If you are a steam player, then you must create an spiral knights account( not steam one) and then we start the steps of buying ce with "PHONE CREDIT"! (Dramatic)

1. When clicking the purchasing ce price icon in non-steam spiral knights account, there should be a button saying mobile phone( or maybe something else), after you put a cross next to it click the BIG button under it .

2. You will be redirected to the spiral knights website, there will be a list of options of how much you want to purchase( WARNING: you can only buy ce with phone, you can't buy any DLC with it.

3. After you clicked the one you want, type your phone number and then you will receive a message from the website on your phone, reply Y to it if you are sure that you want to buy it.

4. Wait for a seconds on your computer, your knight will receive the ce. The system will take some of your phone credit( depends on how much you bought)

5. Open your spiral knights( second one), and trade with yourself, pass the non-steam's ce to the steam one. Enjoy

(If you have a normal spiral knights user, skip part 5.)

You can buy your phone credit from most of the shops such as: One stop, Tesco, Co-operate etc, so basically, you used your coin and notes to buy ce without using creditcard!(WARNING( not again): Using creditcard purchase is more profitable than phone credit purchase though)

Most people probably know this but I want to mention it anyway :P
