Overview



Split Decisions is a word game played in a grid with twenty one split cells. Each cell presents you with a choice of 2 letters. To win the game, you need to select the correct letter in each split cell, spelling out the six hidden words.





The Form code



Most of the code used in this application is located within the main Form, as this game uses mainly graphical elements...

Public Class Form1
 
    Private wordGrid(4, 4) As String
    Private flipLetter(4, 4) As reveal
    Private answers(4, 4) As reveal
    Private r As New Random

        dgvGrid.Refresh()
    End Sub
 
End Class


The Game Class



There's just one Public Function used in this Class. This Function is used to create a new random game...

Public Class Game
    Private words() As String
    Private r As New Random
 
    Public Sub New()
        words = My.Resources.words05.Split(New String() {Environment.NewLine}, StringSplitOptions.RemoveEmptyEntries)
    End Sub
 
    Public Function createArray() As String(,)
        Dim wordGrid(4, 4) As String
 
        Do
            For y As Integer = 0 To 4 Step 2
                Dim word As String = words(r.Next(0, words.Count))
                For x As Integer = 0 To 4
                    wordGrid(x, y) = word(x).ToString
                Next
            Next
 
            For x As Integer = 0 To 4 Step 2
                Dim matches() As String = words.Where(Function(w) wordGrid(x, 0) = w(0).ToString And wordGrid(x, 2) = w(2).ToString And wordGrid(x, 4) = w(4).ToString).ToArray
                If matches.Count = 0 Then Continue Do
                Dim word As String = matches(r.Next(0, matches.Count))
                For y As Integer = 0 To 4
                    wordGrid(x, y) = word(y).ToString
                Next
            Next
            Exit Do
        Loop
 
        Return wordGrid
 
    End Function
 
End Class


Conclusion



This is another example of a simply implemented winforms game.
