Sulia JaCkky Khoomphetsavong is a professional Dota 2 player from Laos, also known by his nickname JACKBOYS. He is the second player in the world to reach the 12,000 MMR mark. He is known for playing for Indonesian team BOOM Esports as a carry, where he became the champion of GAMERS GALAXY: Invitational Series Dubai 2022.

Sulia admired Miracle- and wanted to reach the same high level as his idol, so he devoted a lot of time to the game. In January 2019, MyPro offered JaCkky to join the Alpha Red lineup. It was a very difficult decision for Sulia, as he was in his second year of university studying architecture and, as planned, he was to become an architect, plus it was necessary to move to Thailand. His father was against it, but his mom was fine with it. But still for the sake of his dream Sulia decided to join the team. Alpha Red became the first organization on the professional path of the player.

In February 2020, the player was signed by Thai cybersports organization Motivate.Trust Gaming. With Fearless, Masaros, Q, Boombell and LaKelz as coaches, JaCkky has dominated their region in dominant style. Sulia's team won tournaments such as ESL Thailand Championship 2020 Season 1, BTS Pro Series Season 3: Southeast Asia, and DOTA Summit 13 Online: Southeast Asia. However, the squad failed to achieve any serious results and in November 2020 JaCkky left the team, joining the Korean organization T1. According to the results of Dota Pro Circuit 2021: Season 1 - Southeast Asia Upper Division, the squad took the 3rd place, which allowed the five to participate in ONE Esports Singapore Major 2021 from the wild-card stage. But our hero never went to it, as in March 2021 he was expelled from the Korean cybersports organization.

In April 2021 Motivate.Trust Gaming presented a new lineup, which included JaCkky, as well as three of his former teammates Fearless, Masaros and Q, the fifth player of the new lineup was LionaX. Sulia's team did not achieve much results - the only significant one was a victory at BTS Pro Series Season 6: Southeast Asia. In February 2022, it was revealed that JaCkky was invited to BOOM Esports as a stand-in for the DPC Southeast Asia Regional Finals. After winning this tournament BOOM Esports officially announced that Sulia JaCkky Khoomphetsavong was the team's new carry. In the new team, the player played in many major tournaments, such as ESL One Stockholm Major 2022, ESL One Malaysia 2022 and PGL Arlington Major, but did not achieve any special results there. JaCkky also participated in The International 2022, where he took tenth place.

• December 8, 2022 - JaCkky joined Bleed Esports.

Under his new tag Sulia showed a good result at the regional DPC league, after which he unsuccessfully tried to qualify for The International 2023 and ESL One Kuala Lumpur.

2024 started with qualifiers for the big championships, but failed to take part in at least one, including the Riyadh Masters 2024 and The International.

In October, Sulia joined BOOM Esports and qualified for ESL One Bangkok 2024, but failed to advance past the group stage.

Roster started 2025 with a 14th place finish at DreamLeague Season 25. Later, the roster competed at FISSURE Universe Ep.4, finishing in 11th place and 13th at DreamLeague Season 26.

In 2025, the team qualified for The International 2025 but couldn’t reach the playoffs and finished the tournament in 15th place.
