Complete puzzle guide

The Wall is a single large ascent puzzle. The explorers start on opposite sides of the mountain and must use paired elevators to create a route to the top.

The puzzle becomes manageable once both players understand that every elevator movement changes the matching lift on the opposite side.

How the paired elevators work

The wall has a left area and a right area, and both areas contain elevators with the same five symbols.
The symbols are diamond, dynamite, pickaxe, minecart, and monster.
When an elevator rises on one side, the elevator with the same symbol descends on the other side.
You can ride inside an elevator cabin or stand on its roof. Both positions are required to climb.

Climb to the exit

Call the explorers Left and Right according to the side of the wall they enter. Do not move a lift until its rider confirms whether they are inside the cabin or standing on its roof.

Exact elevator route

Left waits at the left Diamond lift. Right enters the right Diamond lift, rides up one level, exits, climbs the stairs, and stands on top of the Dynamite lift.
Left enters the left Diamond lift, rides up one level, follows the stairs to the Dynamite cabin, and presses DOWN twice. This raises Right's matching Dynamite lift.
Right leaves the raised lift, heads left across the first lift, turns left down the slope, enters the Pickaxe lift, and presses UP once.
Right exits Pickaxe and follows the path back onto the roof of the Dynamite lift. Left, still inside the matching Dynamite cabin, presses UP once to lower Right.
Right steps off Dynamite, enters the Minecart lift, and presses UP twice. At the top, Right follows the path on the right, crosses the next lift roof, enters the Dinosaur-skull lift, and presses DOWN once before exiting.
Right follows the short path to the Pickaxe lift, enters it, presses DOWN once, exits, and returns up the slope to the Dinosaur-skull lift.
Left leaves Dynamite, goes down the stairs, enters the Minecart lift, and presses UP four times. Left exits, follows the right-hand path to the Dinosaur-skull lift, presses UP once, exits right, and waits at the wall lever.
Right enters the Dinosaur-skull lift, presses UP four times, exits left, and reaches the second wall lever.
At the cave entrance, each explorer holds one wall lever. Pull both levers at the same time to open the final gate.
