Yu-Gi-Oh! Dungeon Dice Monsters

What does randomization do to this game?

You will play the game in Free Duel mode or Tournament mode, depending on your chosen Progression method in the YAML. In Tournament mode you will start with the first division of tournaments available, beating a tournament for the first time will unlock checks. Eventually Division 2 (Reverse) will be found and you will gain access to those tournaments, as well as Division 3 (Dark). Once you have beaten every tournament in Division 3 except The Last Judgment, it will unlock.

In Free Duel mode you will start with the defined number of duelists unlocked (set in your YAML), defeating each duelist for the first time will unlock checks. Over time you will unlock more duelists as those checks are found by by players in the multiworld. Once you've beaten enough duelists, Yami Yugi will be unlocked.

What does another world's item look like in Yu-Gi-Oh! Forbidden Memories

Your item acquisitions take the form of having defeated duelists or tournaments, or collecting dice. As such, you'll have to check the BizHawk Client to know the actual items that were unlocked from those locations.

When the player receives an item, what happens?

Currently, the items are silently added to the player's inventory, which can be seen in the dice pool, Free Duel menu, Tournament menu, or Grandpa's Shop.

Can I play Tournaments in Free Duel mode and Free Duels in Tournament mode?

Playing in Tournaments when your progression mode is Free Duel will break logic. In Tournament mode you are free to play against as many duelists in Free Duel as you like.
