Quick Answer

Affiliate codes primarily benefit the player entering them (e.g., enhanced rakeback and better RTP). Referral codes primarily reward the person who referred you — typically a commission or bonus when you sign up and play. On Duel.com, DUEL5 and FUSE are affiliate codes that benefit the player.

Definitions

Affiliate Code

An affiliate code links a player's account to an affiliate's programme tier. The player receives enhanced benefits (higher rakeback, better RTP, exclusive bonuses). The affiliate earns commission on the referred player's activity.

Example: Entering DUEL5 on Duel.com → You get 50% rakeback + 100% RTP on Originals.

Referral Code

A referral code is typically a personalised link or code shared by existing users. When a new player uses it to sign up, the referrer receives a reward (bonus cash, rakeback, free spins). The new player may also receive a sign-up bonus.

Example: A friend shares their personal referral link → They earn a commission when you deposit; you may get a welcome bonus.

Why Affiliate Codes Are Better for Players

For regular players, affiliate codes like DUEL5 typically provide more long-term value than referral codes because:

  • 1.Ongoing — rakeback never stops; referral bonuses are one-time
  • 2.No wagering requirements — rakeback is withdrawable immediately
  • 3.Scales with volume — more you play, more you earn
  • 4.Transparent — fixed percentage, predictable returns

Can I Use Both?

On most platforms including Duel.com, you can only have one affiliate/referral code per account. Affiliate codes and referral codes typically occupy the same field. Choose the option providing the most long-term value — affiliate codes like DUEL5 with 50% rakeback are generally superior.

Key Takeaways

  • Affiliate codes benefit you (the player) with ongoing enhanced rewards
  • Referral codes primarily reward the person who referred you
  • DUEL5 and FUSE are affiliate codes — you are the primary beneficiary
  • For regular play, affiliate code rakeback outperforms referral sign-up bonuses
