How to Solve BlindSlide: Plan the Slides Before You Commit

BlindSlide is a planning puzzle built around Rush Hour style blocks. Tap an arrow on a gray block to queue that block and direction. Each gray block can move only along its own axis, and when the plan executes it slides until something stops it. You must fill every countdown slot. The pink goal is not queued; after the gray moves run, it exits automatically if the lane is clear.

If a queued move cannot happen or the exit remains blocked, the whole plan rewinds. That is not a penalty animation. It is the game's feedback system.

Write the goal backward

Begin at the exit and trace the pink block's lane. List every gray block occupying that lane. Those blockers, and the blockers preventing them from moving, define the real puzzle.

A gray block that never touches this dependency chain is probably not part of the shortest plan. Do not queue it merely because it has an available arrow.

Know what “slide” means

A move is not a one-cell nudge. The selected gray block travels along its horizontal or vertical axis until another block or the boundary stops it. Predict the final resting position, not just the first empty cell.

That destination can help or hurt later moves. A blocker may leave the exit lane but park directly in front of the next block you intended to move.

Queue dependencies in the right order

If block A cannot move until block B clears its path, B must appear earlier in the countdown. Draw this as a tiny dependency chain in your head: clear B, move A, open exit.

BlindSlide plans fail most often because they contain the right moves in the wrong order.

Use every countdown slot deliberately

The plan runs only after every available slot is filled. If the obvious exit requires fewer moves than the countdown provides, the extra move still has to be legal and must not re-block the route.

Look for a harmless preparatory slide that creates space for a later blocker, or a move that parks a block away from the exit lane. There are no throwaway no-ops because a failed move rewinds the sequence.

Read the rewind like a debugger

Watch where execution first fails. If the second queued block cannot move, the mistake is in the state created by move one, not in the final exit. Change the earliest faulty dependency and keep the later moves that still make sense.

If all queued moves execute but the pink block cannot leave, inspect the exit lane again. One blocker may have shifted within the lane rather than leaving it.

A compact planning checklist

1. Trace the pink goal's path to the exit.
2. Identify every gray blocker on that path.
3. For each blocker, find what must move first.
4. Predict each selected block's final resting position.
5. Fill all countdown slots in dependency order.
6. On rewind, revise the first failed assumption.

A small dependency example

Suppose the pink goal needs to travel right, but a vertical gray block occupies its lane. That vertical block can move up only after a horizontal block above it slides left. The meaningful plan begins with the horizontal block, continues with the vertical blocker, and then lets the goal exit automatically.

Reversing the first two queued moves fails because the vertical block has nowhere to go. Choosing the same two blocks in the correct order succeeds. This is the central lesson of BlindSlide: the plan is defined by dependencies, not by which blocker looks closest to the exit.

Do not plan the pink block

The goal has no arrow in your countdown. Your responsibility is to clear its lane and keep it clear after every gray move. If the plan executes cleanly, the game handles the final pink slide. Spending mental effort on a nonexistent goal command only obscures the blockers that actually belong in the queue.

BlindSlide rewards careful observation more than fast tapping. Once you start reading each rewind as a test result, even a failed plan narrows the solution instead of sending you back to zero.
