This is an update to a math adding puzzle game I posted a few years ago. The previous version was limited and used dozens of image files for numbers. I added a new board display method, it should look the same size on every desktop. This version has more grid sizes, and some sound effects, and a simple Help screen.
Basically you click to remove/add numbers in the grid so that the ones left on add up to the number shown on the edges. The rows and columns numbers must total up to the number on the edge. Make all the edge numbers highlighted to solve the puzzle and advance to a bigger grid size. You can change grid sizes by pressing +/- keys.
It's nothing great, and probably could be done in half the amount of code, I just wanted to work on something today and landed on this for some reason.

Code: (Select All)
'============
'RoCoLoco.bas v2.0
'============
'Row & Column number adding puzzle game.
'Based on popular math game found online.
'Coded by Dav for QB64-PE, Nov/2022
'New for v2: * Playing board now adapts to users desktop size.
' It should displays the same on every screen.
' (Screen size is not hardcoded to specific size)
' * No longer uses external .jpg images for numbers.
' * Change grid size using the +/- keys.
' * Added HELP screen (not much) - press H for it.
' * Added some cheap sound effects.
'
'~~~~~~~~~~~
'HOW TO PLAY:
'Click numbers inside the grid to turn them on/off.
'Each row/column of red number totals must add up to the number
'on the edge of the grid. When they do, the edge numbers will
'turn on too. You must tun on all the edge numbers to solve it.
'
'~~~~~~~~
'CONTROLS:
'
'You can change the grid size anytime by using +/- keys.
'H = Show a simple help screen
'SPACE = Generate a new puzzle grid
'ESC = Quits game
