You can't join a tournament? Here are several possible reasons:
• Your balance is insufficient > Make a deposit before trying again.
• You have activated self-exclusion > You will need to wait until the period ends before you can play again.
• You have already participated in this tournament > Some tournaments are only accessible once or twice. To find out, check if Rebuys are available in the General tab.
• The tournament has not yet started > Come back at its start time to be able to participate.
And if this tournament is full or finished, take a look at the other tournaments available on CrazyDice. Daily, weekly, monthly tournaments… You have options.
