Top Tips for Using Casino Promo Codes

Now you know all the basics of the types and use of gambling bonus codes. Take your online casino experience to the highest level by reading our practical suggestions on how to make the most of these virtual keys to bonuses galore.

  1. Check code validity period ⏰: The validity period is an essential part of every bonus code. The validity periods differ wildly between various casinos. However, most of the welcome bonuses have year-long or indefinite validity. The same doesn’t apply to bonus codes used for campaigns with a short lifetime. Some promotional codes may be valid for only a week or two. Especially the ones representing a seasonal campaign like Christmas or Easter.
  2. Understand the T&Cs 📜: Every bonus code is connected to a particular bonus and that promotional offer is tied to terms and conditions. Make sure to understand the rules of an offer before redeeming the code. As the majority of casinos allow a single activated bonus, you don’t want to have an active bonus that doesn’t really serve your needs as a gambler.
  3. Maximise your opportunities 📈: Many casinos have bonus codes. As a player, it makes sense to redeem as many as you can. There’s no rule that says you can’t have multiple activated bonuses in separate online casinos. Find the best casino bonus codes listed on our site by using the casino comparison tool.
  4. Avoid promo code abuse💔: Abusing bonus codes is a big no-no! Online casinos will remove your entire bonus and any winnings in a heartbeat, should they discover that you have tried to game the system. Bonus code abuse involves using the same bonus more than a single time. For example, using other peoples’ identities or virtual private networks is going to get you banned from the casino.
