The main characteristic of the Quad Quandary challenge is defined by its field, which is a 12' by 12' square divided into four equal quadrants. Each alliance (red and blue) are given two quadrants, of their color, on opposite sides of the field. The field is split using two diagonal lines. The challenge uses rings (placed on the opposite color's quadrants and mixed on the quadrant division line) and two different kinds of posts — two 18 inches (457 mm) high posts (atop the single goals), and two 24 inches (610 mm) posts connected by a 60 inches (1,524 mm) bar, which rest atop the paired goals. The bar rests 9 inches (229 mm) off the ground but during the match, can be raised up to 15 inches (381 mm). The rings may also be placed on a 3.5 inches (89 mm) high base, known as a goal (single or paired), that holds the posts. The goals are on casters and thus can be moved. There are also four, 20 square inches (129 cm²) low goals centered along the edges. The rings used have a 3 inches (76 mm) inner diameter and are Convert|1|in|0}} thick. There are 50 rings total; 25 for red and 25 for blue. There are 44 total rings on the field, and three available to each alliance to load on their robot before the match starts.
