Step 3: Scoring

  • Unlike Scrabble, when adding to an existing equation only the newly added tiles score points.
  • double-letter, triple-letter, double-word, triple-word squares work as usual
  • All equations earn a bonus depending on the actual numeric value of the equation.  This rewards equations of high value like '25x25=625' compared to ones of low value like '1+1+1+1=4'.
    • The calculation of the bonus is based on the equation value as follows:
      • Take the absolute value of the equation value (so that big negative equations are still rewarded!)
      • Take the square root of that number
      • Round up to the nearest integer
      • Yikes!  but it seems to work well.  you can use a calculator the first time.
    • The result is the bonus, which is added to the equation score before applying any double and triple word scores.
    • example:  '2+2=4'.  equation value = 4.  absolute value of that = 4.  square root of that = 2.  round up to get bonus points = 2.
    • example:  '3+3=6'.  equation value = 6, absolute value of that = 6, square root of that = 2.45, round up to get bonus points = 3.
    • example:  '3-20=-17.  equation value = -17, absolute value of that = 17, square root of that = 4.12, round up to get bonus points = 5.
  • When a player goes out, add to their score the sum of the unplayed number tiles.
<p>Great idea for a game. There is a similar ' number scrabble ' game. It is called ' Smath ' ! </p><p>http://www.kingarthurstoys.com/pressman+5200-06+smath+game</p>
<p>Math scrabble? Cool..</p>
<p>Definitely would be great to add parenthesis and variables. Don&rsquo;t know how that would work, but it be great to take the game from arithmetic to more advanced mathematics.</p>
How about adding parentheses for longer expressions? <br>
Wow: the perfect game for me! And for the ultra-nerdy; use binary or hexadecimal?
My head was spinning checking out your game calculations...i need this game for my 9yr old who doesn't want to use her head for maths and so this might help ...i'm praying...thanks
I remember wishing that there was a scrabble for math geeks, but now I can stop wishing and start making!
Cool!<br /> Is there any where to buy blank tiles?
Sometimes antique malls have big bowls of Scrabble tiles available on the cheap.
Thanks for this.&nbsp; I just finished making this game as a gift for my Mom's birthday.&nbsp; Her and my brother are word/number game freaks.&nbsp; They are going to love it.<br /> <br /> I bought a new game and marked the back of the tiles.&nbsp; I used a regular sharpy for the main numbers and operators.&nbsp; Then I used a fine tip sharpy to mark the value numbers in the lower right.<br /> <br /> I finished it off with a couple layers of clear coat just so the numbers don't wear out.<br /> <br /> Many Thanks,<br /> Kaspr<br />
I LOVE&nbsp;THIS!&nbsp;I'm a really bad speller, so I have always hated playing scrabble, but I&nbsp;love math. This is great. Thank you!<br />
What next - Boolean with TRUE / FALSE tiles..? <br /> <br /> L<br /> <br />
