The object of the game is to solve a system of equations with unknowns represented by fruits. The player is given the column sums and row sums, and from there he must determine the value of each fruit. The game difficulty can be changed, and it ranges from solving 3x3 fruit equations, all the way up to 9x9 fruit grids.
