Daily Stack Sort Guide: How the Tiles Move
Daily Stack Sort is built around one tile in your hand. Pick a column, put that tile at the top, and take the bottom tile back into your hand. Keep doing this until every column holds one color and the rainbow tile is left in your hand.
Quick answer
Your hand goes in at the top; the bottom comes back out
Each click moves a whole column down by one place. Watch the tile that comes out, reveal question tiles early, and stop using a column as soon as it turns into a locked single-color stack.
If you want a bottle or tube puzzle instead, compare all three choices in the Daily Sorting Games guide.
Daily Stack Sort Rules in Plain English
Choose a column
You may pick any column that has not already been completed and locked.
Push in your hand
The tile in your hand becomes the new top tile in that column.
Take the bottom tile
The old bottom tile leaves the column and becomes the tile in your hand.
Finish every color
Make each column one visible color and finish with the rainbow tile in your hand.
Every valid push uses one move. The board shows a move limit, so a long loop can leave you without enough moves to finish.
See What Happens in One Move
In this small example, the blue hand tile is sent into the top of the chosen column. The question tile at the bottom comes out and reveals that it is yellow.
Question Tiles Stay Hidden Until They Reach Your Hand
Hidden in the column
You cannot use the shape or position of a question tile to guess its color. It stays hidden while it is inside a column.
Visible in your hand
When the tile comes out at the bottom, its real color appears. That color remains known if you move it into another column later.
A column cannot complete while it still contains an unrevealed question tile, even if the hidden tile’s real color happens to match the others.
A Finished Column Locks for the Rest of the Game
A column is complete when every space is filled with the same visible color. The game adds a green check and stops that column from being selected again.
This is why a correct-looking column can still be finished too early. Before making the last matching push, check whether you still need that column to bring another tile around the board.
How You Win Daily Stack Sort
- Every question tile has reached the hand at least once and shown its color.
- Every column is full, uses one visible color, and is locked.
- Each completed column uses a different color.
- The single rainbow tile is in your hand, not inside a column.
Getting the colors right is not enough if the rainbow tile is still trapped in a column. Think of the rainbow as the spare tile that needs to come back out at the end.
A Simple Stack Sort Plan
Find the questions
Notice which columns still hide a color and how far each question tile is from the bottom.
Follow your hand
After every click, stop and look at the new hand tile before choosing the next column.
Build one color
Send matching tiles toward the same column, but do not lock it if you still need it.
Watch the move limit
A repeated circle may restore the same board while using up several moves.
Bring out the rainbow
Plan the last few pushes so the rainbow tile returns to your hand as the final columns lock.
You do not need to remember the whole board at once. A useful habit is to ask two small questions after each move: “What is in my hand now?” and “Which tile will leave the next column I choose?”
Undo, Restart, Share, and Saved Progress
Undo
Go back to the state before your last move. This is useful when a column locks sooner than you wanted.
Restart
Return today’s puzzle to its starting hand and columns. The puzzle itself does not change.
