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

Example

The animation below shows the process of solving a level with the objective result 4. Available ingredients are the numbers 1, 2, 3, as well as the operators times and minus:

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>
