Collection of my best puzzles.

Puzzles that I have created in collaboration with other puzzle authors.

Puzzles that include customized elements, that obviously influence how the chamber looks and possibly works.

Puzzles with medium or unclassified difficulty.

Co-op puzzles.

Puzzles that you must know and use a glitch to solve. In these puzzles I first teach the principles to the player, before requiring them.

Portal 2 puzzles that either require some serious thinking or rely on difficult maneuvers to complete.

Puzzles with expected blind playthrough time of 1-5 minutes.
