Study the examples, then complete the answer grid.
In this puzzle, you are given two examples of a transformation applied to a grid of coloured cells. Your task is to determine the rule governing the transformation and apply it to the answer grid.
Each example consists of a "before" grid and an "after" grid. The "before" grid shows the initial configuration of coloured cells, while the "after" grid shows the result of applying the transformation.
To solve the puzzle, carefully analyze the changes between the "before" and "after" grids in both examples. Look for how the "before" grid has been transformed. Once you think you've identified the rule, apply it to the "before" grid in the answer row to fill in the "after" grid.
Use the colour picker to choose which colours to use, and click a cell in the "after" grid to fill it. When you're ready, click the "Check" button to see if your answer is correct!
Good luck, and have fun solving the Arc Puzzle!
