Labs are a more experimental take on game modes in Legends of Runeterra, having a focus on variety and experimentation. The rules of Labs change periodically, usually with patches, and each named set of rules themselves is called a Lab. Each Lab is usually available for limited amounts of time. It is accessed from the Play tab in the main menu of the game. Labs can be constructed. As of patch 1.16, players can choose to play one of a selection of three labs.
In Labs, a game mode board is forced, and there is no guardians, but the player can change their Card Backs and Emotes, which are by default all Calculating.... The cosmetic loadout can be changed in the main screen for the lab for most labs, and on the deck selection screen for pre-constructed and constructed Labs.
The first Lab, A.R.A.M., was available with Patch V1.5.

Trivia and Visuals
- Instead of Victory, Defeat, or Tie Game; in Labs, the end-game messages read Experiment Succeeded, Experiment Failed, or Experiment Inconclusive respectively, with unique visual and sound effects, to fit the theme of the mode.
- There is unique sound effects and animations that play while the Labs section in the Play tab is selected, to convey the environment of 5Heimerdinger's Lab. In patches 1.6 and 1.7, it had a modified different background with pink smoke, sparks, and lights.
- In Labs, the selected Emotes default to being all Calculating..., to fit the theming of the mode.
- In early Labs, the emotes couldn't be changed, so players could only use Calculating.... See Patch History.
