Thank you to everyone who helped organize and all the people playing for an awesome #ictf2021!. Congrats to @BushwhackersCTF, @saarsec and @We_0wn_Y0u for finishing Top-3!. We've archived the final scoreboard and the game website at

@saarsec @BushwhackersCTF This is brutal, @saarsec was on track to overtake @BushwhackersCTF , but these three ticks behind now have made it seem far out of reach. At the moment they would need 3800 points more each tick to win :(.

Wow, this is a super close game. Last tick, @saarsec needed 31624 points to catch up to @BushwhackersCTF. With around 16 ticks or so left, that means they need roughly 1976 more on each tick to catch up. They've been getting around that amount (1700-2000). This is insanse.

FIRST BLOOD: with @BushwhackersCTF's first blood on oly_consensus, all challenges of #ictf2021 have now been solved. With one hour to go, the consensus is that it's not about the flags you capture, it's about the bushes you whack along the way!.

FIRST BLOOD: QUADRA KILL!! @saarsec is on a tear, the 4th first blood in a row, they claim first blood on buffalo! No-Flags-There anymore after all, I guess.

FIRST BLOOD: Awesome job @saarsec for first-blood on swiss_keys! They found the holes in the keys!.

FIRST BLOOD: great job @BushwhackersCTF for getting first blood on gopher_coin!.
