Trials of Form

Chalazae are albumen threads that hold the yolk. This clutch’s threads are tangled: uncross them without changing their connections. Any untangled layout works, including several separate shapes.

Drag an egg with your mouse or finger. Keyboard: Tab selects an egg, arrows move it, Shift + arrow makes a fine step. Leave space between eggs so that every thread is visible.

A useful move may temporarily add crossings. A hint shows a step towards one possible untangled form. Undo and redo also count as moves; hints are noted in your result. Time starts with your first touch of an egg and stops on pause, when the tab is hidden or when you leave the game.
