Yes. Simply uncheck the box next to a member's name in the roster edit screen to mark them as absent for that shuffle.

Question 15

It's a mode that creates a standard classroom layout facing a blackboard (teacher's desk). You can easily build a grid-like seating chart by specifying the number of rows and columns.

Question 16

What is the maximum number of rows and columns?

Accepted Answer

While you can set larger numbers, we recommend keeping it around 10 columns or roughly 60 seats maximum so it fits nicely on your screen.

Accepted Answer

Currently, it is fixed at the top of the screen. However, you can express relative distance through how you arrange the adjacent seats.

It's a mode where you can freely place various tables of different sizes (4-seaters, 6-seaters, counters) to decide seating for banquets and events.

By dragging and dropping multiple rectangular tables (like '6-seater') right next to each other, you can seamlessly replicate long banquet rows.

Question 24

Can I fix the boss or teacher at the 'Seat of Honor'?

Accepted Answer

Yes. Using the 'Seat Grouping' feature, you can lock a specific member to a specific seat to ensure they get the seat of honor.

Question 25

Accepted Answer

Yes. By configuring 'Seat Grouping' with 'Male Only' and 'Female Only' conditions in a checkerboard pattern, you can achieve an alternating gender layout.

Yes. By saving it as a template via 'Save Current Layout' on the layout screen, you can quickly load the same venue layout even with a different roster.

Question 27

Accepted Answer

It allows you to assign labels like 'Boy', 'Girl', 'Sales Dept', or 'Newbie' to members. You can use tags to evenly distribute them or group them in specific seats.

It's a feature that lets you set specific distance rules between individuals, such as 'Make sure A and B never sit together' or 'A and B must sit right next to each other'.

Question 29

How is the distance calculated for 'Separate' rules?

Accepted Answer

It uses Manhattan distance (vertical moves + horizontal moves). For instance, 'Distance 2 or more' ensures they are never immediately adjacent front, back, left, or right.

Question 30

How do I put two people who don't get along at completely different tables?

Accepted Answer

Select those two in the 'Adjacency Rules' and set 'Separate' with a large distance value. Even in Party Mode, tables are evaluated based on coordinate distances to keep them apart.

Question 31

It says 'No arrangement found' and fails to shuffle.

Accepted Answer

This happens if you have too many conflicting rules, such as forcing more people into the front row than there are seats. Try relaxing the rules or adjusting the participant count.

Question 32

Can I perfectly distribute members with the same tag across all groups evenly?

Accepted Answer

The system tries its best to keep it random yet balanced. A strictly enforced 'Perfect Even Distribution' mode is currently under development. Please apply manual adjustments if needed.

Question 33

Is it possible to balance the gender ratio randomly?

Accepted Answer

Yes. By registering member genders and applying gender restrictions to specific seats, you can effectively control the male-to-female ratio across tables.

Yes! With the 'Roulette' mode on the results screen, you can project it on screen and do a drum-roll reveal. It's a huge hit at events and parties!

Can I look back at past seating results?

Accepted Answer

Yes. You can view your latest seating arrangements via the 'History' tab. (This assumes your browser data hasn't been cleared).

Accepted Answer

An automatic 'Avoid Past History' feature is under development. For now, you can manually use 'Adjacency Rules' to keep previous partners separated.

Question 45

I want to sync data between my iPhone and iPad.

Accepted Answer

Since data is currently saved locally in the specific device's browser, cross-device synchronization is not available at this time.

Question 46

Accepted Answer

As we don't offer cloud saves via account login yet, direct data migration during device changes or browser switches is not supported.

Accepted Answer

Unfortunately, no. Once you delete your history or clear browser cache, the data is permanently lost. Please be careful.

Question 48

The screen freezes when I hit the generate button.

Accepted Answer

If your condition rules are extremely complex, the algorithm may take too long. Please try reducing rules. If it gets stuck for over 10 seconds, refresh the page.

Drag & Drop for tables isn't working properly.

Accepted Answer

This could be a bug on older browsers or specific Android web views. Please try updating to the latest version of Chrome or Safari.

I'm getting an error when importing a CSV file.

Accepted Answer

Ensure your CSV is simple, has a 'Name' header in the first column, and is saved with UTF-8 encoding.

Question 51

The OCR (Camera text scanner) isn't reading names correctly.

Accepted Answer

Messy handwriting or dark/blurry photos can confuse it. Please try taking a bright, focused picture of clearly printed text directly from the top.

Most data, including names, is processed and saved entirely within your local browser. It is not sent to or stored on our servers (except for the OCR processing snippet).
