Help the reindeer to get to Santa\u2019s sleigh. He can only move to the next tile if it is different from the one he is on<\/strong>.<\/p>\n

He can only ask the elf once<\/strong> to lay down a red carpet for him to move to the next tile if he gets stuck. Drag and place the red carpet<\/strong> wherever you think it is needed.<\/p>\n

\"\"<\/p>\n<\/div>

Here is an example.<\/p>\n

There are 2 blue tiles next to each other. The reindeer cannot go any further. So he asks the elf to put the carpet on the first blue tile to cover it. Now he can join Santa\u2019s sleigh.<\/p>\n

Use the \u2018Check\u2019 button to verify your answer (where to place the red carpet). Use the blue arrows to try different puzzles.<\/p>\n
