There is nothing called olympus cards on howrse.
You must buy the Olympus cards and hope you get one in there.
Simply enter the code that you find on your card. ;)
Xanthos came on the Olympus Cards. The cards are now sold out, and so the only way to get a Xanthos is to buy one off another player.
You have to buy an Owlympus card pack. then type in the code at my cards
You are going to have to buy a pack of cards for howrse and hope that you get it.
A booster card is a howrse card from the Olympus collection. No, it is nothing special. Buying the cards is like rolling the dice. You could either end up with great cards, or simply saddles, bridles, and even bags of apples. Card packs can vary anywhere from $8.00 to $145.00.
Howrse does not have promotinal codes unless you buy a packet of cards.
You can either get it from other players by trading passes, items, horses, or a combination of the three, or you have to get it in one of the Howrse card packs.
You can no longer buy Howrse cards
There are no codes for the sleipnir on howrse. People had to buy cards with real money in order to get the codes and they would not give them out to random people.
To receive the codes you must have bought the Olympus Cards. You should not trade card codes because each code can only be activated once. Someone may make you pay thousands of equus for a code which has already been validated.
