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 a 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.
