1. Shade some empty cells to create a single connected wall.

2. Numbers in a cell indicate the length of consecutive shaded blocks in the neighboring cells.

3. If there is more than one number in a cell, then there must be at least one unshaded cell between the shaded cell groups.

4. The shaded cells cannot form a 2X2 square anywhere in the grid.

5. Any "?" represent any number greater than 0. Different "?"s in a particular cell may or may not be the same.

6. Cells with numbers cannot be shaded.

- For shading use one of DG (Dark Grey), GR (Grey), LG (Light Grey) or BL (Black) colors (Submit button will only detect these colors as answer).
- Other colors can be used for auxiliary marking of un-shaded cells.
- Tip : On laptops -> Right click gives you green color. You can also use numbers to quickly switch between colors.

A is determined by player's rank on that day. The table below demostrates the link between rank and A. | B is puzzle difficulty indicator. Players solving all 16 puzzles will always get 1600 points as B. B for each puzzle will be calculated based on the following formula after the official time for the puzzle is over. B for Nth puzzle = 1600 * (Avg of Top 10 players's time of Nth puzzle) / [ Sum of (Avg of Top 10 players's time of all puzzles) ] | First 100 players to submit the puzzle will get C as 100 to 1 |
