Orb (Puzzle & Dragons: Super Mario Bros. Edition)

Orbs are puzzle pieces in the Puzzle & Dragons series that the player must match three or more in tile matching puzzles. They appear in five different colors (red, blue, green, yellow, and purple) in a 6-by-5 board called the Orb field. When the player moves Orbs around so that three or more line up horizontally or vertically, the Orbs disappear and new ones fill the Orb field from the top.

There are five main types of Orbs that can appear on the Orb field: red, #0099ff, darkgreen, gold, and purple. As their names imply, each Orb type represents the elemental attributes of enemies (Fire, Water, Wood, Light, and Dark). pink represent life recovery.

History
In Puzzle & Dragons: Super Mario Bros. Edition, Orbs suddenly appear at Princess Peach's Castle. After inviting Mario to her castle to see them, Princess Peach is kidnapped by Bowser and the Orbs are stolen by his minions. Kamek casts a spell with the power of the Orbs to flood the Mushroom Kingdom with them. After receiving a letter from Bowser about Peach's capture, Mario and a Red Toad decide to use the power of the Orbs as well to defeat the Koopa King and rescue the princess.

Gameplay
To clear Orbs from the Orb field, the player must match three or more horizontally or vertically. The player drags an Orb with to adjacent positions, swapping with the Orb already there. As long as the player does not let go of the Orb, they can move it as much as necessary within five seconds once they start moving it, allowing them to arrange for Combos in a single turn. After completing this, all matched Orbs are removed from the Orb field and accounted for as damage to enemies. The Orb field then cascades all Orbs down and fills the Orb field once more; this may result in more Combos, known as "skyfall combos".

Damage is based on what colors were matched in the Combos: for example, a basic combo of three red (Fire) Orbs will have any teammates that is Fire-attribute deal its damage equal to its base attack (ATK) to one enemy. When Heart Orbs are matched in a Combo, it restores health to the team based on the team's total health recovery stat (RCV). Combos of more than three Orbs will increase the damage dealt for each additional Orb. Making multiple Combos on the same turn will boost all damage or healing for all teammates regardless of colors matched, while separate combos of the same color further multiply the damage dealt. Single combos of five or more Orbs will activate an attack that hits all enemies on the field. Damage will be affected by both the enemies' defense power and its attribute, for Fire damage against a Fire enemy will work, but will be boosted against a Wood enemy and decreased against a Water enemy, and so forth in a rock-paper-scissors relationship; Light and Dark enemies are solely weak to the other type.

Some teammates have Skills that change Orbs on the Orb field to different types, whether it be a single Orb type (changing Heart Orbs to Dark Orbs), or two (changing Light Orbs into Wood Orbs and Heart Orbs into Fire Orbs). Some Orb changing Skills can change the entire Orb field into several Orb types or even a single one (i.e. Iggy's Hurricane and Ludwig's Volcano).

Branching paths
During courses, player may occasionally encounter a branching path in a course, with two different colored Orbs hovering above each path, representing which Orb color the player needs to clear most of from the Orb field to take its path: for example, if the player wishes to take the path with a Fire Orb above it, they will need to clear more Fire Orbs than other Orb types to proceed. The player will remain at the branching path until they clear either Orb colors at that branching path, and the player's Skill counter will not decrease until they do so (the player can use Skills that change Orb types, however). What appears at the path can vary from signs, Warp Pipes, to Gold Blocks. Proceeding on a path with a sign allows the player to continue on the "main" path, while entering Warp Pipes takes them to different areas before returning to the main path. Gold Blocks in branching paths do not show which Orb type the player needs to clear most of, but clearing with the right Orb type will cause the Gold Block to produce a Beanstalk, taking the player to another area. If the player clears the same amount of Orb types for a Gold Block as a Warp Pipe or a sign, the player automatically takes the path of the latter instead.

Orb configurations
Each course has a certain configuration of Orbs on the Orb field. All six types of Orbs can appear at once, though some courses may disable elemental Orbs or even Heart Orbs. In several courses, some branching paths require an Orb color that is not present on the Orb field, and thus requires the player to bring an ally that can change Orbs into that color.
