Regular Battle (Japanese: レギュラーマッチ Regyuraa-Macchi / Regular Match) is a Multiplayer Mode that is not ranked, unlike it's Ranked Battle counterpart. As it is unranked, this implies that Regular Battle is more casual or easier to play. It usually has simpler strategies and more straight forward rules to play by.
To access the Regular Battle mode, the player must head to the base of Inkopolis Tower within Inkopolis Plaza or the base of Deca Tower within Inkopolis Square, in the cases of both Splatoon and Splatoon 2 respectively.
- Turf War: Currently the only online multiplayer game classified under the unranked Regular Battle mode.
- In Regular Battle (Turf War), walls do not count as covering the turf.
