  We begin by considering the expectations of the creators of VisiCalc, the
first spreadsheet. The emphasis is on the nature of the spreadsheet grid. The
grid is taken as a presentational method for showing a solution to a Sudoku
puzzle. We consider methods or approaches for the solution. We look at the
relationship between this model and academic papers on the methods for
describing and categorising end-user models generally. We consider whether the
type of model described here should be categorised separately. The complexity
of the model is reviewed in the context of commendations to minimise overly
sophisticated presentational constructs and formulae.
