The welcome bonus at Arlekin is split across your first four deposits:
1st Deposit: 100% match up to 200 $/€ or 1 BTC + 100 FS
2nd Deposit: 50% match up to 300 $/€ or 0.5 BTC
3rd Deposit: 75% match up to 150 $/€ or 0.5 BTC + 50 FS
4th Deposit: 50% match up to 200 $/€ or 1 BTC
What makes this welcome bonus different than most others is that the deposit match has a dollar limit but also provides players with the chance to match up to 1 BTC (which has a significantly higher value than the dollar limit).
Each of these bonuses comes with a $30 minimum deposit.
