Some 19 operators have now been approved to offer sports betting in Germany, including Bet-at-Home, which secured an online licence earlier this month.

The Third State Treaty states that customers are limited to a monthly betting limit of €1,000 (£891.96/$1,190.79), though a small number of customers can increase these limits to €10,000 or €30,000.
Deposits are limited until players pass verification checks, while licensees have to integrate with the national self-exclusion system OASIS and betting markets must be approved by the Regional Council.
