Five poker chips are arranged in a row as shown in the top figure below. The challenge is to move them so that they are arranged like the lower figure, in the fewest possible moves.
- The chips stay in a horizontal line with each other between moves. Gaps are allowed, except at the beginning and ending arrangements.
- You must move two chips at a time, and the pairs have to be touching and be different colors.
- The pairs must keep their orientation: the left stays on the left, and the right stays on the right.
The solution to this puzzle can be converted into a discount code, good for 15% off any reservation at Trapdoor Escape Rooms, by combining the digits in each pair (read left to right) into a number, and separating each move with a dash “-“.
For example, if your first move shifted 2,3 to the right of 5, You’d have “23”. If you then moved 5,2 back to the left of 1, you’d have “23-52”. Keep building the code until you’ve got a solution.
