You may need to upload a Gmail Sheets app if you wish to use the spreadsheet on your iPad or iPhone.

It works best on desktop units.

  • Click the button below

  • Select a square (cell) in the spreadsheet

  • Click on the 'fill color' icon in the toolbar

  • Select 'blue' to drop a marble in the jar!

The cell will turn blue and will be saved when you leave.

If you have any questions or you would like us to 'drop a marble in the jar' for you, please  feel free to contact me at
