|The 2016 International Challenge June is one of the last chances to test players best battle strategies in the 2016 season! Top players were eligible to earn Championship Points as progress toward an invitation to the Pokémon World Championships in San Francisco, California, in August 2016. All battles were Double Battles played in Pokémon Omega Ruby and Pokémon Alpha Sapphire.
The competition used the Double Battles format and players had to register 4 to 6 of their level 1–100 Pokémon to their Battle Box. Pokémon automatically became Level 50 during battles. A 15-minute time limit for each match was automatically enforced in-game, beginning at the start of each battle. If the outcome had not been determined when the time limit expired, the game automatically applied tiebreakers to determine a winner. At the beginning of each battle, players had 90 seconds to select their Pokémon to battle with. At the beginning of each turn, players had 45 seconds to select a move or change Pokémon in battle. If a player had not made his or her selections at the end of this period, the game automatically made selections for the player. Players could battle up to 15 games per day of the competition. Any unplayed games would carry over to the following day.
