Clinx

Clinx is a colour-matching game based on the legendary pedras do mardis gras or carnival stones of Machu Khlixhu. These rare and mysterious gems changed colour when hit with a gold object and this magical property soon became part of religious festivals. However, the stones could only change colour a certain number of times depending on their age and fragility. Once they had been struck that number of times they would remain that colour forever.
