Tk666io's referral program rewards you for every successful referral with ৳500 Bonus is available. A referral is counted as "successful" when your friend registers and makes their first deposit of at least ৳500.
How to get your referral code:
- Log in and from the profile menu "Referral Program" Select
- You'll see your personal referral code — copy it
- Send the code to your friend and ask them to enter it in the "Referral Code" field when registering
- When a friend registers and deposits ৳500, ৳500 in bonus will be credited to your account
A few important things to note: The referral bonus carries a 3x wagering requirement — meaning if you receive a ৳500 bonus, you'll need to place ৳1,500 in bets before withdrawing.
