Zaineking played Warcraft 3 Frozen Throne the first day it came out and loved playing on the ladder. His in-game name was SoMeThiNgGaY because initially he "would just rush wind riders and win which was really cheesy". He achieved 1500 orc wins with a 70% win rate. He also played World of Warcraft for a long time as a resto druid and DPS warrior on Tichondrius. His names were Zaine and Asix, respectively. He reached gladiator a couple times on his druid, but focused on topping the world DPS charts on his warrior. He quickly became Masters in Starcraft 2 playing zerg, but he only played the first few seasons and then switched to League of Legends. His in-game name in Starcraft was Zaine.
Zaineking started playing League of Legends because of his brother who showed him the game. League of Legends is the first MOBA Zaineking started playing. The name Zaine was taken, so he added king. Zaineking played ranked in Season 1 and went 15-0 with Mundo and almost hit Platinum immediately. He took some breaks when he got frustrated with Solo Queue, but he eventually came back because he didn't want to give up after committing so much time to the game.
