Field notes
The page explains a staged operator set: levels 1–4 use addition and subtraction, multiplication and division begin at level 5, and powers and roots arrive at level 10. Players may build a short expression for a quick clear or a longer one to clear more at once; mistakes carry no penalty. The stated play area is 360 × 480, and reaching 100% occupancy ends the run.
