Place the given digits into the grid so that no digit appears more than once in any "word" and that the sum of the digits in the word match the indicated sum. Sometimes there is one digit left over; don't let that rattle you.
How to Play.
Drag letters from the "palette" on the left into the grid to place them. You'll know you've solved it when all the sums turn green. Click on a cell to get a keyboard-sensitive cursor.
