Touchop

Touchop is an mathematical puzzle game. Each level of the game provides a fixed set of formula fragments or mathematical operators. These fragments have to be combined to formulas such that the given objectives are met.

Technical features:

  • UI concept is based on drag-and-drop and compatible with the upcoming tablet design
  • Non-unique solutions appeal to creativity and make mathematical concepts explorable
  • Platform independent and light weight code based on SVG, XSL, and JavaScript

120 Levels are currently implemented for the following mathematical domains:

  • Arithmetics
    • Plus/Minus
    • Multiplication
    • Division
    • Power
  • Self defined variables
  • Expressions with free variables
  • Function plots
    • Linear Functions
    • Polynomials
    • Hyperboles
  • Parametric plots
    • Trigonometric functions
  • Turtle graphics
  • Coming soon: Image processing

The level definition for this example looks like this:

<touchop>
 <test domain="algebra" win="4"/>
 <op name="minus" xy="100,200"/>
 <op name="times" xy="200,300"/>
 <atom value="1" xy="100,100"/>
 <atom value="2" xy="200,100"/>
 <atom value="3" xy="300,100"/>
</touchop>
