Sandbox Gaming is a South Korean League of Legends team formed in 2018 after the acquisition of Team BattleComics and its LCK slot.
Sandbox first performed at the 2018 KeSPA Cup with Choi "Wizer" Ui-seok, Kim "Crush" Jun-seo, Kim "OnFleek" Jang-gyeom, Kim "Dove" Jae-yeon, Shin "Hollow" Yong-jin, Jang "Ghost" Yong-jun, and Cho "Joker" Jae-eup. The roster’s debut as Sandbox didn’t go particularly well, as the team finished the KeSPA Cup in ninth place.
The team welcomed Choi "Wizer" Ui-seok as the squad’s second top laner ahead of the 2020 LCK Spring Split. The team got off to a good start, keeping itself at the top of the standings for the first few weeks of play. Yoon "Justice" Seok-joon joined the team as a new substitute mid laner during the split.
Though not alawys as strong as it was at the beginning, Sandbox was a force to be reckoned with through most of the split. The team finished in fourth place with a 13-5 record, advancing to the playoffs. In the 2019 LCK Spring Playoffs, the team was knocked out by Damwon Gaming in the first round.
A similar situation unfolded during the 2019 LCK Summer Split. Sandbox started the split strongly, winning six matches in a row. That great performance couldn’t be maintained in the second half of the split as the team started losing more of its matches, eventually finishing with a 12-6 record.
In the 2019 LCK Summer Playoffs, Sandbox was eliminated in fourth place by SK Telecom T1. The team hoped to reach the 2019 World Championship qualification through the Regional Finals, but that final seed was instead taken by Damwon.
Going into the 2020 season, only Summit and OnFleek stayed with the team. Han "Lonely" Gyu-joon, Son "Punch" Min-hyuk, Yoo "FATE" Su-hyeok, Han "Leo" Gyeo-re, Moon "Route" Geom-su, and Kang "GorillA" Beom-hyun joined Sandbox’s new eight-man roster.
The new roster debuted at the 2019 KeSPA Cup in dominant fashion. Sandbox easily took wins against Griffin and T1 to reach the finals. In the finals, the team met Afreeca Freecs and was swept 3-0, but showed to be a dangerous force heading into the 2020 LCK season.
