He 'Solved Every Board Game'—Then Lost to His Teacher: The Twist in Mark Rober's Video

A video titled I Solved Every Board Game sounds like guaranteed victory. But in Mark Rober's 28-minute, 54-second experiment, his old teacher had the last laugh. Beneath the engineered tricks sits a warmer question: what does it mean to remember a good teacher?

Rober invited his former statistics teacher, Mr. Malloy, who had helped with his Guess Who? strategy, into a six-game showdown. Rober won Connect Four, tic-tac-toe and Jenga; Malloy won Battleship and Monopoly, while Rober's own game ended tied. At 3–3, Malloy also took the Hungry Hungry Hippos-style tiebreaker. Rober even brought an air cannon to Jenga.

Trari's October 29 record put the video around 13.92 million views, while RankTube's October 28 snapshot listed 12.4 million views, 172,000 likes and 3,242 comments. Among the English-language YouTube comments reproduced with links by Trari are jokes about a glasses-on-glasses gag and admiration for the respect shown to a teacher. These are not specifically Korean comments.

Three kinds of response stand out in comments linked and reproduced by Trari. Humor: @Archetapp enjoyed a glasses-within-glasses gag, and @matthewpollock9685 joked about how long Monopoly might take. Appreciation: a teacher commenting as @miranina1585 thanked Rober for his lasting respect for Malloy. Critique: @macethorns1168 noted that ideal tic-tac-toe ends tied, and @ShaharHarshuv questioned the assumptions of a Battleship probability strategy. These are attributed excerpts collected by Trari, not a complete independent review of YouTube's comments.

The Guess Who? strategy resembles repeated information splitting, while Jenga depends on friction and changing loads. But a strategy based on expected behavior can fail when an opponent deliberately changes that behavior—a limitation some viewers pointed out.

Verified from public sources: Mark Rober published video ID 26P1KyvrmjI on October 24, 2026; Trari logged 13,919,044 views by October 29. The Creator Wire independently described Malloy's tiebreaker win. Trari's chapter links locate Jenga at 18:22, the air cannon at 21:11 and the tiebreaker at 27:24. These details were cross-checked from coverage and metadata, not by direct playback of the full video. Counts and comments can change.

A useful next question is whether a supposedly winning strategy still works against friends who adapt. The video also invites viewers to notice the long-lasting respect for Malloy. We found no independent basis for claiming the same reactions spread across Korean forums.
