The Free Gem Glitch is a glitch allowing players to obtain free gems. It works on all platforms.   
# Disconnect your device from the internet.   
# Enter your game and exit.   
# Turn off all automatic time and date settings   
# Change the date by 1 day   
# Enter the game, and you will receive a reward for logging in two days in a row.   
# Complete this until you reach the 900 coin, 2 gems reward.   
# Continue advancing by one day until you have as many gems as you want.   
  
If you only want gems, and do not want or need coins, there is a different method.   
# Complete steps 1 - 3 above   
# Instead of advancing time by one day, change it by one month.   
# Start the game, and you will recieve 5 gems.   
# Repeat until you have as many gems as you want.
