About Holobrook

Holobrook is a free, fan-made Pokémon booster pack opening simulator and digital binder. Open packs, chase the cards you love, and build a collection, all in your browser, with no account and no real money.

What it is

It's a game about the fun part of collecting: the rip. Pick a set, tear open a pack, and see what you pull, with real card artwork, real rarities, and real-world value estimates. Everything you pull goes into your binder and your Collector's Journey. It's built for people who love Pokémon cards, whether you collect the real thing or just enjoy the thrill of the pull.

Where the card data comes from

Card names, artwork, rarities, and gameplay details come from the community-run Pokémon TCG API (pokemontcg.io), refreshed regularly so new sets appear soon after release. Value estimates are drawn from market data and are for entertainment only, they are not offers to buy or sell.
