Tournament fee
Fees for tournaments from which Status Points are paid to players are included in the buy-in amount.
The fee in regular tournaments is 9% of the buy-in amount, and you can see this in the tournament lobby by hovering your mouse over the 'i' icon next to the buy-in amount.
Twister games fee is 7% of the contribution amount. There is no information on fees in the Twister lobby, but you can check through the game history how much you paid to enter and how much of it is the tournament fee. (For example, €2 Buy-in = €0.14 Fee => 1.4 SP; €0.50 Buy-in = €0.03 => 0.3 SP; €1 Buy-in = €0.07 Fee => 0.7 SP).
Fees in SNGs are: 6% for Heads Up games, 9.1% for Turbo, 8% for Hyper-Turbo, 9% for Double or nothing, and you can see this in the tournament lobby if you hover your mouse over the 'i' icon next to the amount of the deposit.
