How to play

How to Play Nested Shift

Find the target, reach the correct pushing side, and use undo when a move removes an essential route.

1. 01

   Choose Continue from the title screen to open the current puzzle. Inspect the player, boxes, walls, targets, and available floor.

2. 02

   Use WASD or the arrow keys to move. For a normal push, stand next to a box and move toward it; check that the space beyond it is available.

3. 03

   On the opening board, move right from the lower-left position, then up. This puts the player beneath the box and pushes it onto the outlined target.

4. 04

   Use Z to undo a move, X to redo, and R to restart when you want a clean board. Decide whether a small correction is enough before restarting.

5. 05

   Use the displayed Space or E enter/leave command when working with a shell. Recheck the room you are in and the position you will need outside.

About the game

Nested Shift

Nested Shift starts with a familiar problem: move a box onto an outlined goal. Its distinctive idea is that boxes can also contain rooms, making an entrance part of the puzzle rather than merely a decorative tile. Begin with the small board in front of you. Understand where the player can stand, which side of a box must be accessible, and what a push would block before thinking about a larger route.

The opening board gives a compact lesson. A white-faced player begins below and left of a central box, with the outlined target directly above that box. Move right to stand underneath it, then move up to push it onto the target. The order matters: approaching from the left would push in a different direction. This simple example introduces the habit that carries into more complicated rooms: solve the position of the player before solving the position of the box.

Choose this game when you want to pause and reason between inputs. There is more value in a planned three-move sequence than in quickly trying every direction. Undo and restart make exploration manageable, while the enter and leave controls give you a separate way to interact with room-like shells. Read the current board and its instructions instead of assuming every chapter uses exactly the opening arrangement.

Useful strategy

Make your next move count

The player’s position is half of the solution

A box does not move toward a goal simply because the goal is nearby. Your movement direction determines the push. For a target above a box, the useful standing square is beneath it. For a target to the right, you need access to the left side. Before moving the box, trace a walking route to that square. This prevents the common mistake of making a convenient push that leaves the box harder to approach.

The opening arrangement makes this distinction easy to see. The player is below-left, so moving up first would approach the side of the box rather than its underside. Moving right first creates the correct alignment. Think of this as two tasks: arrange your own position, then change the box position. In a larger room, write the same sequence mentally before committing to a push.

Walking around a box can be useful even when it looks like a detour. Empty floor is a resource because it gives you access to different pushing directions. When two routes reach the same standing square, prefer the one that leaves other boxes alone. Moving an unrelated box to shorten your walk can create an extra problem that was avoidable.

Protect the squares needed for later pushes

An empty target is not the only important square. The tile behind a box, a corridor around it, and the space beyond the intended push can all be necessary. Consider a box one square below its target. The push looks immediate, but it still requires a free standing position underneath. If another object occupies that square, handle the obstruction before pushing anything else into the same area.

Use corners and narrow passages as warning signs. A box against two walls has very few possible next directions. A box in a one-tile corridor may prevent you from walking to its far side. These are planning observations, not a claim that every shell behaves like an ordinary box. When a room introduces an unfamiliar interaction, examine the displayed command before treating the object as permanently trapped.

For several unfinished objects, ask which one has the least flexibility. A box with only one useful approach usually deserves attention before a box in open floor. Keep the flexible object out of the route needed by the constrained one. This order often makes a board easier without requiring you to predict its entire solution at once.

Use undo as a reasoning tool

Undo is most useful when it answers a specific question. If a push closes a corridor, undo it and inspect which standing square disappeared. Then choose a route that preserves that square. Merely alternating between random pushes and undo does not build a useful understanding of the board. Each reversal should help explain why the attempted route failed.

After a promising sequence, pause before trying an uncertain interaction. Remember the player’s location and the boxes that are already placed. If the next move makes the arrangement worse, a single undo returns you to a known position. Redo is available when you want to restore a move you deliberately reversed, so you can compare alternatives without immediately discarding your progress.

Restart is appropriate when the move history has become confusing or you want to replay a clearer plan. Before using it, identify one lesson from the failed attempt: a corridor that must stay open, a box that must move first, or an entrance that needs a different approach. A fresh board is more helpful when you return with a concrete change to the plan.

Keep inner and outer routes separate

A room inside a shell adds another layer of navigation. The official description introduces entering and leaving these spaces; the player also displays dedicated commands for that interaction. Begin by recognizing the entrance as a separate decision from ordinary movement. Do not assume a successful push, a completed inner target, and a useful outer position are the same event.

When entering a new room, take a moment to locate yourself again. Identify the immediate target and the exit interaction before moving objects. Plan a small local sequence, then consider what you will need after leaving. If your outer route depends on approaching the shell from a particular side, preserve that access while solving the smaller space.

If you lose track of the layout, return to the last clear position with undo rather than stacking more uncertain moves. A practical question is: what changed when I entered, and what will remain when I leave? The answer should come from the current board. Later chapters can introduce arrangements beyond the simple opening push, so use this method as a planning habit rather than a universal shortcut.

Read the result before moving again

After a push, check both the object and the route around it. In the opening puzzle, placing the box on the upper outlined tile produces a highlighted result. That is a useful sign that the local placement is correct. On a different board, look for the game’s own feedback and any remaining targets before concluding the puzzle is finished.

If a direction key appears to do nothing, click the game area once and check the proposed move. The destination may be a wall, the box may have no room beyond it, or focus may still be on the surrounding page. Separate an input problem from a planning problem. Repeating the same key rapidly makes neither easier to diagnose.
