Eight kernels. Zero excuses.

The Kernel & the Jacket

For Terence Tao’s love of proof and Jensen Huang’s love of compute. The imaginary jacket wants speed. The imaginary mathematician wants it to be right. You have to satisfy both.

Unofficial tribute · no endorsement

A small game for large brains.

Clear eight rooms by building answers, arranging bits, and catching mathematical traps. No timer. The proof gets the last word. Start with 800 points; an incorrect check costs 10.

These browser puzzles are miniatures of all eight Lean Kernel Challenge tasks. They do not run Lean or verify universal theorems; scores are game points, not official instruction counts. The challenge requires total, kernel-reducible algorithms with universal proofs. Its eight worked examples inspire the notebooks and may exceed competition limits. These are not claims of winning solutions.
