Gameplay Decisions

Tournament Rules section 509 — 18 rules. From Riot's Tournament Rules for sanctioned events, last updated October 9, 2026.

509.1.: In competitions, players are responsible for considering options before taking actions.
509.2.: Once an action is communicated to an opponent, that action can’t generally be taken back.
509.3.: At low OPL, a player can reverse their most recent action and make a different decision for that action (including not taking it at all) as long as no new action has been taken by either player. The change in decision does not need to be immediate.
509.4.: At high OPL, a player can reverse their most recent action and make a different decision for that action (including not taking it at all) if no new action has been taken by either player and the following is true:
509.4.a.: The player wants to make a different decision for a spell or ability immediately after all choices have been made and communicated for putting it onto the chain. Example:
509.4.a.1.: A player plays Discipline indicating a unit. They immediately change their mind and choose a different unit, or choose not to play the Discipline at all.
509.4.b.: The player wants to make a different decision for playing a unit or gear immediately after playing it to a location. Example:
509.4.b.1.: A player plays Traveling Merchant to Reaver’s Row. They immediately change their mind and choose to play it to their base instead, or choose not to play it at all.
509.4.c.: The player wants to make a different decision immediately after making a choice such as moving a unit to a location or discarding a card. Example:
509.4.c.1.: A player moves Pouty Poro to Void Gate. They immediately change their mind and choose to move an additional unit there as well, or they decide not to move at all.
509.5.: Players can always ready runes they just exhausted for Energy or unrecycle runes they just recycled for Power as long as no new action has been taken and focus has not been passed.
509.5.a.: When changing decisions as described in 509.3. - 509.4., players can ready/unrecycle runes used for those decisions.
509.5.a.1.: Example: A player exhausts two runes and plays Pouty Poro from hand to their base, then immediately decides they do not want to play it. They may return it to their hand and ready those two runes.
509.6.: At high OPL, flexibility on gameplay decisions is not intended as a tool to allow players to reverse decisions after an opponent is required to indicate information that reveals that decision to be a tactical error.
509.6.a.: Example: Player A moves their 3 Might unit to a battlefield and passes focus. Player B indicates their 2 Might unit at that battlefield is now at 4 Might due to their legend, Wuju Bladesman. Player A can no longer change their decision to move to that battlefield and pass focus.
509.6.b.: Decisions made based on inaccurately represented public information may still be rewound at the discretion of the head judge. Inaccurately representing information to try to get a rewind is cheating.
509.7.: Intentionally attempting to reverse decisions to gain information from an opponent is considered angle shooting. Players may not change their decisions based on an opponent’s physical reaction or as a response to an opponent starting to take a game action. See 704.4. for more information on angle shooting.
509.8.: While changing decisions as described above is allowed, players must still maintain an appropriate pace of play. See 703.2 for more information on Slow Play.
