Video summary

  1. 1:00Rober recalls learning a binary-search approach to Guess Who? from his high school statistics teacher.
  2. 8:52Mr. Malloy arrives for what he thinks is a CrunchLabs tour, then discovers the board-game challenge.
  3. 18:22Jenga turns into a lesson in weight shifts, manufacturing tolerances and friction.
  4. 21:11Rober introduces a wrist-mounted pneumatic air cannon for removing stubborn blocks.
  5. 22:34Monopoly brings property buying, trading and house-building strategies to the table.
  6. 27:24Hungry Hungry Hippos supplies the tiebreaker; the tournament result comes at 28:11.

A stubborn Jenga block meets an unusually elaborate solution: Mark Rober straps on a pneumatic air cannon. It is the kind of engineering intervention that makes perfect sense on his channel, even if the tower is under no obligation to cooperate.

"I Solved Every Board Game" is the week's biggest upload and the channel's busiest video right now, approaching 14 million views. Beneath the competitive setup sits a surprisingly practical lesson: loose Jenga blocks can emerge as the load shifts, and static friction behaves differently from friction once a block is moving. Knowing the physics, however, does not mean Rober can escape his former statistics teacher Mr. Malloy's trap of counting the remaining safe moves.

That teacher-student relationship gives the experiment its human center. Viewers are discussing the respect Rober shows Mr. Malloy, alongside the glasses-over-glasses gag and whether the Battleship strategy holds up when an opponent deliberately avoids the most likely targets. The description credits U.S. National Monopoly Champion Richard J. Marinaccio with contributing to the Monopoly research.

Rober's other new upload, "The Insane Science Hidden in These Toys," brings the week's releases to two. Both are drawing more daily views than the older "Last Cheater Standing Wins $10,000," whose CrunchLabs Casino gathering included Hank Green, Michael Reeves and Becky Stern.

The channel added roughly 700,000 subscribers over the week, although daily viewing is currently below its usual level. It has the largest weekly view gain among the science channels here; Kurzgesagt is also seeing above-usual daily viewing, while Vsauce and Veritasium are running more quietly than normal.

For Rober, the week's most memorable equipment remains that Jenga cannon: an impressive amount of machinery for a game usually played with fingertips.

    "The teacher's proudest moment."

    This should be the mentality of all teachers.

  • Turns out in the original rules of battleship ships are allowed to touch. Meaning you can completely circumvent this strategy by putting them all on edges. Your strategy also assumes random distribution where on battleship you are allowed to choose. So if you know your player will go for the middle you can just avoid the middle on purpose (even if you need a space)
