A Sneak Peek event, also known as a Sneak Preview, is an event held at Konami's Official Tournament Stores to celebrate a new TCG booster pack, occurring the weekend before the new packs are sold. A new TCG booster pack is released every three months.
For an entry fee, players receive five of the new booster packs and a special Sneak Peek promo card (while supplies last). Using these cards, players build and Deck and compete with other Sneak Peek participants. Players get to keep all the cards from the packs they open. All Sneak Peek participants have a chance to win an exclusive Sneak Peek Game Mat as a door prize or raffle.
