Kongai is a Collectible Card Game where two players duel. It was developed by David Sirlin and is run by Kongregate. The game was in closed beta until July 10th, 2008. Since that date, Kongai has been available to the general public. However, a second closed beta with 40 new cards began on September 17th, 2009. These new cards became available to the public through weekly challenges on April 3rd, 2010. During 2020, Kongai was bugged with decks, skill rank, wins and losses not displaying properly. Decks could't be built and playing multiplayer didn't work at this time. Attempting to do either displayed an error. Thankfully in 2022, a Discord user by the name of Matrix4348, the latter has found a way to play Kongai after Adobe Flash became defunct. This Discord Server hosted by Anonymouselbow and Matrix4348 has instructions on doing so.
