This is an awesome number game which will challenge your capability both of memory and logic.

There are 4×5 grids filled with 0~9 and 0~-9, totally 20 numbers.

Each time you can select two grids which will pop up two numbers. You take the tens digit and return the units digit to the two grids averagely, if the product is equal or greater than 10. Otherwise, the two grids will remain unchanged.

If one or two of the number is zero, there will be a reassignment of the two grids, and the sum still be the same.

Time is limited, but you can get another round by complete this one, which means more than 17 grids are filled with small number, like 1,2 or 3. And to win more time, this round must be ended with positive number.

May you be smarter with Decimalism.
