Kai Cenat challenges Minecraft Hardcore doubters as IShowSpeed duo faces one rule that could change everythingKai Cenat has pushed back at people who think his Minecraft Hardcore challenge with IShowSpeed will take months or even years. The pair began their second marathon on August 7, with a goal of defeating every boss in the game. Kai said he is confident they can finish much sooner because both he and IShowSpeed are gamers. They have given themselves 10 days for the challenge.Kai Cenat defends Minecraft Hardcore challenge with IShowSpeedDuring the first day of the marathon, Kai reacted to people who believed the challenge could take a very long time. Some viewers suggested three days would already be a difficult target, while others thought the duo could spend months trying to finish.Kai did not seem worried about those predictions. He said, “Three days? So y’all think it’s going to take three days? See, that’s what I like. I like that right there, bro. Because a lot of people think it’s going to take months, years. The whole time, they don’t understand, bro. Like, I’m a gamer, bro! And he (IShowSpeed) is a gamer, bro! So, when two gamers game, it’s over, bro! It’s over! I’ve got to see if Speed is ready. I don’t know if he is ready.”His comment led to a mixed reaction on X. Some viewers felt Kai was being too confident, while others said the criticism was simply based on how difficult Minecraft Hardcore can be.One X user, @Curothedirector, wrote, “Bro wants to grab all the ishowspeed’s viewers, but it ain’t gonna happen.”Another user, @dottwt_, took a different view, writing, “Ion think they were hating. js bein realistic”User @yesdeltaa also explained why the challenge could take longer than Kai expects, pointing to the amount of mining, luck and other work involved. The biggest risk is also clear: a bad run can force the players to start again.Kai Cenat and IShowSpeed set 10 day Minecraft Hardcore rulesKai Cenat and IShowSpeed have also made clear that their challenge has a 10-day limit. If they make progress but have a poor run, they can change their approach and focus on bosses across separate runs.Kai explained, “If it reaches the 10-day limit, and we have got any progress, and the one run is fricking terrible, we would then be able to defeat each boss on Hardcore in four different runs, so we can focus.”IShowSpeed then made one rule clear. Even if they defeat a boss during an earlier run, that progress will not carry over after the 10-day point. He said, “But we still have to beat every boss on Hardcore. So, even if we beat the boss already, it starts over. Once it gets to the 10-day period, everything starts over, even if we already did kill the boss.”That means the duo cannot simply collect wins across different attempts and call the challenge complete. They still have to defeat every boss under the rules they set.Kai also joked that failing the challenge could leave him and IShowSpeed as full-time Minecraft streamers. For now, though, Kai appears confident that two gamers can get the job done.
