends. To complete this row you need to add one square at both the beginning of the first group and the end of the second, like so:

Now let's focus on the opposite. Take a look at the rows marked with clues "5" and "7". We had to put an X in the middle of the row for "3, 3" because otherwise it would make the row too long (and would be a mistake). In this case we need to fill these center squares in because since we only have one clue a piece for these rows there will not be more than one group of blocks filled in, it MUST be one straight line of 5 or 7, so fill these blocks in… and also take note that you've now solved the "5" rows!

The Basics: Using Your Surroundings
Remember when you marked the "0" column full of X's? This effectively made the grid only nine squares wide; look at the row clues: we have a "9!" Even though the grid is 10 by 10 it is technically only 10 by 9 because of the empty row. We do not need to worry about mistakes because the "9" row will be completely filled in, so go ahead and do that now.

Advanced: Size Matters!
When you get pretty far into solving a puzzle you'll start to see "gaps" in the grid where you haven't completed anything. Let's take a look at the "2, 5" columns. Somewhere in this grid is a place where five blocks in a row are going to be filled in, can you see where? There is an empty space in the grid five blocks tall, this is the ONLY place where you can fit five simultaneous blocks in a row. These blocks can go nowhere else, so you know for sure they will fit here. Go ahead and fill these in, and also take note that you've solved both of these rows!

The Basics: Pay Attention!
Check out where we are now, by solving the "2, 5" columns you've also solved the rows with the clues "7" and "1, 1, 1, 1" at the same time! Go ahead, count up the squares, those rows are 100% done. When you solve other rows make sure to recount sections you may be stuck on; solving rows elsewhere in the puzzle can give you clues to other sections or even solve them outright! Mark all of the empty spaces in these rows with an X, we're almost there!

You're On Your Own
We're down to the last row of the puzzle after doing nothing more than starting with the rows that we knew would be completely full or empty and then working from there to figure out the rest of the puzzle. There's one row left, and there's multiple clues that you can use to solve it. Yes, it's pretty obvious where the last few blocks go, but don't just rush in there, make sure you look around and understand WHY the blocks go there!

For example, check the columns with the clue of "2." At this point you have the first block filled in. This is an important block to have filled in because it tells you exactly where the blocks will start AND how many. Let's say the clue was "10," if you had the first block filled in you know for a fact you could fill in the next 9 blocks without mistake. In this case it's only a 2 so you know the next immediate square will be occupied.

Another thing to look at is the middle of the unsolved "1, 3, 1" row where the "3" goes. Not only do you have the beginning AND ending squares filled in you can also use the clues around you to know that you can only fit 3 squares in a row in a space of 3 or more, and with a 3 square gap this would fit nicely in there. You can either look at this part as "you can only fit 3 blocks into a space of 3 or more" OR "with a clue of '3' you have to have 3 blocks in a row so the center square must be filled in".

But of course, since it's the last row the solution is pretty obvious. Once you place the last squares down it will come to life.

It's a pineapple! But I guess the name of the puzzle gave that away.

Now you're ready to try out the other puzzles we have! I suggest starting with the Easy 5 by 5 grids if you're still a little unsure about how the game works. You'll be able to reference back to this guide if you ever get stuck. Remember, though, this the most important fact about this game: you must always have at least one empty block between clues!!!
