Pokémon prerelease events in the UK: a first-timer's guide
A Pokémon prerelease is a casual tournament at a local game store where you play with a new set before its official release date. You buy a Build & Battle Box at the event, open it, build a 40-card deck and play other people at the table.
Prereleases run at official Play! Pokémon Stores, and the official way to find one is the Play! Pokémon Event Locator. This guide covers how the events work in the UK, what is in the box, the rules and what to take with you. Every detail comes from Pokémon's own pages, as of October 2026.
When prereleases happen
Pokémon's event requirements for stores describe prereleases as quarterly events. Stores schedule them across a set two-week window, and players get the new cards up to two weeks before the release date.
The latest one was for Mega Evolution, Delta Reign. Pokémon's UK announcement gives a release date of 6 November 2026, with select Play! Pokémon Stores selling the Build & Battle Box from 24 October 2026. Our Delta Reign guide covers the set itself, and Pokémon sets in 2026 lists the rest of the year.
How to find a prerelease near you
Use the Play! Pokémon Event Locator. It is the official list, and every store on it is a registered Play! Pokémon Store.
- Open the locator and enter your town or postcode.
- Look through the results for Pokémon TCG events with "Prerelease" in the name, in the two-week window before the set's release date.
- Open the store's own website or social pages for the time, the entry price and whether you need to book.
Each store sets its own times, price and booking rules. Check them with the store directly, and book a place if the store takes bookings.
Our city guides list stores that appear on the locator. For example, where to buy Pokémon cards in Manchester and where to buy Pokémon cards in London both name Play! Pokémon stores that run events.
What is in a Build & Battle Box
The Build & Battle Box is the product at the centre of every prerelease. For Delta Reign, Pokémon lists the contents as:
- four Delta Reign booster packs
- a 40-card ready-to-play deck, with key cards from current and earlier expansions
- one of four foil promo cards
The four Delta Reign promos are Masquerain, Magmortar, Enamorus and Kommo-o. You get one at random, and the deck is built around it.
Pokémon's store requirements add that each booster pack holds 10 cards and 1 Basic Energy.
If you cannot get to an event, the Build & Battle Boxes go on general sale when the set releases.
What is in a Pokémon prerelease kit
"Prerelease kit" is the store-side name. Pokémon's store requirements say each Prerelease Kit contains 10 Build & Battle Boxes, plus booster packs for prize support. Stores get an allocation of kits for their events.
As a player, you do not buy a kit. You buy one Build & Battle Box at the event, and that box is your card pool for the day.
Pokémon prerelease rules
The prerelease format is smaller than the normal game. From Pokémon's prerelease announcement:
- Your deck has 40 cards, not 60.
- Each player sets aside four Prize cards at the start, not six.
- You build the deck from the cards in your Build & Battle Box, which includes the ready-made deck and the four booster packs.
The card pool is small, so you can rebuild your deck between games. Pull cards from your four new packs into the ready-made deck when they suit your promo card.
The rest of the event is up to the store. Ask how many rounds they run, how long each round lasts and how prizes work. Pokémon describes the format as quick games for new and experienced players.
What to bring to a Pokémon prerelease
The essentials:
- Your Play! Pokémon Player ID. Pokémon's Player ID guide explains how to make one through a Pokémon Trainer Central account. If you do not have one, you can also get one at an in-person event, so do not let it stop you going.
- Money for the entry. Check with the store whether it takes cards or cash only.
- Card sleeves for 40 cards or more. Sleeves protect any good pulls while you play.
- Damage counters and a coin. Some stores have spares. Bring your own if you have them.
- Basic Energy. Your box has some, but a few extra of each type make deck building easier. Ask the store if they supply it.
- A deck box or toploaders for anything valuable you open.
Arrive a little early. Opening the box and building the deck takes time, and the first round starts on the store's schedule.
Should a collector go to a prerelease?
Yes, if you enjoy opening packs. A prerelease is the earliest official way to open a new set, and the foil promo comes in the Build & Battle Box. You also meet the local store and its players, and that is where you hear about the next event.
A prerelease is not a way to buy sealed stock in quantity. You get one box for one entry, and the cards are for playing. If you want to buy the set at release, our guide on where to buy Pokémon cards in the UK covers the shops.
Common questions
How do I find a Pokémon prerelease in the UK?
Use the official Play! Pokémon Event Locator at events.pokemon.com. Search by town or postcode and look for Pokémon TCG prereleases in the two weeks before a set's release date. Then contact the store for the time, price and booking.
What is in a Pokémon prerelease kit?
A Prerelease Kit is what stores receive: 10 Build & Battle Boxes plus booster packs for prizes. Each player gets one Build & Battle Box, which holds four booster packs, a 40-card ready-to-play deck and one of four foil promo cards.
What are the rules at a Pokémon prerelease?
You play with a 40-card deck and four Prize cards, instead of the normal 60 cards and six Prize cards. You build the deck from your Build & Battle Box at the event. The store sets the number of rounds, the round length and the prizes.
What should I bring to a Pokémon prerelease?
Your Play! Pokémon Player ID, the entry money, card sleeves, damage counters and a coin. Extra Basic Energy and toploaders for good pulls also help. You can get a Player ID at an in-person event if you do not have one yet.
Do I need to be good at the game to go?
No. Pokémon describes the prerelease format as an introduction for new players as well as a first look at the set for experienced ones. The games are short, and the ready-made deck in the box lets you play from the first round.
Where this fits
Prereleases are the playing side of a new set. The collecting side is in which Pokémon sets hold their value and the Pokémon cards UK hub. Release dates for every new set are in Pokémon sets in 2026. Looking at 2027? See the Pokémon sets 2027 list.
