Announcing tkbctf4

Hello from tkbctf4 team!

Let us announce that we are going to hold tkbctf4 on the 2nd and 3rd of November.
On the first day will be an online CTF game, and on the second day the game (and some bonus games!) will be held at a CTF arena in Tsukuba, Ibaraki, JAPAN.
For those who won’t be able to visit Tsukuba on that day: Don’t worry. The online game will also be held on the 3rd.

We are anxious about your participation.

That’s all for now. Please stay tuned!
