| This puzzle consists of a grid (normally 35 by 35 squares). For each row or column you are given a list of one or more numbers (left and top). |
 |
| These numbers identify the length of blocks which are contained within the relevant row or column but not their position. |
 |
| For example, the clue "2 23" means that this row or column contains 2 seperate blocks, one which is 2 squares in length and the other 23 squares in length. |
