Tough Measures wants to know: Can you Rule the Ruler? This spatial reasoning puzzle requires you to position the two rulers so they both ft perfectly on the grid together without any parts hanging off. The rulers will cross over each other at some points, either on top or below. Each ruler folds and stretches out on multiple axes. More complicated than it appears!
