The tallest Jenga tower falls apart at a 0.21° tilt — so AI found one that survives 25°
How tall can you build with 54 Jenga blocks?
A father-and-daughter Jenga habit turned into an optimization problem: with 54 standard blocks, the theoretical max is 4.05m, but that tower collapses at a 0.21° floor tilt. The author had Codex and Claude Code search 15 tilt levels from 0.1° to 25°, then tightened the physics checks so every design could actually be built block by block. The winners taper hard, put 40% of blocks in the bottom quarter, and lose 252cm of height to the first degree of tilt.
That first degree costs 252cm of height, while going from 1° all the way to 25° only costs another 134cm.
