The Domino High school festival is an annual event at Domino High School. Different classes set-up stalls to raise money.
On the thirtieth year, Anzu Mazaki's class won the most popular spot in a raffle and began setting-up their Carnival Games booth there. However, Goro Inogashira and his class took over their spot for their cooked Hiroshima-style okonomiyaki stall. Dark Yugi later faced Goro in a game of Griddle Ice Hockey to win back the spot.
