Recently my two daughters are keen on playing some Chinese stick puzzles. Playing these puzzles in GeoGebra is certainly better than in the paper-and-pencil environment. Since I have to add a red point to each stick in order to turn it, the sticks become matches and these puzzles are then called "Match Puzzles".
The 8 puzzles in this series are related to triangles and diamonds (rhombi). Another set of puzzles related to squares and rectangles is also available at http://www.geogebratube.org/material/show/id/991. Enjoy!
