You play as Rob the chicken. The goal: move the blocks around so that the expected results on each column and row match the actual results by either adding, multiplying, or dividing  every block in that row or column. It's a little hard to explain, but once you play around with it a bit, it becomes more obvious. Currently has a pretty crappy level editor and 3 built in levels. there are some bugs, but everything seems to run pretty smoothly.

made under the color and resolution restrictions of the NES.
