Visual Basic Jigsaw Puzzle

Create a classic puzzle game with drag-and-drop functionality using VB6


Introduction to Jigsaw Puzzle Game

Jigsaw puzzles are classic games where players reassemble pieces of a picture that have been cut into interlocking pieces and jumbled up. This Visual Basic 6 implementation demonstrates how to create a simple 3x3 jigsaw puzzle with drag-and-drop functionality.

How It Works

Our VB6 puzzle allows you to drag and drop pieces into what you believe are the correct positions. The program validates each move - if correct, the piece stays; if incorrect, it returns to its original position.

Key Features

  • Drag-and-drop puzzle pieces
  • Position validation logic
  • Visual feedback for correct/incorrect moves
  • Simple 3x3 grid interface
  • VB6 sample code for learning

Game Interface

The puzzle interface consists of a 3x3 grid where players place the pieces. The pieces appear on the side and can be dragged to any cell in the grid.

Implementation Details

1

Drag-and-Drop Mechanics

The core functionality uses VB6's DragDrop method. Each puzzle piece is draggable and can be dropped into any grid cell.

2

Position Validation

When a piece is dropped, the program checks if it matches the correct position using a tagging system that identifies each piece's proper location.

3

Visual Feedback

Correct placements make the piece appear in the grid, while incorrect attempts return the piece to its original position.

VB6 Code Sample

The following code demonstrates the drag-and-drop validation logic. Each grid cell checks if the dropped piece matches its expected tag.

DragDrop Event Handler
Dim imgindex As Integer
Dim imgtag As String

Private Sub Image1_DragDrop(Index As Integer, Source As Control, X As Single, Y As Single)
    imgtag = Source.Tag
    imgindex = Index
    
    Select Case imgindex
        Case 0
            If imgtag = "11" Then
                Image1(0).Picture = Image1(9).Picture
                Source.Visible = False
            Else
                Source.Visible = True
            End If
        Case 1
            If imgtag = "12" Then
                Image1(1).Picture = Image1(10).Picture
                Source.Visible = False
            Else
                Source.Visible = True
            End If
        Case 2
            If imgtag = 13 Then
                Image1(2).Picture = Image1(11).Picture
                Source.Visible = False
            Else
                Source.Visible = True
            End If
        Case 3
            If imgtag = 21 Then
                Image1(3).Picture = Image1(12).Picture
                Source.Visible = False
            Else
                Source.Visible = True
            End If
        Case 4
            If imgtag = 22 Then
                Image1(4).Picture = Image1(13).Picture
                Source.Visible = False
            Else
                Source.Visible = True
            End If
        Case 5
            If imgtag = 23 Then
                Image1(5).Picture = Image1(14).Picture
                Source.Visible = False
            Else
                Source.Visible = True
            End If
        Case 6
            If imgtag = 31 Then
                Image1(6).Picture = Image1(15).Picture
                Source.Visible = False
            Else
                Source.Visible = True
            End If
        Case 7
            If imgtag = 32 Then
                Image1(7).Picture = Image1(16).Picture
                Source.Visible = False
            Else
                Source.Visible = True
            End If
        Case 8
            If imgtag = 33 Then
                Image1(8).Picture = Image1(17).Picture
                Source.Visible = False
            Else
                Source.Visible = True
            End If
    End Select
End Sub

Note: This code uses an array of Image controls (Image1) where indices 0-8 represent the grid cells and indices 9-17 represent the puzzle pieces.
