Mail Round is a free daily path puzzle. The mail has arrived, and every desk gets a letter. Draw one round from the mail cart that passes every free square of the office exactly once: no square twice, and no crossing your own line. Monday is a small office of 4 × 4. From Wednesday to Saturday the round has to end at the out-tray, and on Thursday and Friday thin walls stand in the way.
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.
- Draw with your finger. Drag from the mail cart through the squares. You can also tap the next square or use the arrow keys.
- Every square once. The counter shows how many squares your round has passed.
- Go back any time. Tap an earlier square of your round to return to it. Undo brings the round back.
- Stuck? The lightbulb lights the next squares, or takes you back to the last square from which the round can still be finished.
How to play Mail Round
- Start at the mail cart. Drag through the squares, one at a time, up, down, left or right.
- Pass every free square. Squares with a plant or a cabinet are blocked, and thin walls cannot be crossed.
- If there is an out-tray, it has to be the last square of the round.
- You win when the line has passed every free square.
What is on the floor
| Square | What it means |
|---|---|
| Mail cart | The round starts here. |
| Desk with an envelope | Still waiting for its mail. Pass it once. |
| Blue square | Already passed. You cannot enter it again. |
| Out-tray | The last square of the round, from Wednesday to Saturday. |
| Plant or cabinet | Blocked. The round goes around it. |
| Thin wall | Stands between two squares on Thursday and Friday. You cannot step through it. |
Tips for finding the round
- Look at the tight spots first. A square with only two open sides has to be entered through one and left through the other. That fixes a piece of the round before you start.
- Do not cut the floor in two. If your line splits the free squares into two groups, you cannot reach both any more.
- Do not leave a single square behind. A free square with only one way in can only be the last square of the round.
- Work back from the out-tray. The tray is the end, so the square before it is often easy to guess.
- Sweep in rows. Going back and forth like a snake covers the open areas. Then bend the snake around the obstacles.
How the week gets harder
| Day | Office | Squares to pass | Out-tray | Thin walls |
|---|---|---|---|---|
| Monday | 4 × 4 | 14 or 15 | No | None |
| Tuesday | 5 × 4 | 18 or 19 | No | None |
| Wednesday | 5 × 5 | 22 to 24 | Yes | None |
| Thursday | 6 × 5 | 26 to 28 | Yes | 2 to 4 |
| Friday | 6 × 6 | 32 to 34 | Yes | 4 to 7 |
Saturday plays like a Wednesday and Sunday like a Tuesday.
