My Scrabble enthusiast mother, on her 70th birthday, said SEVENTY was worth 13. Being a Bingo, it's actually 63. If you triple the V or Y you get closer: 71. (This isn't actually possible because the way a Scrabble board is set up, in order to hit one TWS you have to hit the other.) You can't score 70 with SEVENTY.
Which number words can be worth their value when laid down on an actual Scrabble board?
For this exercise, don't worry about how you might score the word in an actual Scrabble game. Also, don't use blank tiles.
Refer to the tile distribution and scores
And also, remember to make sure your word will fit on an actual Scrabble Board
