What puzzle level do you have to reach before you can play in the weekly tourneys?

Don't know the exact number, but I'm on game 1,488 and I've been playing tourneys for awhile. That's why I'm thinking its likely 1,000 or 1,200 that triggers it. It could also have to do with the number of coins earned or Brilliance points. This is only one of a myriad of things they don't explain. That's why I'm just having fun playing it, not to compare with others. (Must admit coming in third in the last tourney surprised me, and I got a kick out of it becauseI didn't play more than my usual games during the tourney. Have fun!

The level that triggers tournament is 100
