Can I create a puzzle game on my phone?
Public rooms, catalog starts, and invite links all work in a mobile browser — no separate app. Screens are small, so lower the piece count for easier play. Invite links work across devices: phone and computer can join the same room.
Lower the piece count a bit
A phone shows less of the board at once than a computer. About one hundred pieces is usually easier than near a thousand. Pinch to zoom, find edges, then drag pieces into place. If the image is dark or colors are similar, lower the count before you start.
Invite links work across devices
A room created on the phone uses the same Invite link as on desktop; opening it on a computer joins the same room.
With a custom photo, the other device also needs the same original file, or they only see blank pieces.
Better after signing in
Mobile browsers often close pages in the background. After you sign in and join, the room is saved under My Puzzles, so you need not dig through chat for old links. Pieces others place while you are away stay; re-enter and continue.
