Booked Solid is a free daily logic puzzle about the most familiar problem in office life: fitting a week of meetings into one calendar. Drag each meeting into a slot where everyone is free. A new puzzle appears every day. Monday is gentle. Friday takes real thought.
No sign-up and nothing to install. The puzzle runs in your browser on a computer or a phone, and your progress is saved on your device.
- One room. Only one meeting fits in each time slot.
- Everyone must be free. A meeting only fits where all of its attendees are available.
- Numbered meetings go in order. 1 comes before 2, and 2 comes before 3.
- Repeat meetings go on different days.
- Stuck? The lightbulb places one meeting for you. Hints are free.
How to play Booked Solid
- Pick a meeting from the list. The letters on it show who attends: A is Ana, B is Ben, and so on.
- Look at the calendar. Green slots are free for everyone in that meeting. Striped slots mean at least one attendee is busy, and the letter in the corner tells you who.
- Drag the meeting onto a green slot. You can also tap the meeting first and then tap the slot.
- Place every meeting to clear the day. If a tag turns red, a rule is broken. Move one of the red meetings.
The line above the calendar always tells you what the selected meeting needs, so you never have to memorize the rules. The buttons at the top let you undo a move, ask for a hint, start over, switch sound on, open past puzzles, and read the rules again.
The rules, one by one
| Rule | What it means | First appears |
|---|---|---|
| One room | The team shares a single meeting room, so two meetings can never overlap. | Monday |
| Availability | Each person has busy times. A meeting must sit where every attendee is free. | Monday |
| Fixed meetings | Grey meetings with a lock are already booked and cannot move. | Tuesday |
| Order | Meetings tagged 1, 2 and 3 are steps of one project. Each step must end before the next one starts. | Wednesday |
| Repeats | Meetings with the repeat mark are one meeting held several times. Each one goes on a different day. | Thursday |
Tips for solving faster
- Start with the meeting that has the fewest green slots. If a meeting fits in only one place, put it there first. Every other decision gets easier.
- Place long meetings and big groups early. A three-hour workshop with four people has very few options. A one-hour solo block can go almost anywhere.
- Check the repeats before you fill a day. They usually involve most of the team and each needs its own day.
- Work a numbered chain from both ends. Step 1 wants to be early in the week and step 3 wants to be late. That leaves the middle step a clear window.
- Look before you drop. Before you use a slot, ask whether it is the only place another meeting can go.
- Tap a name in the team list to see one person’s busy times across the whole week.
- Use a hint to confirm, not to guess. A hint either places a meeting correctly or sends back one that cannot stay where it is.
How the week gets harder
| Day | Calendar | Meetings to place | What is new |
|---|---|---|---|
| Monday | 9 to 1 | 5 or 6 | Availability only. Many answers work. |
| Tuesday | 9 to 2 | 6 or 7 | A fixed meeting is already on the calendar. |
| Wednesday | 9 to 3 | 7 or 8 | A numbered chain appears. |
| Thursday | 9 to 4 | 11 or 12 | Repeat meetings appear. |
| Friday | 9 to 5 | 13 or 14 | Every rule at once, and exactly one answer. |
Saturday plays like a Wednesday and Sunday like a Tuesday, for anyone who wants a puzzle with weekend coffee.
Frequently asked questions
Is Booked Solid free?
Yes. There is no account, no download and no paywall.
When does the new puzzle appear?
At midnight in your local time. After you finish, the result panel shows a countdown to the next one.
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. Solved days get a green check.
Does it work on a phone?
Yes. On a small screen it is often easiest to tap a meeting and then tap a green slot instead of dragging.
Is there more than one answer?
Early in the week, yes. Monday puzzles have many valid schedules. The options narrow each day, and every Friday puzzle has exactly one answer that can be reached by reasoning, without guessing.
Where is my progress saved?
In your browser, on the device you are using. If you close the page in the middle of a puzzle, it is still there when you come back. Clearing your browser’s site data resets your streak.
Is there sound?
Sound is off when you start, so the game is safe to open at work. Use the speaker button to turn it on.
