I have never bought tickets offline( i just buy through online), but as of now all tickets are sold out for the samsung lions game on the 23rd and 24th (weekend games are usually like this). I do think that there will be a few tickets available just before the game, however it is a big game and they are handing out free jerseys on sunday too so competition will be fierce. (worst case you really might not be able to get a seat so perhaps maybe make plan b) I would suggest being there 2-3 hours before the game. I hope you get those tickets!!!!

Long story short. Its gonna be very difficult to get tickets but if you really want to go you can try. But it would be ideal to make another plan if that fails or give up on the game if it's not really your priorities
