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 shellphish.net/ictf/archive/…

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.

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 :(

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!
