The basic mechanics of Ruby and Sapphire are largely the same as their predecessors'. As with all Pokémon games for handheld consoles, gameplay is in third-person, overhead perspective and consists of three basic screens: a field map, in which the player navigates the main character; a battle screen; and the menu, in which the player configures their party, items, or gameplay settings. Players begin the game with one Pokémon, and can capture more using Poké Balls. They can also use their Pokémon to battle other Pokémon. When the player encounters a wild Pokémon or is challenged by a trainer to a battle, the screen switches to a turn-based battle screen where the Pokémon fight.[1] During battle, the player may use a move, use an item, switch their active Pokémon, or flee, although fleeing is not an option in battles against trainers. All Pokémon have hit points (HP); when a Pokémon's HP is reduced to zero, it faints and cannot battle until it is revived. If the player's Pokémon defeats the opposing Pokémon (causes it to faint), it receives experience points. After accumulating enough experience points, it will level up; most Pokémon evolve into a new species of Pokémon when they reach a certain level.[2]
Apart from battling, capturing Pokémon is the most essential element of Pokémon gameplay. During battle with a wild Pokémon, the player may use a Poké Ball on them. If successful, the Pokémon will be added to the player's active party, or stored if the player already has the maximum six Pokémon in their party.[3] Factors in the success rate of capture include the HP, status effects such as Paralysis or Sleep, and the strength of the Poké Ball used: the lower the target's HP and the stronger the Poké Ball, the higher the success rate of capture is.[4] Other trainers' Pokémon cannot be captured.
New features[edit]

The most prominent change in the battle mechanics is the introduction of double battles, in which the opposing parties each use two Pokémon at the same time. Consequently, certain Pokémon moves can affect multiple combatants at once.[5] Multi battles were added alongside double battles. They are identical to double battles, but there are two trainers to a side, each controlling one of the two Pokémon sent out. Also new to the games are innate abilities and natures; the former is shared by every Pokémon of a certain species, while the latter may vary among a particular species. Abilities grant their holders certain powers in battle, such as immunity against certain types of moves or strengthening a certain type of move. Natures, like innate abilities, affect the strength of Pokémon in battle; however, they affect the stats of the Pokémon rather than directly affecting the strength of the moves.[6] Another stat introduced in Pokémon Ruby and Sapphire is Condition, an important factor in Pokémon Contests, mini-games in which participants perform moves before a judge. Both Pokémon and their moves have a Condition, which is increased by using Pokéblocks, which are candies made from berries.[7] Secret bases were added as a one-off feature where players could open up a hole in the world and customize the area with various items picked up in-game. Players who linked up with others who set up secret bases were able to battle an NPC version of that trainer within their secret base.
Like Pokémon Gold, Silver, and Crystal, Pokémon Ruby and Sapphire keep track of real-life time; this influences events like tides and berry plant growth. However, unlike their predecessors, Ruby and Sapphire do not differentiate between day and night. Also, due to the differences in the technical specifications of Game Boy link cables and Game Boy Advance link cables, Ruby and Sapphire cannot be linked with Pokémon games of previous generations; one cannot battle with or trade to the previous generations.[8]
Connectivity to other devices[edit]
The Eon Ticket could be scanned in by the e-Reader to go and catch either Latios or Latias, depending on the game.
Ruby and Sapphire have limited e-Reader support. Nintendo released Battle-e Cards, a set of e-Reader cards that contained trainer battles in which the player could see previously-hidden Pokémon.[9] A special e-Reader card called the Eon Ticket was also released; obtained through the Mystery Gift function, the Ticket allows the player to reach a place called Southern Island. There, the player faces either Latios or Latias, depending on which version of the game is used.[10]
Ruby and Sapphire are also able to connect to the GameCube games Pokémon Colosseum, Pokémon XD: Gale of Darkness and Pokémon Box: Ruby and Sapphire. In the former two, once players reach a certain point in the game, they are able to transfer Pokémon between Colosseum / XD and Ruby / Sapphire.[11] Additionally, those who pre-ordered Colosseum were able to access the Pokémon Jirachi and see a preview of the movie Pokémon: Jirachi Wish Maker. Pokémon Box allows players to store and organize their Pokémon on the GameCube.[12] Also, in the European version of Pokémon Channel, players could receive a Jirachi at a certain point in the game, which they could then transfer over to Ruby or Sapphire.
