Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.splinterlands.com/cards/booster-packs/purchasing-booster-packs.md). # Purchasing Booster Packs Players can purchase Booster Packs (while supplies last) from the current main set, using [Credits](https://docs.splinterlands.com/dec/splinterlands-credits) or [Dark Energy Crystals](https://docs.splinterlands.com/dec/dark-energy-crystals-dec). Each card in a pack has a certain percentage chance of being a Common, Rare, Epic, or Legendary rarity, as well as a small chance of being a Gold Foil version of the card. Chances of flipping Gold Foil and Legendary cards can be doubled by purchasing *Alchemy* and *Legendary* Potions at a rate of 1 charge per card in a pack. Every Booster Pack is guaranteed to contain at least one card that is Rare or better. Booster packs can be purchased on the [**Splinterlands Shop Page**](https://splinterlands.com/shop/packs), the [non-card market](https://splinterlands.com/market/other-items), as well as various third-party platforms such as [Tribaldex.](https://tribaldex.com/)
