YugiDoku

About YugiDoku

YugiDoku takes the immaculate grid format to Yu-Gi-Oh cards. It is an unofficial fan game made by Card Prices, a Yu-Gi-Oh card price site, and is not affiliated with Konami. Its daily grids are numbered; grid number 12 fell on 5 October 2026.

Each day's board has three clues across the top and three down the side. Clues can be an attribute such as WIND or DARK, a monster type, a card kind like Link-3 or Xyz, an ATK or DEF range, a word in the card's text, a debut year, a rarity or a market value. You tap a slot, search for any card and play it, and it sticks if it matches both its row and its column. You have nine cards in total, right or wrong, and wrong ones go to the Graveyard. Your score is Rarity: the share of players who picked the same card for each slot, added up, with empty slots counting 100, so lower is better and an unusual correct pick is worth more.

Two more daily games sit beside the grid. Cardle hides one well-known monster a day and gives you eight guesses; each guess shows how close you are on attribute, type, Level or Rank, ATK, DEF and debut year, and a pixelated scan of the art sharpens as you go. Higher or Lower shows a printing and its market price, and you call whether the next one sells for more or less, ten calls in the daily run. There is also Grid Duel, a tic-tac-toe on the same kind of clue grid against the computer, a friend or a rated opponent, and an unlimited grid mode.

It suits players and collectors who know the card pool well, from old Duel Monsters cards to recent Link and Pendulum monsters. You can play as a guest; signing in with a Card Prices or Discord account keeps your streak, XP and rank and puts you on the leaderboards. Past grids and Cardle answers are kept in an archive.

How to play YugiDoku

1. Open yugidoku.io and choose the daily Grid.
2. Read the three clues across the top and the three down the left side.
3. Tap a slot, search for a Yu-Gi-Oh card and play it; it stays only if it fits both its row clue and its column clue.
4. Fill as many of the nine slots as you can with your nine cards, never using the same card twice.
5. Check your Rarity score when the board ends, then open Answers to see every valid card for each slot.
6. Play Cardle and the Higher or Lower daily run if you want more, and come back after midnight UTC for the next grid.

Tips

• Save your surest cards for the hardest slots; every card you play uses one of your nine, right or wrong.
• Generic support cards and staples are picked by many players, so a less common card that fits scores a lower Rarity.
• Text clues such as Destroy or Once per turn match a huge number of effect monsters; pair them with the stricter clue first.
• In Cardle, a yellow ATK or DEF tile means you are within 300 points, so adjust in small steps.
