Actually, a shuffle game is a good idea to make because it will increase your skill. I never actually made one, but here's some stuff that might be helpful.
To Split An Image Into Four Parts:
Load Bitmap "Whatever.bmp",1
Get Image 1,0,0,Screen Width()/2,Screen Height()/2
Get Image 2,Screen Width()/2,0,Screen Width(),Screen Height()
Get Image 3,0,Screen Height()/2,Screen Width()/2,Screen Height()
Get Image 4,Screen Width()\2,Screen Height()/2,Screen Width(),Screen Height()
ClickBox Function:
Function ClickBox(x1,y1,x2,y2,Click)
Clicked=0
If MouseClick()=Click
If MouseX()=>x1 and MouseY()=>y1 and MouseX()=<x2 and MouseY()=<y2 Then Clicked=1
EndIf
EndFunction Clicked
For the code to split an image into four parts make sure that you change the bitmap name into whatever the actually bitmap file name is that you want to load before you run the code.
For the box function should be put at the end of your code and not in the main loop. Its a very simple function it just returns a value of 1 or 0. You just got to put the coordniates in first and then what mouse button you want.
So, like this:
Box 0,0,100,100
rem Main Loop
Do
If ClickBox(0,0,100,100,1)=1 Then Print "You Clicked The Box"
Sync
Loop
Function ClickBox(x1,y1,x2,y2,Click)
Clicked=0
If MouseClick()=Click
If MouseX()=>x1 and MouseY()=>y1 and MouseX()=<x2 and MouseY()=<y2 Then Clicked=1
EndIf
EndFunction Clicked
That should get you started with your shuffle game, let me know if you need any help
