Does practising on a backup world break a Minecraft challenge's rules? That question runs through SB737 Reacts' only new upload, and viewers are drawing distinctions between testing a difficult move and undoing a failed attempt.
In "This Hardcore World was CHEATED!!", SB737 reacts to reefwon's investigation of Mud Flaps' Hardcore Skyblock run. This is commentary on another creator's investigation, with gameplay clips supplying the material for scrutiny. Reefwon points to backup worlds, changes in hotbar items and an ender-pearl escape whose trajectory he argues does not fit the game's mechanics.
SB737 doesn't simply leave it at the accusation. Towards the end, he considers alternative explanations and acknowledges the substantial work behind Mud Flaps' videos: "I don't think you can take away the fact that Mud Flaps does put hundreds and hundreds of hours into his videos..."
The comments add a suitably technical second conversation. Some viewers suggest that the no-backups rule could distinguish practice copies from restoring lost progress. Others discuss whether a stream can miss a frame that appeared in the game, or how logging back in affects momentum. Several also say they initially mistook the title for an accusation about SB737's own world.
The upload has reached roughly 218,000 views and is the channel's busiest video right now. The previous Dream investigation continues to draw attention, though at a gentler daily pace.
Across the catalogue, SB737 Reacts gained about 1.3 million views this week and added subscribers, although its present daily viewing is well below its usual level. Among nearby Minecraft channels, Johnny World had a particularly busy week, while unsorted guy was quieter. For SB737 Reacts, one upload supplied plenty to pick apart, right down to individual frames.

What viewers say
I almost thought SB's world was cheated but then I saw SB737 Reacts!
@thekingofminecraft5710See it on YouTube5:50 yes its possible for the frame to be skipped if stream is 60fps and ur game is more than 60
@Fool_LOTMSee it on YouTubeMy thought for his no backups rule could’ve been that it was misinterpreted. Maybe by no backups he meant he wasn’t gonna use backups in case of world corruption since in his actual attempts he was only using backups to practice things in this pattern
