Crystal Challenge

50 gem puzzles to master. Tap a crystal to change it and its neighbours, match the target pattern and race the clock for 3 stars!

Tap. Transform. Match the pattern. Crystal Challenge is a bright, fast-thinking gem puzzle. Every level gives you a board of sparkling crystals and a target pattern. Your job is to turn your board into the target before the clock runs out. How it works Tap a gem and it changes to the next colour, along with the four gems around it. Red becomes purple, purple becomes green, then silver, then blue, and then the gem disappears. Every tap ripples across the board, so plan your moves and find the perfect sequence.
