Description (original)

Blocku is a math based jigsaw puzzle. Blocku will come with a few pre-made puzzles. It will have a teacher edit tool where teachers can make their own puzzles. Puzzles can be as complicated as a castle or as simple as a square. The teacher will be given a grid where he/she can specify how the puzzle is supposed to look. Then the teacher chooses what type of operator he/she wants (+, -, x, /). Then the teacher inputs the answer. The activity randomly chooses what number will appear on the sides of each square.

To complete each puzzle the student has to match the sides of squares together so that the numbers finish the math equation at the top of the screen. The puzzle is completed when all pieces are used and are in the correct positions. Below is an example of how a game may progress.


  • Can choose to use pre-made puzzles
  • Can choose difficulty
  • Can choose grid size
  • Can choose the set of numbers
  • Can choose operators used
  • Is given the answer then the puzzle


  • Can set difficulty
  • Can set grid size
  • Can set the set of numbers
  • Can set the operators used

Game Suggestions

I think it's great.  Three points:
1)  Users probably don't want to play many games of the same operation
    (e.g. x+y=10), and the teacher probably doesn't want to create a new game
    for every operation.  You should allow users to select a range of
    operations (e.g. numbers up to 12, + - and *) and have the game select a
    random operation from the set for each game.
2)  There are some interesting possibilities for using network collab
    between users and teachers, but work on that last.  To start, users should
    just punch in the operation (or range of operations) when the activity
    launches.  Teachers can just tell the students what settings to use, and
    then look at the screens to verify.
3)  The visual structure of the game seems almost identical to Gnome's
    Tetravex.  In the spirit of Open Source, you should consider reusing the
    Tetravex gameboard display code.

  Looks great Mark!  Feel free to get in touch with me if you need any
help with implementation.
  I agree with Greg that this would be a good target for PyGame.
Regarding the game design, you should consider adding some sense of
progress, or else players will get tired quickly. Some ideas:
 - Start with two cards, gradually ramp up to 9.
 - There needs to be a good "snapping" mechanism when dropping, so
   users don't get frustrated by trying to line the cards up.
 - Adding the ability to rotate the cards in 90 degree increments would
   add to the challenge.
 - Your notion of customization seems limited to replacing the square
   with a graphic, which might obscure the number.  Is this really a good
   way to customize it?
 - I agree with Ben that when you start the game you should first
   select which types of puzzles (* + - / etc) you want, how many
   squares, whether rotation is allowed.  No need for the teacher to be
 - Why limit it to numbers?  E.g. how about comparisons like "X is
   heaver than Y" and on the sides of the cards are things like
   "elephant", "bacteria", etc.  Or "X is newer than Y", etc.  This is
   where customization would be cool.  Let the teacher define a
   relationship, and input a series of terms, and define which pairs meet
   that relationship.  This would be called a "set", and could be
   exported to the Journal.
   Good luck with your project!

Very clever.  I just cut made a cut out of the game out of paper.  My
1st grade niece played with it for over half an hour.  It will be a
hit on her XO.

  Mark, this looks like a brilliant little activity.  Simple, fun gameplay, extensible.  Really great.
Some thoughts:
1. I'd love to see this as primarily a PyGame activity, with just enough "Sugar" to run it on Sugar 
   easily, but also easily available as a Windows or Mac activity.  If done well, this is precisely 
   the sort of activity that could cross over.  (Which is, in fact, how I'd like to see most Sugar 
   games built.)
2. Always think a little bit (but not too much) about assessment.  The student knows they're 
   getting better because they are "leveling up".  The teacher knows the kid is getting better 
   because... how?  Game data is pushed up to a server... somehow?  Dunno if anyone is paying 
   attention to this   question, but it would be great if there were a simple way to allow   
   teachers to 
   aggregate "high score" data, which really doubles as assessment data in cases like this.
   A great start.  I look forward to seeing what it becomes.
