Add RecipientIcoSoKu
Set up the IcoSoKu puzzle by placing the number buttons randomly on the game ball. Now position the 20 dotted tiles so that all the dots surrounding each number button add up exactly to the number shown. You've triumphed if all the dotted tiles correspond correctly to all the numbers, with no tiles left over. To create new IcoSoKu challenges, simply switch a few of the number buttons and start over. This fun brainteaser helps develop logic, planning and math skills while exercising your brain. IcoSoKu can be solved every time, no matter how the numbers are placed. Great for home, office or travel, this brainteaser is suitable for ages 7 and up.
