Tidy Trays: A Free Daily Sorting Puzzle

Tidy Trays is a free daily sorting puzzle. The folders on the desk are mixed up, and each filing tray holds only a few of them. Pick up the top folder of a tray and put it on an empty tray or on a folder of the same color. The desk is tidy when every tray holds a single color. The game also shows the fewest moves in which the day can be solved, so you can see how close you came. Monday has 3 colors. Friday has 6 colors and 24 folders.

No sign-up and nothing to install. It runs in your browser on a computer or a phone, and your progress is saved on your device.

  • Two taps per move. Tap a tray to pick up its top folder. Tap another tray to put it down.
  • One simple rule. A folder goes onto an empty tray, or onto the same color. A full tray takes nothing more.
  • A number to beat. The fewest possible moves are shown next to your own count. Solving the puzzle is enough to win. Matching the number is the extra challenge.
  • Stuck? The lightbulb shows the next move of a shortest way from where you are. If there is no way left, it undoes a move.

How to play Tidy Trays

  1. Look for a color whose folders sit near the top of their trays. It is the easiest one to collect.
  2. Move folders that are in the way onto an empty tray.
  3. Build each color from the bottom of a tray upwards.
  4. You win when every tray is empty or full with one color.

Tips for fewer moves

  • Keep an empty tray as long as you can. It is your only room to maneuver. Filling both early often leads to a dead end.
  • Finish a color to free a tray. A tidy tray is done, and the tray you emptied on the way is free again.
  • Look at the bottoms. The folder at the bottom of a tray decides which color that tray will probably hold.
  • Do not shuttle. Moving a folder back and forth costs two moves and changes nothing. Undo instead.
  • Plan before you bury. Before you cover a folder, check where its color is being collected.

Frequently asked questions

Is Tidy Trays free?

Yes. There is no account, no download and no paywall.

Is this like a ball sort or water sort puzzle?

It belongs to the same family of sorting puzzles. Here you move one folder at a time between filing trays, every day has one new desk, and the game tells you the fewest moves possible.

Do I have to match the fewest moves?

No. The day is solved as soon as the desk is tidy. The fewest moves are there as a goal for players who want more.

How does the game know the fewest moves?

A program searches every desk that can be reached from the start. That is only a few thousand, even on Friday.

Can I get stuck?

Yes. A desk can reach a point where nothing useful can move. Use Undo, or the lightbulb, which takes back a move when there is no way left.

Do I need to see the colors well?

No. Every color has its own shape on the folder.

When does the new puzzle appear?

At midnight in your local time.

Can I play earlier puzzles?

Yes. Open the calendar button at the top of the game and pick any day from the past eight weeks.
