Basket keeps failing at the slatted panel by the locked door, searches the whole town for a missing piece, then asks for a hint that points to the periscope.
Basket finishes a row of button posts, gets a brass panel of slats out of a pedestal, and spends the episode on the winding blue line it shows by a locked door.
Basket reads glowing writing on a wall to crack the symbol grid, rides the floor down to a basement, and charges a blue crystal torch with an eel from the well.
Basket walks through a newly opened gate into the Watchtower area, lights a lamp with the torch and a telescope, and ends by aiming the telescope at a lens set in a window.
Basket explores the Crystal Lab, finds a sheet that turns five symbols into numbers, and tries them on a grid of symbol buttons, but one symbol never turns up.
Basket finds no use yet for the new tool, then spends most of the episode on a frame of sliding wooden blocks by a building in town, and gets the block through at the very end.
Basket starts Quern on an island of stone and wood, fits a missing stone piece into a door, and works out a ring dial on a barred gate from the drawings in the professor's letters.
Back at the start of the island, Basket opens a grid gate and wanders through hidden rooms, a green cave and a dark garden before the picture turns into live-action video.
Basket finishes a row of six combined panels, untangles two panels whose lines share a glass floor, and rides an elevator down to puzzles set in the floor.
Basket routes lines across a glass floor, solves mirrored panels hidden behind wooden posts, and reaches a row of panels that keep flashing through colors.
